注意声明自定义权力
<permission android:name="com.example.wkp.broadcast.MY_PEMISSION"/>
开启权力
<uses-permission android:name="com.example.wkp.broadcast.MY_PEMISSION"></uses-permission>
静态注册
<receiver android:name=".MyReceiver2"> <intent-filter> <action android:name="com.example.wkp.broadcast.MY_ACTION"/> </intent-filter></receiver>
package com.example.wkp.broadcast; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.util.Log; /** * Created by wkp on 2016/9/21. */ public class MyReceiver2 extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { Log.v("hh","get broadcast"); } }
MyReceiver2.java
接收器
package com.example.wkp.broadcast; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.view.View; import android.widget.Button; /** * Created by wkp on 2016/9/21. */ public class SecondActivity extends Activity { private Button btn=null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_second); btn= (Button) findViewById(R.id.send); btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent=new Intent(); intent.setAction("com.example.wkp.broadcast.MY_ACTION"); sendBroadcast(intent,"com.example.wkp.broadcast.MY_PEMISSION"); Log.v("hehe","already send"); } }); } }
SecondActivity.java
点击按钮发送广播
有序广播先定义先接收
abortBroadcast();忽略广播
可以通过android:priority制定优先级 不写为0
可以设置是否接收其他app的广播
可以设置是否被其他app接收广播 本地广播LocalBroadcastManager
private LocalBroadcastManager manager= LocalBroadcastManager.getInstance(this);
LocalReceiver receiver=new LocalReceiver();
IntentFilter filter=new IntentFilter();
filter.addAction("com.example.wkp.broadcast.MY_ACTION");
manager.registerReceiver(receiver,filter);
