How to programmatically change the height and width of the layout of the frame?

Question

I am new to android.

I ran into one problem: I am adding a frame layout to my application, the code

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <FrameLayout android:id="@+id/frameLayout1"> <LinearLayout android:layout_height="wrap_content" android:id="@+id/linearLayout1" android:layout_width="fill_parent"> </LinearLayout> </FrameLayout> </LinearLayout> 

My problem is that I want to change the height of the frame layout in different screen orientations.

code example

  wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE); getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); Log.v("height","height"+wm.getDefaultDisplay().getHeight()); if(wm.getDefaultDisplay().getHeight() <= 427) { Log.v("height","111"); ((FrameLayout)findViewById(R.id.frameLayout1)).setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT)); } else { ((FrameLayout)findViewById(R.id.frameLayout1)).setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT)); } 

But he gives power close

If anyone has an idea, please help me.

Thanks in advance.

Answer 1

One way is to create a custom view and override the onLayout and onMeasure functions. In the onLayout function, you can override the width and height. See an example of the LabelView.java class here .

Answer 2

You need to use LinearLayout.LayoutParams (int width, int height, float weight)

 FrameLayout frameLayout = new FrameLayout(context); LinearLayout.LayoutParams layPra = new LinearLayout.LayoutParams(width,height,mWeight); layPra .gravity = Gravity.CENTER | Gravity.BOTTOM; frameLayout .setLayoutParams(layPra );
