每次点击都会改变Android图像按钮

Question

我希望我的图像按钮在每次点击时从一个图像更改为另一个图像。在我的代码中，这只能工作一次，图像改变，按钮不会改变onClick。

有人可以帮忙吗？

package com.wepromoteme.brapp; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.ImageButton; 

public class MainActivity extends Activity { 

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

setupPlayPauseButton1(); 

} 

private void setupPlayPauseButton1() { 
    ImageButton btn1 = (ImageButton) findViewById(R.id.play_pause1); 

    btn1.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      ImageButton btn1 = (ImageButton) 
findViewById(R.id.play_pause1); 
      btn1.setImageResource(R.drawable.play); 
     } 
    }); 
} 
} 

感谢

这是新代码：

public class MainActivity extends Activity { 

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

setupPlayPauseButton1(); 

} 

private void setupPlayPauseButton1() { 
    final ImageButton btn1 = (ImageButton) findViewById(R.id.play_pause1); 

    btn1.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 

      int i=0; 
      if(i%2==0) { 
       btn1.setImageResource(R.drawable.play); 
      } else { 
       btn1.setImageResource(R.drawable.pause); 

      } 
     } 
    }); 
} 
}

您应该扩展ImageButton并保持按钮的状态。所以它会改变你的点击监听器到这样的事情：

@Override 
    public void onClick(View v) { 
     MyImageButton btn1 = (MyImageButton) findViewById(R.id.play_pause1); 
     btn1.toggleState(); 
     switch(btn1.getState()){ 
      case 0: 
       btn1.setImageResource(R.drawable.play); 
       break; 
      case 1: 
       bt1.setImageResource(R.drawable.stop); 
       break; 
     } 
    }
