Android EditText Resize Programmatically


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.

<strong>* JAVA RESIZE ATTEMPT *</strong>

@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()); }

<strong>* XML LAYOUT *</strong>

<LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="0.15" android:paddingLeft="5dp" > <TextView android:id="@+id/textView2" android:layout_width="110dp" android:layout_height="wrap_content" android:layout_gravity="left|center_vertical" android:text="Points Allowed: " android:textAppearance="?android:attr/textAppearanceMedium" android:textSize="15sp" /> <EditText android:id="@+id/editText10" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:ems="10" android:inputType="number" > </EditText> <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:src="@drawable/editpencil" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="0.15" android:paddingLeft="5dp" > <TextView android:id="@+id/TextView01" android:layout_width="110dp" android:layout_height="wrap_content" android:text="Points Used: " android:textAppearance="?android:attr/textAppearanceMedium" android:textSize="15sp" /> <EditText android:id="@+id/EditText01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:ems="10" android:inputType="number" /> </LinearLayout>

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);


you probably want to do this

getWidthBox.getLayoutParams().width=getWidthBox.getWidth(); setWidthBox.setWidth(getWidthBox.getWidth());


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>
