發送有序廣播

1 單個廣播 觸發

AndroidManifest.xml

<!-- 有序廣播接收器使用的權限 --> <uses-permission android:name="my.permission.receiver"></uses-permission><receiver android:name=".MyReceiver"><intent-filter android:priority="-1000"><action android:name="com.example.androd_8_onderedreceiver_Action_receiver"></action></intent-filter> </receiver>

MainActivity.java

@Override protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);btn1 = (Button)findViewById(R.id.btn1);// 發送有序廣播---靜態注冊btn1.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {Intent intent = new Intent();intent.setAction("xyz.lgch.onderedreceiver_Action_receiver");intent.putExtra("message", "發送有序廣播 www.lgch.xyz");sendOrderedBroadcast(intent, "my.permission.receiver");}}); }

MyReceiver.java

import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.view.Gravity; import android.widget.Toast;// 創建 接收廣播 public class MyReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent arg1) {// TODO Auto-generated method stubString message = "廣播信息" + arg1.getStringExtra("message");Toast toast = Toast.makeText(context, message, 3000);toast.setGravity(Gravity.TOP, 0, 0);toast.show();}}

2 廣播 傳遞 （暫時這么說）

觸發廣播2后，動態廣播接收到參數后 觸發
MainActivity.java

<!-- 發送廣播的自定義權限 --> <permission android:name="my.permission.receiver"></permission><!-- 有序廣播接收器使用的權限 --> <uses-permission android:name="my.permission.receiver"></uses-permission> import android.app.Activity; import android.content.Intent; import android.content.IntentFilter; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button;public class MainActivity extends Activity {Button btn1;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);btn1 = (Button) findViewById(R.id.btn1);// 動態注冊IntentFilter intentFilter = new IntentFilter();intentFilter.addAction("xyz.lgch.onderedreceiver_Action_receiver");intentFilter.setPriority(0);registerReceiver(new MyReceiver5(), intentFilter);// 發送有序廣播---靜態注冊btn1.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {Intent intent = new Intent();intent.setAction("xyz.lgch.onderedreceiver_Action_receiver");intent.putExtra("message", "發送有序廣播 www.lgch.xyz");sendOrderedBroadcast(intent, "my.permission.receiver");}});}}

MyReceiver2.java

import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.view.Gravity; import android.widget.Toast;public class MyReceiver2 extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent arg1) {// TODO Auto-generated method stubString message = "廣播信息:" + arg1.getStringExtra("message");Toast toast = Toast.makeText(context, message, 3000);toast.setGravity(Gravity.TOP, 0, 0);toast.show();Bundle bundle = new Bundle();bundle.putString("aa","666");setResultExtras(bundle);} }

MyReceiver.java

package com.example.testapp;import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.view.Gravity; import android.widget.Toast;public class MyReceiver5 extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent arg1) {Bundle bundle = getResultExtras(true);String data = bundle.getString("aa");String message = "廣播信息" + arg1.getStringExtra("message");Toast toast = Toast.makeText(context, message + "---" + data, 3000);toast.setGravity(Gravity.TOP, 0, 0);toast.show();} }
