Could somebody help me?
For example, there is the following layout:
main.xml:
<LinearLayout
android:id="#+id/linearLayout_item"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/linearLayout_item_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<EditText
android:id="#+id/editText_item_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
... Other views, skipped ...
</LinearLayout>
<Button
android:id="#+id/button_add_alias"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="#+id/button_commit"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
I use button_add_alias to add views as they needed.
((Button) findViewById(R.id.button_add_alias))
.setOnClickListener(new View.OnClickListener() {
int position = 1;
public void onClick (View v) {
View view = getLayoutInflater().inflate(R.layout.alias, null);
((LinearLayout) findViewById(R.id.linearLayout_item)).addView(view, position);
position++;
}
});
alias.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout_alias"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<EditText
android:id="#+id/editText_alias"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
... Other views, skipped ...
</LinearLayout>
So, what is the best way to get data from programmatically added editText_alias views?
Firstly, iterate through your LinearLayout using getChildAt().
Then, retrieve the first child (which in your case will be the EditText) from your child view.
LinearLayout parent = (LinearLayout) findViewById(R.id.linearLayout_item);
for (int i = 0; i != parent.getChildCount(); i++) {
if (parent.getChildAt(i).getId() == R.id.linearLayout_alias) {
LinearLayout alias = (LinearLayout) parent.getChildAt(i);
EditText editAlias = (EditText) alias.getChildAt(0);
// do what you want with the EditText
}
}
If I understand what you are trying to do in order to grab the edit text you should be able to call
view.findViewById(R.id.editText_alias)

I want to update the style of the selected item inside a ViewPager.
How can I do this?
This is the UI design. As you can see, the "November" tab is selected, so the corresponding bar is highlighted in yellow.
The way I've implemented this is a ViewPager with a custom item (white, not highlighted):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.cardview.widget.CardView
android:layout_width="142dp"
android:layout_height="275dp"
android:layout_margin="0dp"
app:cardElevation="0dp"
app:cardBackgroundColor="#android:color/transparent">
<TextView
android:id="#+id/monthly_spend_month"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/December"
android:textColor="#color/aluminum"
android:textSize="20sp"
android:textStyle="normal"
android:layout_marginStart="22dp"
android:layout_marginTop="34dp"/>
<RelativeLayout
android:id="#+id/monthly_spend_card"
android:layout_marginTop="120dp"
android:layout_marginStart="22dp"
android:layout_width="120dp"

android:background="#drawable/monthlyspend_card_bg_inactive">
<TextView
android:id="#+id/monthly_spend_text"
android:textColor="#color/almost"
android:layout_marginTop="50dp"
android:layout_marginStart="22dp"
android:text="Total
spent"
android:textSize="#dimen/balanceDescTextSize"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/monthly_spend_amount"
android:textColor="#color/almost"
android:layout_marginTop="10dp"
android:layout_marginStart="22dp"
android:layout_below="#id/monthly_spend_text"
android:text="$ 254.98"
android:textSize="#dimen/balanceDescTextSize"
android:textStyle="bold"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
</androidx.cardview.widget.CardView>
</LinearLayout>
I plan on doing the highlighting programmatically.
Here's some adapter code:
#NonNull
#Override
public Object instantiateItem(#NonNull ViewGroup container, int position) {
layoutInflater = LayoutInflater.from(context);
View view = layoutInflater.inflate(R.layout.monthlyspend_item, container, false);
TextView monthlySpendMonth, monthlySpendAmount;
monthlySpendCard = view.findViewById(R.id.monthly_spend_card);
monthlySpendMonth = view.findViewById(R.id.monthly_spend_month);
monthlySpendAmount = view.findViewById(R.id.monthly_spend_amount);
monthlySpendMonth.setText(monthlySpendings.get(position).getMonth());
monthlySpendAmount.setText(monthlySpendings.get(position).getAmountSpent());
container.addView(view, 0);
return view;
}
Any help would be appreciated!
I thing you are missing click listener :
view.setOnClickListener(new OnClickListener(){
public void onClick(View v){
// do you stuff here
}
});
((ViewPager)container).addView(view, 0)
Also inside instantiateItem() make int position as final.
you should change your model (in your case "monthlyspendings") at the selected item position.
then notify the adapter
adapter.notifyDataSetChanged()
and finally, custom selected view according to the model. for exapmle :
if(monthlySpendings.get(position).isSelected) monthlySpendCard.setBackgroundColor(Color.parseColor("#fcd14b"));
I have created dynamic EditText boxes and spinner on Add button, but I don't know how to retrieve data from them. The whole code is available on this website.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
parentLinearLayout = (LinearLayout) findViewById(R.id.parent_linear_layout);
mText=(EditText) findViewById(R.id.number_edit_text);
}
public void onAddField(View v) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.field, null);
// Add the new row before the add field button.
parentLinearLayout.addView(rowView, parentLinearLayout.getChildCount() - 1);
parentLinearLayout.getChildAt(counter);
}
public void onDelete(View v) {
parentLinearLayout.removeView((View) v.getParent());
}
Try this, You can simply create loop and get all data which have added dynamically, like this :
Change your layout activity_main.xml because in demo they were doing wrong code for layout.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

