一、给自定义按键添加广播
修改PhoneWindowManager.java中的interceptKeyBeforeDispatching方法
/frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java
Override
public long interceptKeyBeforeDispatching(WindowState win, KeyEvent event, int p
BroadcastReceiver不仅可以接收系统广播，也可接收自定义的广播
1.定义一个广播接收器
代码如下:
public class MyReceiver extends BroadcastReceiver
{
public MyReceiver()
{
Log.i(TAG,”MyReceiver”);
}
//可用Intent的getAction()区分接
