好久没写了，看网上其他类似文章有点麻烦，我的方法较为简单，程序部分只改StatusBarService.java部分就可以了。

在StatusBarService.java

添加

import android.os.ServiceManager;<br /> import android.view.IWindowManager;<br /> import android.widget.ImageButton; 

添加定义控件：

ImageButton homeButton;//对应 "@+id/Stat_Home_button"<br /> ImageButton volUpButton;//对应"@+id/Stat_vol_raise_button"<br /> ImageButton volDownButton;//对应 "@+id/Stat_vol_down_button"<br /> IWindowManager windowManager; 

修改makeStatusBarView函数

private void makeStatusBarView(Context context)  

为

private void makeStatusBarView(final Context context)  

(至于为什么要加这个，不是很懂java，编译器提示要加就加上了-_-|||)

makeStatusBarView函数内部添加每个按钮的Listener来监听onClick

windowManager = IWindowManager.Stub.asInterface(ServiceManager.getService("window"));<br /> homeButton = (ImageButton)sb.findViewById(R.id.Stat_Home_button);<br /> homeButton.setOnClickListener(new View.OnClickListener(){<br /> public void onClick(View v){<br /> doKey(KeyEvent.KEYCODE_HOME);<br /> }<br /> });<br /> volUpButton = (ImageButton)sb.findViewById(R.id.Stat_vol_raise_button);<br /> volUpButton.setOnClickListener(new View.OnClickListener(){<br /> public void onClick(View v){<br /> doKey(KeyEvent.KEYCODE_VOLUME_UP);<br /> }<br /> });<br /> volDownButton = (ImageButton)sb.findViewById(R.id.Stat_vol_down_button);<br /> volDownButton.setOnClickListener(new View.OnClickListener(){<br /> public void onClick(View v){<br /> doKey(KeyEvent.KEYCODE_VOLUME_DOWN);<br /> }<br /> }); 

当按钮监听到onClick时就做相应的处理：

运行一个线程来把ACTION_DOWN和ACTION_UP事件injectKeyEvent,

看上去非常的简单，但是java在这里肯定做了不少事

private void doKey(final int eventCode){<br /> new Thread(new Runnable() {<br /> public void run() {<br /> long now = SystemClock.uptimeMillis();<br /> try {<br /> KeyEvent down = new KeyEvent(now, now, KeyEvent.ACTION_DOWN, eventCode, 0);<br /> KeyEvent up = new KeyEvent(now, now, KeyEvent.ACTION_UP, eventCode, 0);<br /> windowManager.injectKeyEvent(down, true);<br /> windowManager.injectKeyEvent(up, true);<br /> } catch (RemoteException e) {<br /> Slog.d("Input", "DeadOjbectException");<br /> }<br /> }<br /> }).start();<br /> } 

最后在interceptTouchEvent()函数里面判断一下

 ....

if (SPEW) {<br /> Slog.d(TAG, "Touch: rawY=" + event.getRawY() + " event=" + event + " mDisabled="<br /> + mDisabled);<br /> if ((mDisabled & StatusBarManager.DISABLE_EXPAND) != 0) {<br /> return false;}}<br /> int x1 = (int)event.getRawX();</p> <p> int Button_l = homeButton.getLeft();<br /> int Button_r = homeButton.getRight();<br /> if(x1>Button_l && x1< Button_r)<br /> {<br /> Slog.d("pressed homeButton and intercepted");<br /> return false;<br /> }</p> <p> Button_l = volUpButton.getLeft();<br /> Button_r = volUpButton.getRight();<br /> if(x1>Button_l && x1< Button_r)<br /> {<br /> Slog.d( "pressed volUpButton and intercepted");<br /> return false;<br /> }<br /> Button_l = volDownButton.getLeft();<br /> Button_r = volDownButton.getRight();<br /> if(x1>Button_l && x1< Button_r)<br /> {<br /> Slog.d("pressed volDownButton and intercepted");<br /> return false;<br /> }<br /> final int statusBarSize = mStatusBarView.getHeight();<br /> final int hitSize = statusBarSize*2; 

....

目的是消费掉对button的点击。

OK，就这样了