android:paddingLeft="5dp"/>
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text=""
android:id="#+id/result"/>
</LinearLayout>
Code for getting all values of edit Text :
int count = parentLinearLayout.getChildCount();
for(int i=0; i<count; i++) {
LinearLayout linearLayout = (LinearLayout)parentLinearLayout.getChildAt(i);
EditText editText = (EditText)linearLayout.getChildAt(0);
String result = editText.getText().toString();
//You can result get data from edit text.
}
For Spinner Value :
int count = parentLinearLayout.getChildCount();
for(int i=0; i<count; i++) {
LinearLayout linearLayout = (LinearLayout)parentLinearLayout.getChildAt(i);
Spinner spinnerField = (Spinner)linearLayout.getChildAt(1);
String result = spinnerField.getSelectedItem().toString();
//You can result get data from spinner value.
}
mText=(EditText) view.findViewById(R.id.number_edit_text);
Put this in onAddField method.
When you want to get the text from the ediText you need to call
mText.getText().toString()
SOLVED THE CODE BELOW WORKS
If I have a layout similar to the one below:
Those five temp EditTexts represent some info the user can enter (like the price of an item, the order number, etc.) If the user wants to add another item they would click on the Add button and I want another 5 textviews to appear on the screen right above the two buttons but right below the previous set of the 5 EditTexts. Can someone give me a starting point on how I would do this.
My layout of the fragment goes like this:
I have a top level linear layout (Vertical Orientation).
Then a scrollview.
Inside the scrollview I have another linear layout.
In that linear layout I have those five EditText objects and the two buttons
The view above is a fragment (defined in the file below) which I pass to my FragmentAdapter in my MainActivity file:
public class Device extends Fragment {
ScrollView scrollView;
LinearLayout ll;
#Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.device_view, container, false);
scrollView = (ScrollView) rootView.findViewById(R.id.device_scroll_view);
ll = (LinearLayout) rootView.findViewById(R.id.layout_in_scrollview);
Button addButton = (Button) rootView.findViewById(R.id.add_another_device_button);
addButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
View temp = inflater.inflate(R.layout.edit_text_view_objects, container, false);
ll.addView(temp);
}
});
return rootView;
}
}
Here is my layout file for this fragment:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

</ScrollView>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:layout_marginTop="40dp">

android:layout_alignParentRight="true"/>
</RelativeLayout>
</LinearLayout>
edit_text_view_objects.xml:

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Name of Master Device"
android:gravity="center"
android:textSize="15dp"/>

android:layout_height="wrap_content"
android:hint="Device Name"
android:gravity="center"
android:textSize="15dp"/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Max SMS per day"

