TextView not appearing in embedded LinearLayout - java

I am creating a simple tasklist app, and I want to programmatically add a TextView to an embedded LinearLayout. However, it is not showing up for some reason.
I try to add the TextView in MainActivity (irrelevant code removed).
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
setIntent(intent);
processExtraData();
}
private void processExtraData(){
Integer hours = 4;
Integer minutes = 35;
Integer seconds = 0;
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.linlayout);
TextView txt1 = new TextView(this);
final float scale = this.getResources().getDisplayMetrics().density;
int pixels = (int) (64 * scale + 0.5f);
ViewGroup.LayoutParams params = new LinearLayout.LayoutParams(0, pixels, 1f);
txt1.setLayoutParams(params); txt1.setText(hours.toString()+":"+minutes.toString()+":"+seconds.toString());
linearLayout.addView(txt1);
}
The embedded LinearLayout is declared in activity_main:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Super Reminder App!"
android:textAppearance="#style/TextAppearance.AppCompat.Large" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="12dp"
android:layout_marginBottom="12dp"
android:orientation="horizontal">
<EditText
android:id="#+id/taskAdd"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3.5"
android:hint="New Task" />
<Button
android:id="#+id/add"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1.5"
android:text="Add Task" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="12.5"
android:orientation="horizontal">
<ListView
android:id="#+id/tasks"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2.5"/>
<LinearLayout
android:id="#+id/linlayout"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2"
android:orientation="vertical"/>
</LinearLayout>
<Button
android:id="#+id/clearButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:text="Clear All" />
</LinearLayout>
I have already tested and made sure that onNewIntent and processExtraData are called. No errors are thrown either. Could this be a GUI issue? Any help would be greatly appreciated.

the problem I think in the ScrollView or something else that flushes to that.
thank you in advance .
You can use this function to display all the items in the listview.
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
listView.requestLayout();
}
Example:
setListViewHeightBasedOnChildren(yourlistview);

My JAVA codes:
public class UpdateActivity extends BaseActivity {
#BindView(R.id.dialogEndCount_buttonsLay)
LinearLayout dialogEndCount_buttonsLay;
private Window window;
private Activity activity;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_update);
//Initialize
ButterKnife.bind(this);
activity = this;
window = activity.getWindow();
//Set color to statusBar
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.setStatusBarColor(getResources().getColor(R.color.tabHomeColor));
}
//Set dynamically weight
dialogEndCount_buttonsLay.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
}
}
How can I fix this problem?
If you want set dynamically weightSum just use this code :
dialogEndCount_buttonsLay.setWeightSum(3f);
i hope help you
You're mixing LinearLayout and RelativeLayout. Change your layout to use a LinearLayout then weight is an available property on your LayoutParams.
val params = LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT)
params.weight = 1f

Increasing scrollview by adding buttons in a relativelayout (or linearlayout ) from bottom to top

Could really use some help with this one.
I'm trying to start with a single button at the bottom of my screen. When my counter++ button is clicked, a second button will be dynamically created above the button at the bottom of the screen. I was able to get this far, the problem is that the height of my scrollview doesn't increase when my buttons reach the top of the screen. Please see my example below.
Example
I'm assuming the scrollview only increases when items are added below the current view although if that's the case, is there no way I can create several buttons starting at the bottom going upwards?
Here my code.
XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:context="com.example.bbetzner.ttt.Map">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
>
<RelativeLayout
android:id="#+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<Button
android:id="#+id/count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="count++"
/>
<Button
android:id="#+id/floor0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="0"
/>
</RelativeLayout>
</ScrollView>
</RelativeLayout>
Java:
public void addfloor(){
Button myButton = new Button(this);
myButton.setText(""+floor);
margincount += 100;
RelativeLayout ll = findViewById(R.id.layout);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ABOVE, R.id.floor0);
lp.addRule(RelativeLayout.CENTER_HORIZONTAL);
lp.bottomMargin = margincount;
ll.addView(myButton, lp);
}
I've also tried doing this in a linear layout to see if the scrollview would increase but I couldn't figure out how to stack buttons from bottom to top in a linear layout. :S
Thanks in advance, yall are awesome!
#Texas use below code using that you are achieving what you want:

and here is Java File:

Button count;
int floor = 0;
private int margincount = 0;
#Override

super.onCreate(savedInstanceState);

lladdViews = (LinearLayout) findViewById(R.id.lladdViews);
count = (Button) findViewById(R.id.count);
count.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
addfloor();
}
});
}
public void addfloor() {
Button myButton = new Button(this);
myButton.setText("" + floor);
margincount += 10;
RelativeLayout ll = new RelativeLayout(this);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ABOVE, R.id.floor0);
lp.addRule(RelativeLayout.CENTER_HORIZONTAL);
lp.bottomMargin = margincount;
ll.addView(myButton, lp);
lladdViews.addView(ll);

Button Component Cuts off my custom View

My button component takes space of my custom view class,if i put more it takes up more space,any reason why is that
My oncreate method :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_control);
MyCustomPanel view = new MyCustomPanel(this);
DisplayMetrics metrics;
metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int height = getDPI(500, metrics);
int width = getDPI(800,metrics);
layout = (LinearLayout) findViewById(R.id.r2) ;
layout1 = (LinearLayout) findViewById(R.id.l2);
ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(width,
height);
layout.addView(view,params);
}

</LinearLayout>
these are the screen shots
Additionally is there anyway to set gravity of my custom view.??
Update your layout with this code.

This is my java code:
Context ctx2 = this;
String[][] arrayWithInformations = new String[5][];
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_nivo1);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
DatabaseOperations databaseOperations = new DatabaseOperations(ctx2);
Cursor cursorLogo = databaseOperations.getInformationsForLogos(databaseOperations);
// looping through all rows and adding to list
Integer i = 0;
if (cursorLogo.moveToFirst()) {
do {
String[] helperArray = {cursorLogo.getString(0),cursorLogo.getString(1),cursorLogo.getString(2),cursorLogo.getString(3),
cursorLogo.getString(4),cursorLogo.getString(5)};
arrayWithInformations[i] = helperArray;
i++;
} while (cursorLogo.moveToNext());
}
int firstRating = Integer.parseInt(arrayWithInformations[0][4]);
int secondRating = Integer.parseInt(arrayWithInformations[1][4]);
int thirdRating = Integer.parseInt(arrayWithInformations[2][4]);
int fourthRating = Integer.parseInt(arrayWithInformations[3][4]);
RatingBar rb0 = (RatingBar) findViewById(R.id.rb0);
rb0.setRating(firstRating);
RatingBar rb1 = (RatingBar) findViewById(R.id.rb1);
rb1.setRating(secondRating);
RatingBar rb2 = (RatingBar) findViewById(R.id.rb2);
rb2.setRating(thirdRating);
RatingBar rb3 = (RatingBar) findViewById(R.id.rb3);
rb3.setRating(fourthRating);
I get the rating values from database file and everything works fine , the stars are ok but when I rotate the phone they are all wrong. I know that when u rotate your phone the current activity gets loaded again, but it's the same code and it loads wrong. Maybe it's multiplying the stars.. I may sound funny but I have no idea what is going wrong. Someone please give me a lead..
I found out the problem !
android:shrinkColumns="1,0" android:stretchColumns="0,1"
Setting this to the TableLayout caused this strange issue.
Thanks everyone for your interest in helping me ..
