• android 发送自定义广播以及接收自定义广播


    发送自定义广播程序:

    布局文件:

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                  android:orientation="vertical"
                  android:layout_width="fill_parent"
                  android:layout_height="fill_parent"
            >
        <Button
                android:onClick="send"
                android:text="点击发送广播"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"/>
    </LinearLayout>

    activity.java:

    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    
    public class MyActivity extends Activity {
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
        }
    
        public void send(View view) {
            //创建一个意图(装载广播事件)
            Intent intent = new Intent();
            intent.setAction("com.wuyou.something");
            //发送无序广播
            sendBroadcast(intent);
        }
    }

    接收自定义广播程序:

    在AndroidManifest.xml中配置广播接收者:

            <receiver android:name=".MyBroadcastReceiver">
                <intent-filter>
                    <action android:name="com.wuyou.something"></action>
                </intent-filter>
            </receiver>
    import android.content.BroadcastReceiver;
    import android.content.Context;
    import android.content.Intent;
    import android.widget.Toast;
    
    /**
     * Created by Heyiyong on 14-1-4 上午10:59.
     */
    public class MyBroadcastReceiver extends BroadcastReceiver {
        public void onReceive(Context context, Intent intent) {
            Toast.makeText(context, "收到自定义的广播", 1).show();
        }
    }
