Question:
I have a view in which I have two LinearLayouts - one with Text, EditText and a Button and one with just Text and EditText. I am trying to get the width of the second EditText (on the second line) to match the width of the first line. I have tried making it a TableLayout instead of just using LinearLayouts and now am trying to set the width programmatically. I get the width of the first EditText and try to setWidth of the second EditText, but it doesn't change sizes.

@Override
public void onWindowFocusChanged(boolean hasFocus) {
// TODO Auto-generated method stub
super.onWindowFocusChanged(hasFocus);
getWidthBox = (EditText) findViewById(R.id.editText10);
setWidthBox = (EditText) findViewById(R.id.EditText01);
Toast.makeText(this, "Meaured Width: " + Integer.toString(getWidthBox.getMeasuredWidth()), Toast.LENGTH_SHORT).show();
Toast.makeText(this, "Get Width: " + Integer.toString(getWidthBox.getWidth()), Toast.LENGTH_SHORT).show();
//Neither of these setWidth Lines Work Correctly
setWidthBox.getLayoutParams().width=getWidthBox.getWidth();
setWidthBox.setWidth(getWidthBox.getWidth());
}

Answer1:I solved it in a bit of a different way that makes the most sense to me. What I did was get the width of the pencil button via getWidth and then set the right-padding of the LinearLayout (each row is its own LinearLayout) to the width of that button. This seems to work perfectly and allows for the button to change size (based on screen size and DP) and the padding to react accordingly.
imageButtonWidth = (ImageButton) findViewById(R.id.imageButtonEdit);
linearLayoutPointsUsed= (LinearLayout) findViewById(R.id.linearPointsUsed);
widthOfEditButton = imageButtonWidth.getWidth();
linearLayoutPointsUsed.setPadding(5, 0, widthOfEditButton, 0);
Answer2:you probably want to do this
getWidthBox.getLayoutParams().width=getWidthBox.getWidth();
setWidthBox.setWidth(getWidthBox.getWidth());
Answer3:I would just use relative layout and alignRight the second TextView to the first
try this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="@+id/TV01"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_marginTop="8dp"
android:text="Test Text1: "
android:textSize="18dp" />
<EditText
android:id="@+id/ET01"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:layout_toLeftOf="@+id/Btn"
android:layout_toRightOf="@+id/TV01"
android:text="test text" />
<Button
android:id="@+id/Btn"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_alignParentRight="true"
android:text="myBtn" />
<TextView
android:id="@+id/TV02"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_below="@+id/TV01"
android:layout_marginTop="8dp"
android:text="Text2: "
android:textSize="18dp" />
<EditText
android:id="@+id/ET02"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:layout_alignLeft="@+id/ET01"
android:layout_alignRight="@+id/ET01"
android:layout_below="@+id/TV01"
android:text="test text" />
</RelativeLayout>