<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="15dp"
android:gravity="center"
android:layout_gravity="center"
android:hint="OS Version"
android:layout_marginTop="10dp"/>
</LinearLayout>
in your XML take
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/device_scroll_view">
<LinearLayout
android:id="#+id/layoutDynamic"a
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="center_horizontal">
</LinearLayout>
</ScrollView>
and create one more XML for your Item and design accordingly (It will add dynamically when you click on ADD)
dynamic_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/device_fragment_linear_layout"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="DeviceFragment"
android:orientation="vertical">
<TextView
android:id="#+id/etDynamic"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="15dp"
android:gravity="center"
android:layout_gravity="center"
android:hint="Color"
android:layout_marginTop="10dp"/>
</LinearLayout>
so come to java Code
// take the reference of LinearLayout
linearLayout = (LinearLayout) romptView.findViewById(R.id.layoutDynamic);
// Take the reference of Add button
Button addButton = (Button) rootView.findViewById(R.id.add_another_device_button);
addButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
final View addView = layoutInflater1.inflate(R.layout.dynamic_row, null);
final TextView textView1 = (TextView) addView.findViewById(R.id.etDynamic);
textView1.setText(otheret.getText().toString().trim()); otheret.setText(""); linearLayout.addView(addView);
}
});
#and if you want to remove particular item
removeIcon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
addView.getParent()).removeView(addView);
}
});
You can add these EditText through code at runtime
we can solve this, using List/Recycler view efficiently/easily
when ever you clicking on ADD add the item to list and notify the Recycler view adapter
and and removing also easy you just delete the item from list based on recycler View position.
No need to create Dynamic View here recycler view will do the job
// In Main Layout
<android.support.v7.widget.RecyclerView
android:id="#+id/recycleView_Stops"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/layoutSaveBottom"
android:layout_below="#+id/ll1"
android:layout_marginTop="#dimen/pad_10dp"
app:layout_behavior="#string/bottom_sheet_behavior" />
<TextView
android:id="#+id/tvAddOther"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center"
android:text="#string/icon_plus"
android:textColor="#color/colorPrimary"
android:textSize="40sp"
app:customFontPath="#string/roboto_regular" />
// design your layout item
---------------------
and when clicking on Add set user entered details
addOther.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
RouteElements routeElements = new RouteElements();
routeElements.setLatitude(latitude);
routeElements.setLongitude(longitude);
routeElements.setStopName(otheret.getText().toString().trim());
routeElementsArrayList.add(routeElements);
routeStopsAdapter.notifyDataSetChanged();
});
And in Your Adapter for removing the item
public void remove(int position) {
if (position < routeElementsArrayList.size()) {
routeElementsArrayList.remove(position);
notifyDataSetChanged();
}
}
I am trying to make a simple Checkbook app, whose MainActivity stores a list of transactions. I would like a TextView at the top and bottom of the screen that show the account balance and an option to add a new transaction, respectively. I would like a list of transactions in between that scroll. I was able to implement a ListView and add a header and footer view, but if the transaction list exceeds the size of the screen the headers and footers can scroll off screen.
Is there any way to position a ListView within the linear layout, or freeze the headers/footers to stay on the screen?
Here is my XML file so far:
<TextView
android:id="#+id/header_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/default_header_string">
</TextView>
<ListView
android:id="#+id/transaction_list_view"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</ListView>
<TextView
android:id="#+id/footer_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/add_transaction_string">
</TextView>
And here is my onCreate, which has no syntax errors but I am unable to click the footerview to add a transaction:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_checkbook);
ListView list = (ListView) findViewById(R.id.transaction_list_view);
// Create a new Adapter
mAdapter = new TransactionAdapter(list.getContext());
// Inflate footerView and headerView
LayoutInflater inflater = getLayoutInflater();
TextView headerView = (TextView) inflater.inflate(R.layout.header_view, null);
TextView footerView = (TextView) inflater.inflate(R.layout.footer_view, null);
// Set listener for footerView
