BroadcastReceiver广播

BroadcastReceiver广播

广播类型:普通、有序  简单的举个例子，大体用法思路已经很清楚了，剩下的有时间在附上

实现：注册--->触发--->响应

public class MainActivity extends Activity{ 
    private final String ACTION_NAME = "com.mengle.20150521";
    private Button execute;
      
    protected void onCreate(Bundle savedInstanceState){  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);
        
        execute = (Button) findViewById(R.id.execute);

        // 注册广播
        registerBoradcastReceiver();
          
        execute.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(ACTION_NAME);
                intent.putExtra("mengle", "要发送的内容>>我来了...");
                // 发送广播
                sendBroadcast(intent);
            }
        });  
    }

    public void registerBoradcastReceiver() {
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(ACTION_NAME);
        // 注册广播
        registerReceiver(mBroadcastReceiver, intentFilter);
    }

    private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            String str = intent.getStringExtra("mengle");
            if (action.equals(ACTION_NAME)) {
                Toast.makeText(MainActivity.this, str, 1000).show();
            }
        }
    };

}
