有序广播

abortBroadcast() 终止有序广播的方法 在重写的onReceive的方法里面写

//清单文件 intent-filter设置广播优先级状态 0-1000 优先级越大 越会先收到广播
 <receiver android:name=".MyReceiver">
        <intent-filter android:priority="500">
            <action android:name="com.wuyanzu"/>
            
        </intent-filter>
    </receiver>
        <receiver android:name=".MyReceiver1">
            <intent-filter android:priority="1000">
                <action android:name="com.wuyanzu"/>
            </intent-filter>
        </receiver>
        <receiver android:name=".MyReceiver2">
            <intent-filter android:priority="100">
                <action android:name="com.wuyanzu"/>
            </intent-filter>
        </receiver>

public class MyReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals("com.wuyanzu")){
            String name = intent.getStringExtra("msg");
            Log.e("###", "onReceive: "+name);
        }
    }
}

public class MyReceiver1 extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals("com.wuyanzu")){
            String name = intent.getStringExtra("msg");
            Log.e("###", "onReceive1: "+name);
        }
    }
}

public class MyReceiver2 extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals("com.wuyanzu")){
            String name = intent.getStringExtra("msg");
            Log.e("###", "onReceive2: "+name);
        }
    }
}

  public void dianji(View view) {

        Intent intent=new Intent();
        intent.setAction("com.wuyanzu");
        Bundle bundle=new Bundle();
        bundle.putString("msg","我是吴彦祖");
        intent.putExtras(bundle);
        sendOrderedBroadcast(intent,null);
        sendBroadcast(intent);
    }

输出效果根据优先级分类

粘性广播

// An highlighted block
 public void dianji() {
        Intent intent=new Intent();
        intent.setAction("com.wuyanzu");
        Bundle bundle=new Bundle();
        bundle.putString("msg","我是吴彦祖");
        intent.putExtras(bundle);
        //主要是这个stickybroadcast
        sendStickyBroadcast(intent);
    }

//线程延迟进行跳转就可以先不执行注册方实现延迟收广播的效果 
    public void yanchi(){
        new Thread(
                new Runnable() {
                    @Override
                    public void run() {
                        try {
                            Thread.sleep(5000);
                            Intent intent=new Intent(MainActivity.this,Main2Activity.class);
                            startActivity(intent);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                }
        ).start();
    }
