Android Set the width of the text layout.

I have a list consisting of two text views. One for dates, one for names. Config.xml includes a listview:

<ListView android:id="@+id/ListView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/linlay"> </ListView>

Row.xml contains two text images:

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:paddingTop="4dip" android:paddingBottom="6dip" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <LinearLayout android:orientation="horizontal" android:id="@+id/linlay" android:layout_width="fill_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/left" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/right" android:layout_width="wrap_content" android:layout_height="fill_parent"/> </LinearLayout> </LinearLayout>

I have two more buttons for changing the contents of text views with each other, but since the contents of the first (initially) are wider than the second, I need to set the width of the layout in the code. Unfortunately, there is no txt.setLayoutWidth or similar command, and txt.setWidth () does not work. I need something like this in this code:

  Button sortname = (Button)findViewById(R.id.Button02); sortname.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { lv1.setAdapter(simpleAdapter2); LinearLayout.LayoutParams layoutparams = new LinearLayout.LayoutParams(200,120); txt1.setLayoutParams(layoutparams); } });

These two lines cause the application to freeze (stops unexpectedly):

 LinearLayout.LayoutParams layoutparams = new LinearLayout.LayoutParams(200,120); txt1.setLayoutParams(layoutparams);

You want to use the setLayoutParams TextView method and pass new LinearLayout.LayoutParams(width, height) , where width and height are integers that will indicate the width and height. You can keep the height and set the width as you want.
