How to add EditText programmatically?
Here's what I wrote:
View RV = inflater.inflate(R.layout.fragment__dummy,container, false);
LinearLayout LL = new LinearLayout(getActivity());
EditText ET = new EditText(getActivity());
ET.setId(5);
ET.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
LL.addView(ET);
return RV;
Thank You!
LinearLayout layout=(LinearLayout)view.findViewById(R.id.linearLayout);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
android.widget.LinearLayout.LayoutParams.MATCH_PARENT,
android.widget.LinearLayout.LayoutParams.WRAP_CONTENT);
EditText edttext= new EditText(this);
edttext.setId("edittext");
edttext.setLayoutParams(params);
layout.addView(edttext);
You are creating the LinearLayout LL dynamically too.
You need to add it to RV like
((ViewGroup)RV).addView(LL);
Also you should set the LayoutParams for LL too

I'm having a problem with LinearLayout where I want to display a TableLayout after a TextView. I've tried modifying the LayoutParams however I can't seem to make it wrap (which I'm assuming I want it to do).
This is simplified version:
ScrollView sv = (ScrollView) findViewById(R.id.sv);
sv.removeAllViews();
LinearLayout ll = new LinearLayout(this);
sv.addView(ll);
//This is displayed
TextView tv = new TextView(this);
tv.setText("Hello World");
ll.addView(tv);
//This is not displayed - but if I remove the above view it will display...
TableLayout tl = new TableLayout(this);
ll.addView(tl, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
By specifiying Orientation as Vertical it worked for me:
ScrollView sv = (ScrollView) findViewById(R.id.sv);
sv.removeAllViews();
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
sv.addView(ll);
TextView tv = new TextView(this);
tv.setText("Hello World");
ll.addView(tv);
TableLayout tl = new TableLayout(this);
ll.addView(tl);
Currently, I am trying to code a textview and a edittext to align vertically using Linearlayout in android studio. I tried setting out the layout gravity and the other element but I cannot achieve what I want currently this is my code.
LinearLayout params3 = new LinearLayout(this);
params3.setOrientation(LinearLayout.VERTICAL);
params3.setGravity(Gravity.CENTER_VERTICAL);
LinearLayout.LayoutParams params2 = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params2.weight = 35;
params3.setLayoutParams(params2);
params2.height = convertDiptoPix(80,context);
//params2.leftMargin = convertDiptoPix(5,context);
TextView textView1 = new TextView(this);
textView1.setId(View.generateViewId());
textView1.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
textView1.setPadding(0,convertDiptoPix(1,context),0,convertDiptoPix(3,context));
textView1.setText("Receipt");
textView1.setTextColor(Color.parseColor("#000000"));
//textView1.setLayoutParams(params2);
textView1.setTextSize(convertDiptoPix(13,context));
EditTextIME editTextIME = new EditTextIME(this);
editTextIME.setId(View.generateViewId());
//editTextIME.setWidth(LinearLayout.LayoutParams.MATCH_PARENT);
//editTextIME.setMinimumHeight(LinearLayout.LayoutParams.WRAP_CONTENT);
editTextIME.setGravity(Gravity.BOTTOM | Gravity.CENTER_VERTICAL);
//editTextIME.setLayoutParams(params2);
editTextIME.setFocusableInTouchMode(true);
editTextIME.setKeyListener(DigitsKeyListener.getInstance("abcdefghijklmnopqrstuvwxyzöäüßñéúíóáèùòìàâãåæçëêìíîïôõûýABCDEFGHIJKLMNOPQRSTUVWXYZÖÄÜÕÔÒÔÓÙÚÛÝÑÇÈÉÊËÌÍÎÏÆÅÄÃÂÁÀØ01234567890()&*$%#!+-:;,._?¿/><[]{}|\\^ "));
editTextIME.setHint("Notes");
editTextIME.setInputType(InputType.TYPE_CLASS_TEXT);
editTextIME.setHorizontallyScrolling(true);
editTextIME.setTextSize(convertDiptoPix(13,context));
is anyone had anyone tried to code like vertical align in android studio? Can you share your idea?
