Android 设置后台静态广播和activity进行通信

一：注册设置后台静态广播

import android.app.Activity; import android.content.BroadcastReceiver; import android.content.Context; 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; import android.widget.TextView; public class MainActivity extends Activity { private Button mButton; private TextView mTextView; public static String ACTION_INTENT_TEST = "com.demo.test"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTextView = (TextView) findViewById(R.id.message_tv); mButton = (Button) findViewById(R.id.send_btn); mButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Intent mIntent = new Intent(ACTION_INTENT_TEST); sendBroadcast(mIntent); } }); registerMessageReceiver(); } //在销毁时要与广播解绑 @Override protected void onDestroy() { unregisterReceiver(mMessageReceiver); super.onDestroy(); } public MessageReceiver mMessageReceiver; public static String ACTION_INTENT_RECEIVER = "com.demo.receiver"; /** * 动态注册广播 */ public void registerMessageReceiver() { mMessageReceiver = new MessageReceiver(); IntentFilter filter = new IntentFilter(); filter.addAction(ACTION_INTENT_RECEIVER); registerReceiver(mMessageReceiver, filter); } public class MessageReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub if (intent.getAction().equals(ACTION_INTENT_RECEIVER)) { mTextView.setText(intent.getStringExtra("message")); } } } } 二：自定义广播接收器 import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.util.Log; public class MyBroadCast extends BroadcastReceiver{ public MyBroadCast() { Log.v("BROADCAST_TAG", "MyBroadCast"); } @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub Log.v("BROADCAST_TAG", "onReceive"); Bundle bundle = intent.getExtras(); if(intent.getAction().equals(MainActivity.ACTION_INTENT_TEST)) { processCustomMessage(context, bundle); } } //send msg to MainActivity private void processCustomMessage(Context context, Bundle bundle) { Intent mIntent=new Intent(MainActivity.ACTION_INTENT_RECEIVER); mIntent.putExtra("message", "测试Broadcast与Activity之间的通信"); context.sendBroadcast(mIntent); } } 三：配置注册静态广播 <receiver android:name=".MyBroadCast"> <intent-filter > <action android:name="com.demo.test"/> </intent-filter> </receiver>
