代码实现的功能是使得一个按钮在按下的实现显示光色图安，抬起的时候的显示黄色图案。

然后图案自己设置形状。当然还可以缺一角什么的。。。。。。

为Button绑定 OnTouchListener 监听器。

public class AppMain extends Activity{

private Button mButton;

/** Called when the activity is first created. */

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

ButtonListener b = new ButtonListener();

mButton = (Button)findViewById(R.id.button1);

mButton.setOnClickListener(b);

mButton.setOnTouchListener(b);

mButton.setBackgroundResource(R.drawable.green);

}

class ButtonListener implements OnClickListener, OnTouchListener{

public void onClick(View v) {

if(v.getId() == R.id.button1){

Log.d("test", "cansal button ---> click");

}

}

public boolean onTouch(View v, MotionEvent event) {

if(v.getId() == R.id.button1){

if(event.getAction() == MotionEvent.ACTION_UP){

Log.d("test", "cansal button ---> cancel");

mButton.setBackgroundResource(R.drawable.green);

}

if(event.getAction() == MotionEvent.ACTION_DOWN){

Log.d("test", "cansal button ---> down");

mButton.setBackgroundResource(R.drawable.yellow);

}

}

return false;

}

}

}
