Broadcast实现开机启动界面

Posted 2020-07-29

**
 * 实现开机启动
 * (1)注册授权： 在清单文件中注册开机启动授权-RECEIVE_BOOT_COMPLETED
 *                 <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
 * 
 * (2)    在广播接收者中设置意图过滤器中
 *         设置action android.intent.action.Boot_COMPLETED
 *            categeory Home
 *         <receiver android:name="com.example.mybroadcastreceiverdemo05_start_up.StartBootCompleted">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
                <category android:name="android.intent.category.HOME"/>
            </intent-filter>       
        </receiver>

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);  
    }
}

//自定义广播接收者，因为本次使用的注册签单文件
public class StartBootCompleted extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent i = new Intent(context, MainActivity.class);
  　　　　//设置标志位，Intent.FLAG_ACTIVITY_NEW_TASK，跳转到一个新的activity
    　  i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
　　     context.startActivity(i);
    }

}

注册广播接收者  

<receiver android:name="com.example.mybroadcastreceiverdemo05_start_up.StartBootCompleted" >
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
