In Android how to get the width of the Textview which is set to Wrap_Content

Question

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. How Can i get the width of the textview after setting the text into it.

the code is as:

        LinearLayout ll= new LinearLayout(this);
        ll.setOrientation(LinearLayout.VERTICAL);
        TextView tv = new TextView(this);
        tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
        ll.addView(tv);
        tv.setText("Hello 1234567890-0987654321qwertyuio787888888888888888888888888888888888888888888888888");
        System.out.println("The width is == "+tv.getWidth());// result is 0
        this.setContentView(ll);

Please suggest. Thanks in advance.

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);                
    });

whats its equivalent for API 8 and above? – newton_guima Aug 28 '13 at 14:02
You can subclass TextView and override onLayout(). Call super.onLayout() from it and save TextView's width. That should work for any API level. – Const Sep 01 '13 at 15:09

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().

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 should use this:

textView.getMeasuredWidth();

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);

you can try this:

textView.measure(0,0);
int width = textView.getMeasuredWidth();

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 ));
    }

});

Thank you for this code snippet, which might provide some limited, immediate help. A [proper explanation would greatly improve its long-term value](//meta.stackexchange.com/q/114762/206345) by showing _why_ this is a good solution to the problem, and would make it more useful to future readers with other, similar questions. Please [edit] your answer to add some explanation, including the assumptions you've made. – Mogsdad Dec 20 '17 at 20:30

You can use this library to schedule the task of perform calculation on the width to the correct time after the view had been completely drawn

https://github.com/Mohamed-Fadel/MainThreadScheduler

Sample of use:

MainThreadScheduler.scheduleWhenIdle(new Runnable() {
       @Override
       public void run() {
           int width = textview.getWidth();
           int height = textview.getHeight();
           textview.setText( String.valueOf( width +","+ height ));
       }
   });
