android settext for textview from relative weakreference

Question

I have an Activity and an inner class with name InnerClass in it which its updateAfterDelay() method must update a TextView . I want to avoid memory leak. So I changed InnerClass to static and try to use WeakReference like this:

public class MainActivity extends Activity {

    TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate ( savedInstanceState );
        setContentView ( R.layout.main );

        textView = (TextView) findViewById ( R.id.textView );
    }

    private static class InnerClass {

        private final WeakReference<TextView> targetTextView;

        public InnerClass(TextView targetTextView) {
            this.targetTextView = new WeakReference<TextView> ( targetTextView );
        }

        void updateAfterDelay() {
            targetTextView.setText ( "text" );
        }

    }

}

But on targetTextView.setText ( "text" ); I get this compile error:

cannot resolve method 'setText(java.lang.String)'

How I can solve above problem?

Answer 1

It must be targetTextView.get().setText("").