You can try this,
LinearLayout parent = new LinearLayout(context);
parent.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
parent.setOrientation(LinearLayout.VERTICAL);
LinearLayout.LayoutParams params2 = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
TextView textView1 = new TextView(this);
textView1.setLayoutParams(params2);
textView1.setId(View.generateViewId());
textView1.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
textView1.setText("Receipt");
textView1.setTextColor(Color.parseColor("#000000"));
EditText editTextIME = new EditText(this);
editTextIME.setId(View.generateViewId());
editTextIME.setGravity(Gravity.BOTTOM | Gravity.CENTER_VERTICAL);
editTextIME.setLayoutParams(params2);
editTextIME.setFocusableInTouchMode(true);
editTextIME.setKeyListener(DigitsKeyListener.getInstance("abcdefghijklmnopqrstuvwxyzöäüßñéúíóáèùòìàâãåæçëêìíîïôõûýABCDEFGHIJKLMNOPQRSTUVWXYZÖÄÜÕÔÒÔÓÙÚÛÝÑÇÈÉÊËÌÍÎÏÆÅÄÃÂÁÀØ01234567890()&*$%#!+-:;,._?¿/><[]{}|\\^ "));
editTextIME.setHint("Notes");
editTextIME.setInputType(InputType.TYPE_CLASS_TEXT);
editTextIME.setHorizontallyScrolling(true);
// editTextIME.setTextSize(convertDiptoPix(13,context));
parent.addView(textView1);
parent.addView(editTextIME);
I have created programmatically a RelativeLayout which contains a button. I have also created a ScrollView which contains a LinearLayout in which are more than 10 TextViews. I want to have the RelativeLayout to be aligned top and fixed. When someone tries to scroll down, i want all the TextViews to go behind the fixed RelativeLayout. I want that button to be always visible. With this code, the RelativeLayout and the button are not displayed. Where am i wrong?
RelativeLayout (fixed)
- Button
LinearLayout
- ScrollView
- TextView
- + other 10 TextViews
Here is my code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final RelativeLayout relativeLayout = new RelativeLayout(this);
RelativeLayout.LayoutParams relativeLayoutParams = new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
relativeLayout.setLayoutParams(relativeLayoutParams);
this.setContentView(relativeLayout);
final Button restartButton = new Button(this);
restartButton.setText(R.string.restartButton);
LinearLayout.LayoutParams buttonParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
restartButton.setLayoutParams(buttonParams);
relativeLayout.addView(restartButton);
ScrollView scrollView = new ScrollView(this);
this.setContentView(scrollView);
final LinearLayout linearLayout = new LinearLayout(this);
LinearLayout.LayoutParams linearLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
linearLayout.setLayoutParams(linearLayoutParams);
linearLayout.setOrientation(linearLayout.VERTICAL);
scrollView.addView(linearLayout);
TextView textView1 = new TextView(this);
testTitle.setText(R.string.text_view1);
linearLayout.addView(textView1);
// + other 10 text views
}
Thanks!
