我希望我的图片按钮在每次单击时从一张图片变为另一张图片。在我的代码中，这只有效一次，图像发生变化，按钮不会变回 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);
}
});
}
}
谢谢

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);
}
}
});
}
}
谢谢
