首先我们需要设置权限
<uses-permission android:name="android.permission.WAKE_LOCK" />
然后动态注册广播:
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
registerReceiver(new AlarmClockReceiver(), filter);
广播接受接处理(AlarmClockReceiver
)
public class AlarmClockReceiver extends BroadcastReceiver {
private String TAG="hyc";
@Override
public void onReceive(Context context, Intent intent) {
if (Intent.ACTION_SCREEN_ON==intent.getAction()){//亮屏
Intent startPhone = new Intent(context, PhotoActivity.class);
startPhone.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(startPhone);
Log.d(TAG, "onReceive:on ");
}else if (Intent.ACTION_SCREEN_OFF==intent.getAction()){//灭屏
Log.d(TAG, "onReceive:off ");
}
}
}
广播与服务的清单文件如下:
<service
android:name=".RemindService"
android:enabled="true"
android:exported="true" />
<receiver
android:name=".AlarmClockReceiver"
android:enabled="true"
android:exported="true"
/>
我们需要展示的Activity需要进行的操作
public class PhotoActivity extends AppCompatActivity {
@SuppressLint("InvalidWakeLockTag")
private PowerManager.WakeLock wl;
@SuppressLint("InvalidWakeLockTag")
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_phone);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1) {
setShowWhenLocked(true);
}else{
//页面悬浮于锁屏之上
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
//亮屏
KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
KeyguardManager.KeyguardLock kl = km.newKeyguardLock("unlock");
kl.disableKeyguard();
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.FULL_WAKE_LOCK, "bright");
wl.acquire();
}
}
@Override
protected void onDestroy() {
super.onDestroy();
if (wl!=null){
wl.release();
}
}
}