In your code you replace your RelativeLayout with ScrollView. Just set firstly some LinearLayout as contentView and then put there your RelativeLayout via addView(relativeLayout) and the put there you scrollView also via addView(scrollView)
EDIT:
your new code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final LinearLayout mainLinearLayout = new LinearLayout(this);
LinearLayout.LayoutParams mainLinearLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
mainLinearLayout.setLayoutParams(mainLinearLayoutParams);
mainLinearLayout.setOrientation(LinearLayout.VERTICAL);
this.setContentView(mainLinearLayout);
final RelativeLayout relativeLayout = new RelativeLayout(this);
RelativeLayout.LayoutParams relativeLayoutParams = new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
relativeLayout.setLayoutParams(relativeLayoutParams);
mainLinearLayout.addView(relativeLayout);
final Button restartButton = new Button(this);
restartButton.setText(R.string.restartButton);
LinearLayout.LayoutParams buttonParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
restartButton.setLayoutParams(buttonParams);
relativeLayout.addView(restartButton);
ScrollView scrollView = new ScrollView(this);
mainLinearLayout.addView(scrollView);
final LinearLayout linearLayout = new LinearLayout(this);
LinearLayout.LayoutParams linearLayoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
linearLayout.setLayoutParams(linearLayoutParams);
linearLayout.setOrientation(linearLayout.VERTICAL);
scrollView.addView(linearLayout);
TextView textView1 = new TextView(this);
testTitle.setText(R.string.text_view1);
linearLayout.addView(textView1);
// + other 10 text views
}
EDIT 2: renamed first linearLayout to mainLinearLayout according to the comment
I am dynamically building a View here is what I have so far:
ScrollView sv = new ScrollView(this);
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
sv.addView(ll);
Spinner s = new Spinner(this);
s.setId(1);
List<SpinnerObject> list = this.datasource.getFacilitiesList();
ArrayAdapter<SpinnerObject> adapter = new ArrayAdapter<SpinnerObject>(this, android.R.layout.simple_spinner_dropdown_item, list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
s.setAdapter(adapter);
ll.addView(s);
setContentView(sv);
How do I set the width of my Spinner. I would like to know how to set it to wrap_content and a set value like 200dp
You can change the width of anything in code by adjusting its LayoutParams.
For example:
WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.width = 200dp;
getWindow().setAttributes(lp);
Let's say I have a LinearLayout, and I want to add two View to it. The first one contain editText, and the other one contain listview. I have been try code in java follows:
EditText inputViaText;
ListView historyInput;
protected static LinearLayout askTextLayout = null;
askTextLayout = new LinearLayout(this);
askTextLayout.setVisibility(LinearLayout.VISIBLE);
askTextLayout.setOrientation(LinearLayout.HORIZONTAL);
inputViaText = new EditText(this);
LinearLayout.LayoutParams askTextParams = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);
historyInput = new ListView(this);
LinearLayout.LayoutParams historyInputParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,70);
askTextLayout.addView(historyInput,historyInputParams);
askTextLayout.addView(inputViaText,askTextParams);
FrameLayout.LayoutParams frameAskTextParams = new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, Gravity.BOTTOM);
setContentView(R.layout.activity_main);
addContentView(askTextLayout, frameAskTextParams);
But, It just show the first one that i add. So when i code like follows:
askTextLayout.addView(historyInput,historyInputParams);
askTextLayout.addView(inputViaText,askTextParams);
It just show listView. When i code like follows:
askTextLayout.addView(inputViaText,askTextParams);
askTextLayout.addView(historyInput,historyInputParams);
It just show edittext. Anyone can help me?
Try this code in oncreate Method of your activity
context = this;
setContentView(R.layout.activity_main);
container = (LinearLayout) findViewById(R.id.Linear);
LinearLayout linearLayout = new LinearLayout(context);
linearLayout.setWeightSum(100);
ListView v1 = new ListView(context);
v1.setBackgroundColor(Color.CYAN);
LinearLayout.LayoutParams p1 = new LinearLayout.LayoutParams(0,
50);
p1.weight = 90;
v1.setLayoutParams(p1);
EditText v2 = new EditText(context);
v2.setText("Hello");
v2.setBackgroundColor(Color.WHITE);
LinearLayout.LayoutParams p2 = new LinearLayout.LayoutParams(0,
50);
p2.weight = 10;
v2.setLayoutParams(p2);
linearLayout.addView(v1, p1);
linearLayout.addView(v2, p2);
View view = new View(MainActivity.this);
LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT,
1);
view.setLayoutParams(lp);
view.setBackgroundColor(Color.BLACK);
container.addView(linearLayout);
container.addView(view);
Write this in activity_main:
<LinearLayout
android:id="#+id/Linear"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
</LinearLayout>
