如果手机从睡眠模式返回,是否可以接收?我需要一个接收器。 OnScreenOn或交互式用于检查屏幕是打开还是关闭。但是我需要确切地知道屏幕何时从睡眠模式返回。安卓API 23及更高版本。
最佳答案
我不知道我是否正确理解您,但似乎您需要BroadcastReceiver
您在this answer中有更多信息
为了完整起见,我在这里添加:
将以下内容添加到清单中:
<receiver android:name=".UserPresentBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.USER_PRESENT" />
<action android:name="android.intent.action.ACTION_SHUTDOWN" />
</intent-filter>
</receiver>
处理动作:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class UserPresentBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent intent) {
/*Sent when the user is present after
* device wakes up (e.g when the keyguard is gone)
* */
if(intent.getAction().equals(Intent.ACTION_USER_PRESENT)){
}
/*Device is shutting down. This is broadcast when the device
* is being shut down (completely turned off, not sleeping)
* */
else if (intent.getAction().equals(Intent.ACTION_SHUTDOWN)) {
}
}
}
