Android隐藏和禁用通知(状态)栏

Question

通过使用下面的代码,我可以通过全屏隐藏通知栏

android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen"

要么

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

但我想要做的是完全禁用状态栏.我正处于所谓的"自助服务终端模式",我想确保用户不能从顶部挡板上滑下手指.上述两种解决方案都可以隐藏通知栏,但它不适用于在应用程序中完全禁用它.

这可能吗？

Answer 1

而不是跟随其他答案的链接,这是我做的.

如果下拉(即使在全屏幕应用程序中),此解决方案也不允许用户"查看"处于"预览"状态的状态栏,但它不允许用户将状态栏拉到其完整状态以查看设置,通知等

您必须先在您的帐户中添加权限 AndroidManifest.xml

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/> 

然后添加另一个被调用的类(Java文件)customViewGroup.java并将此代码放入其中:

import android.content.Context;
import android.util.Log;
import android.view.MotionEvent;
import android.view.ViewGroup;

public class customViewGroup extends ViewGroup {
    public customViewGroup(Context context) {
        super(context);
    }
    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b) {
    }
    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        Log.v("customViewGroup", "**********Intercepted");
        return true;
    }
}

完成这两项设置后,您可以将其添加到主体中 onCreate()

WindowManager manager = ((WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE));
WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams();
localLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
localLayoutParams.gravity = Gravity.TOP;
localLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|
// this is to enable the notification to recieve touch events
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
// Draws over status bar
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;
localLayoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
localLayoutParams.height = (int) (50 * getResources().getDisplayMetrics().scaledDensity);
localLayoutParams.format = PixelFormat.TRANSPARENT;
customViewGroup view = new customViewGroup(this);
manager.addView(view, localLayoutParams);

此解决方案禁用始终向下拉状态栏的功能,直到您的应用关闭.如果您不想每次都关闭应用,则必须在暂停时删除此操作.
