TextView keeps popping up

Question

I have an activity where an TextView show up, and after that it fades out. However, everytime it has fade out, it pops back in. I tried

wtext.setText("");

But then my text just disappeares without fading out(after fading in). Does anyone knows how to fix this? Thanks! Kind regards.

This is my code:

public class SplashScreen extends Activity {



protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    Handler handler = new Handler();

    final TextView wtext = (TextView) (findViewById(R.id.wtext));

    Animation animation = AnimationUtils.loadAnimation(this, R.anim.abc_fade_in);
    wtext.startAnimation(animation);

    Runnable task = new Runnable() {

                @Override
                public void run() {
                    Animation animation1 = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.abc_fade_out);
                    wtext.startAnimation(animation1);
                    wtext.setText("");
                }
    };
    handler.postDelayed(task, 5000);

}

If you want something to happen after an animation is complete (in this case, hide a textview), you'll have to use an AnimationListener

Animation.AnimationListener myListener = new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {
            }

            @Override
            public void onAnimationRepeat(Animation animation) {
            }

            @Override
            public void onAnimationEnd(Animation animation) {
                wtext.setVisibility(View.INVISIBLE);
            }

        };
animation1.setAnimationListener(myListener);

您可以使用ViewPropertyAnimator ，它会更改视图的实际属性，而不仅仅是外观，因此在动画完成后它不会跳回到原始状态。

wtext.animate().alpha(0);

Answer 3

您可以尝试在元素上将fillAfter标志设置为true ：动画完成后，它将对其应用最终的转换。
