嘿,我想知道你是怎么做的,所以当按下一个图像按钮时,它会改变颜色以显示它被按下了。
DragonFruitActivity.java
package com.Dragon_Fruit;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.ImageButton;
public class DragonFruitActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageButton playbutton = (ImageButton) findViewById(R.id.playbutton); playbutton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
setBackgroundResource(R.drawable.playbuttonselected);
// TODO Auto-generated method stub
startActivity(new Intent(DragonFruitActivity.this, playbutton.class));
}
private void setBackgroundResource(int playbuttonselected) {
// TODO Auto-generated method stub
}
});
ImageButton settingsbutton = (ImageButton) findViewById(R.id.settingsbutton); settingsbutton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
startActivity(new Intent(DragonFruitActivity.this, settingsbutton.class));
}
});
}
}
所以新活动应该是:
package com.Dragon_Fruit;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.ImageButton;
public class DragonFruitActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageButton playbutton = (ImageButton) findViewById(R.id.playbutton); playbutton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
arg0.setBackgroundResource(R.drawable.playbuttonselected);
// TODO Auto-generated method stub
startActivity(new Intent(DragonFruitActivity.this, playbutton.class));
}
});
ImageButton settingsbutton = (ImageButton) findViewById(R.id.settingsbutton); settingsbutton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
startActivity(new Intent(DragonFruitActivity.this, settingsbutton.class));
}
});
}
}

您可以查看this。您可以下载该示例,并将android:drawable
替换为您的图片。

您正在寻找的是选择器http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList
使用它们更改图像按钮颜色。

在onClick(...)方法中,您可以setBackgroundResource(...)
ImageButton playbutton = (ImageButton) findViewById(R.id.playbutton);
playbutton.setOnClickListener(new View.OnClickListener() {
@Override public void onClick(View arg0) {
setBackgroundResource(...);
startActivity(new Intent(DragonFruitActivity.this, playbutton.class));
}
}
(您还需要定义drawable以用作背景颜色)。