footerView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent transactionIntent = new Intent(CheckbookActivity.this, AddTransactionActivity.class);
startActivityForResult(transactionIntent, ADD_TRANSACTION_REQUEST);
}
});
list.setAdapter(mAdapter);
}
use the below code. This will satisfy your requirement. I tried this and working for me.
Relative layout with below,above attributes. Relativelayout is better than Linear layout with weight method.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/relative"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent" >
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentTop="true"
android:gravity="center_horizontal"
android:text="ListView Heading" />
<TextView
android:id="#+id/textView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:gravity="center_horizontal"
android:text="ListView Footer" />
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/textView1"
android:layout_above="#id/textView2"
></ListView>
The UI will like this
Try this way, hope this will help you to solve your problem.
Instead of using header/footer just put as below code in your XML:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center">
<TextView
android:id="#+id/header_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/default_header_string">
</TextView>
<ListView
android:id="#+id/transaction_list_view"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
</ListView>
<TextView
android:id="#+id/footer_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add_transaction_string">
</TextView>
</LinearLayout>
Yes, you can do it with weightsum and layout_weight in linearlayout and also you can create this type of view using RelativeLayout.
1) In LinearLayout just add weightsum="1" to your linearlayout and add layout_weight="0.2" to each of your header and footer and add layout_weight="0.6" to your listview.
2) In relativeLayout add alignParentTop to your header and alignParentBottom to your footer and set listview to layout_below="#+id/header" and layout_above="2+id/footer"
I found a possible solution for your problem from a similiar post. Hope this helps you.
For what you are trying to accomplish to freeze the header/footer. It will be easier to use a relative layout to position the header/footer then have your listview in the middle
<RelativeLayout ...>
<TextView
android:id="#+id/header_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:gravity="center"
android:text="#string/default_header_string">
</TextView>
<ListView
android:id="#+id/transaction_list_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/header_view"
android:layout_above="#+id/footer_view">
</ListView>
<TextView
android:id="#+id/footer_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="center"
android:text="#string/add_transaction_string">
</TextView>
</RelativeLayout>
You can use a LinearLayout for this task. But I don't recommend it as it's a bit "hacky".
Get all the elements in a array: Example:- (weatherArray)
Loop through all the elements :-
Example:-
mainLayout = ((LinearLayout)refreshObj.get("mainLayout"));
mainLayout.removeAllViews();
for (int i = 0; i < weatherArray.length(); i++) {
View childView = getLayoutInflater().inflate(R.layout.weather_row4_item, mainLayout,false);
TextView todayTempStatus = (TextView) childView.findViewById(R.id.todayTempStatus);
todayTempStatus.setText("");
}
This is an example without using listview, which we will populate lienarlayout using child view.
pretty easy question here, but I am not a java superuser quite yet.
I am using a ViewFlipper to provide a number of images, and a sliding-drawer to contain text specific to each image. I would like to have the text of the sliding drawer change to a specific string dependent on which child view is currently displayed.
Here is the XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:id="#+id/previous"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Prev" />
<Button
android:id="#+id/next"

</ViewFlipper>
</LinearLayout>
here is the java:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
flipper = (ViewFlipper)findViewById(R.id.flipper);
next = (Button) findViewById(R.id.next);
previous = (Button) findViewById(R.id.previous);
imageview1 = (ImageView)findViewById(R.id.imageView1);
imageview2 = (ImageView)findViewById(R.id.imageView2);
next.setOnClickListener(this);
previous.setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (v == next) {
flipper.setInAnimation(inFromRightAnimation());
flipper.setOutAnimation(outToLeftAnimation());
flipper.showNext();
}
if (v == previous) {
flipper.setInAnimation(inFromLeftAnimation());
flipper.setOutAnimation(outToRightAnimation());
flipper.showPrevious();
}
}
I'm sure the answer is really obvious, but that's why I need your help....THANKS!
When you call showNext() and showPrevious(), update your TextView to match.
