Android: Button not showing after dynamic view

Question

I'm trying to dynamically put a bitmap in between a Textview and a Button:

<TextView android:text="TextView" android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
<LinearLayout android:layout_height="wrap_content" android:id="@+id/linearLayout1" android:layout_width="wrap_content" android:orientation="vertical">
</LinearLayout>
<LinearLayout android:layout_width="fill_parent" android:id="@+id/linearLayout2" android:layout_height="fill_parent" android:orientation="vertical">
    <Button android:layout_width="fill_parent" android:layout_gravity="fill_vertical" android:text="Button" android:layout_height="fill_parent" android:id="@+id/button1">    </Button>
</LinearLayout>

In my Main Activity I create my custom view and add it to the LinearLayout1

mView = new myView(this);
LinearLayout ll = (LinearLayout)findViewById(R.id.linearLayout1);
ll.addView(rView);

My problem is, that myView consumes all available space below of it.

What am I missing?

Thnx in advance.

try adding layout parms for the view.

Try to set layout Parameter dynamically for your custom View.

l1.addView(rView, new LinearLayout.LayoutParams(100, LayoutParams.WRAP_CONTENT));

similarly try to set left and right position dynamically

You should add the LayoutParams when adding the view:

ll.addView(rView, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

In case you want to add it to a specific position you should use: addView(child, index).

Hope this helps!

Hi Dimitris, I just checked your solution, but my problem remains. As i needed my view (which contains a square bitmap) on width*width size the following code gave me the correct picture:

ll.addView(rView, new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, ((WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getWidth()));
