我正在嘗試使用主密鑰鎖https://github.com/shaobin0604/Android-HomeKey-Locker 我希望能夠檢測並阻止主屏按鈕單擊鎖定屏幕。大部分答案都提到它不能被禁用。獲取類型爲attr的錯誤預期資源
這是HomeKeyLocker類:
package com.example.harshilshah.screenonoff;
import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.Gravity;
import android.view.MotionEvent;
import android.view.WindowManager;
import android.widget.FrameLayout;
import static android.view.WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL;
import static android.view.WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED;
import static android.view.WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
public class HomeKeyLocker {
private OverlayDialog mOverlayDialog;
public void lock(Activity activity) {
if (mOverlayDialog == null) {
mOverlayDialog = new OverlayDialog(activity);
mOverlayDialog.show();
}
}
public void unlock() {
if (mOverlayDialog != null) {
mOverlayDialog.dismiss();
mOverlayDialog = null;
}
}
public static class OverlayDialog extends AlertDialog {
public OverlayDialog(Activity activity) {
super(activity, R.style.OverlayDialog);
WindowManager.LayoutParams params = getWindow().getAttributes();
params.type = TYPE_SYSTEM_ERROR;
params.dimAmount = 0.0F; // transparent
params.width = 0;
params.height = 0;
params.gravity = Gravity.BOTTOM;
getWindow().setAttributes(params);
getWindow().setFlags(FLAG_SHOW_WHEN_LOCKED | FLAG_NOT_TOUCH_MODAL, 0xffffff);
setOwnerActivity(activity);
setCancelable(false);
}
public final boolean dispatchTouchEvent(MotionEvent motionevent) {
return true;
}
protected final void onCreate(Bundle bundle) {
super.onCreate(bundle);
FrameLayout framelayout = new FrameLayout(getContext());
framelayout.setBackgroundColor(0);
setContentView(framelayout);
}
}
}
這是styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
</style>
<style name="OverlayDialog" parent="@android:style/Theme.Dialog">
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowFrame">@null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowIsTranslucent">false</item>
<item name="android:backgroundDimEnabled">false</item>
</style>
</resources>
我收到類型attr的錯誤預期的資源在以下行
public OverlayDialog(Activity activity) {
super(activity, R.style.OverlayDialog);//ERROR
我該如何解決這個問題?
