Android锁屏下显示来电通知界面

1. 新建Activity，并在activity的onCreate()方法中设置flags

@Override

protected void onCreate(Bundle savedInstanceState) {

te(savedInstanceState);

getWindow().addFlags(_DISMISS_KEYGUARD //解锁

| _KEEP_SCREEN_ON //保持屏幕不息屏

| _TURN_SCREEN_ON);//点亮屏幕

if (_INT > 27) {

setShowWhenLocked(true);

} else {

getWindow().addFlags(_SHOW_WHEN_LOCKED);

}

Params params = getWindow().getAttributes();

//低调模式, 会隐藏不重要的状态栏图标，/QQsongQQ/article/details/89312763

UiVisibility = _UI_FLAG_LOW_PROFILE;

getWindow().setAttributes(params);

setContentView(ty_call);

}

2. 在中配置activity，并加入锁屏显示权限

android:screenOrientation="portrait"

android:launchMode="singleInstance"/>

3. 启动Activity

wakeUpAndUnlock(getApplicationContext());

startActivity(new Intent(getApplication(), ).addFlags(_ACTIVITY_NEW_TASK | _ACTIVITY_CLEAR_TOP));

public void wakeUpAndUnlock(Context context) {

//屏锁管理器

KeyguardManager km = (KeyguardManager) temService(RD_SERVICE);

rdLock kl = guardLock("unLock");

//解锁

eKeyguard();

//获取电源管理器对象

PowerManager pm = (PowerManager) temService(_SERVICE);

//获取ck对象,后面的参数|表示同时传入两个值,最后的是LogCat里用的Tag

ck wl = eLock(E_CAUSES_WAKEUP | _DIM_WAKE_LOCK,

//点亮屏幕

e();

//释放

e();

}

注意:覆盖锁屏显示这个功能在某些手机上需要“锁屏显示”权限，目前只能用户自己开启，无法通过代码申请。

附上国内各大厂商跳转到权限的代码
