隐藏和显示状态栏，而对android中的布局没有任何影响 [英] hide and show statusbar without any effect to layout in android

问题描述

我想编写一个通常在全屏模式下运行的读书器应用程序，但是当用户触摸屏幕时，状态栏在我的主布局上可见，而无需重新创建整个视图. 我已经读过这些，但根本没有帮助:

I want to write a book-reader application that normally runs in full-screen, but when user touched screen, status bar become visible OVER my main layout without re-creating the whole view. I already read these but no help at all:

隐藏通知栏而不使用全屏 隐藏通知栏 Android Show活动标题/状态隐藏后顶部上方的栏

知道怎么做吗?

谢谢

推荐答案

最后，我做到了！ 这两种方法将在不破坏布局的情况下显示和隐藏状态栏. 您需要设置

finally, I did it!! these 2 methods will show and hide status bar without destroying the layout. you need to set

private View mMainView; // The main view of the activity

private int mSystemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION;

然后

    /** Hides StatusBar and ActionBar */
private void hideSystemUi() {

    ActionBar ab = getActionBar();
    ab.hide();

    // Set flags for hiding status bar
    int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
    // Hide the status bar.
    mMainView.setSystemUiVisibility(uiOptions);}

和

   /** Shows StatusBar and ActionBar */
private void showSystemUi() {
    ActionBar ab = getActionBar();
    ab.show();
    // Reset flags 
    mMainView.setSystemUiVisibility(this.mSystemUiVisibility);
}

并将其放在您的onCreate()方法中:

and put this in your onCreate() method:

mMainView = findViewById(R.id.mainLayout);
mMainView.setSystemUiVisibility(mSystemUiVisibility);
