I am trying to add a text to the textview for which i have set the width as Wrap_content. I am trying to get the width of this textview. But its showing 0 in all the cases.
When are you calling this? Has it already been drawn to the screen?
It sounds like you are calling getWidth()
too early.
You can also take a look at this question.
you can try this:
textView.measure(0,0);
int width = textView.getMeasuredWidth();
You can not get the width of a View with dynamic size before the layout is completely built. That means there is no way you can get it in onCreate(). One way would be to create a class that inherits from TextView and overrides onSizeChanged()
.
this works for me:
RelativeLayout.LayoutParams mTextViewLayoutParams = (RelativeLayout.LayoutParams) mTextView.getLayoutParams();
mTextView.setText(R.string.text);
mTextView.measure(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
int width = mShareTip.getMeasuredWidth();
//use the width to do what you want
mShareTip.setLayoutParams(mShareTipLayoutParams);
hello use this method:
textview.post(new Runnable() {
@Override
public void run() {
int width = textview.getWidth();
int height = textview.getHeight();
textview.setText( String.valueOf( width +","+ height ));
}
});

Views with the dynamic width/height get their correct size only after a layout process was finished (http://developer.android.com/reference/android/view/View.html#Layout).
You can add OnLayoutChangeListener to your TextView and get it's size there:
tv.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
public void onLayoutChange(View v, int left, int top, int right, int bottom,
int oldLeft, int oldTop, int oldRight, int oldBottom) {
final int width = right - left;
System.out.println("The width is == " + width);
});
