我该如何让动画开始接触和停止再次感动？ [英] How do I make animation start on touch and stop once touched again?

问题描述

我有一个Android应用我做的一切工作，但我想添加一个code，将停止动画，一旦我再次触摸屏幕。正如你可以在code看到我的动画开始播放，但我只能通过退出程序停止它，我想能够触摸屏第二次停止动画和声音的播放。

感谢你。

解决方案

更改您onTouch code以下内容：

 公共布尔onTouchEvent（MotionEvent事件）{
  如果（event.getAction（）== MotionEvent.ACTION_DOWN）{
    如果（animation.isRunning（））{
       mp.stop（）;
       animation.stop（）;
    }其他{
       mp.start（）;
       animation.start（）;
    }
    返回true;  }
  返回super.onTouchEvent（事件）;
}
 

I have an Android app I made and everything works but I want to add a code that would stop the animation once I touch the screen again. As you can see in the code I got the animation to start but i can only stop it by exiting the program, I would like to be able to touch the screen a second time to stop the animation and the sound playback.

Thank You.

import android.app.Activity;
import android.os.Bundle;
import android.graphics.drawable.AnimationDrawable;
import android.media.MediaPlayer;
import android.view.MotionEvent;
import android.widget.ImageView;



public class WigleActivity extends Activity {
/** Called when the activity is first created. */

MediaPlayer mp;
AnimationDrawable animation;

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

    mp = MediaPlayer.create(this, R.raw.sexy);

    ImageView imageView1 = (ImageView)findViewById(R.id.imageView1);
    imageView1.setBackgroundResource(R.anim.wanim);
    animation = (AnimationDrawable) imageView1.getBackground();       
}

protected void onPause() {
    super.onPause();

    mp.release();
    finish();
}

public boolean onTouchEvent (MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
    mp.start();
    animation.start();
    return true;

}
return super.onTouchEvent(event);
}

}

解决方案

Change you onTouch code to the following:

public boolean onTouchEvent (MotionEvent event) {
  if (event.getAction() == MotionEvent.ACTION_DOWN) {
    if (animation.isRunning()) {
       mp.stop();
       animation.stop();
    } else {
       mp.start();
       animation.start();
    }
    return true;

  }
  return super.onTouchEvent(event);
}
