使用adb发送广播的小DEMO

使用adb发送广播的小DEMO。

动态注册广播：

public class MainActivity extends Activity {
 private static final String TAG = "MainActivity";
 /* public AnimationDrawable animationDrawable;
  public ImageView iv;*/
 public TextView textview;
 IntentFilter intentFilter;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  Log.e(TAG, "onCreate: ");
  //设置无标题
  requestWindowFeature(Window.FEATURE_NO_TITLE);
  //设置全屏
  ??????getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
  getWindow().getDecorView().setSystemUiVisibility(10);
  setContentView(R.layout.activity_main);
  textview=(TextView)findViewById(R.id.textview);
  intentFilter = new IntentFilter();
  intentFilter.addAction("com.example.startproject"); //为BroadcastReceiver指定action，即要监听的消息名字。
 }

 private BroadcastReceiver StartProjectBroadcastReceive =new BroadcastReceiver() {
  @Override
  //Once boot completed,start server
  public void onReceive(Context context, Intent intent)
  {
Log.e(TAG, "onReceive: ");
//textview.setText("received broadcast!");
runOnUiThread(new Runnable() {
 @Override
 public void run() {
  textview.setText("received broadcast!");
 }
});
  }
 };

 @Override
 protected void onStart() {
  // TODO Auto-generated method stub
  super.onStart();
  Log.e(TAG, "onStart: ");
  registerReceiver(StartProjectBroadcastReceive,intentFilter); //注册监听
 }
 @Override
 protected void onStop() {
  // TODO Auto-generated method stub
  super.onStop();
  Log.e(TAG, "onStop: ");
  unregisterReceiver(StartProjectBroadcastReceive); //取消监听
 }


 @Override
 public void onDestroy() {
  super.onDestroy();
  System.gc();
 }
}

终端下：adb shell am broadcast -a "com.example.startproject" 查看效果

这个例子是动态注册广播，下面介绍一下 Android广播机制。
