我需要一些帮助来切换全屏模式。我在首选项屏幕中设置了全屏显示。在我的主要活动的onResume中,我有:
if(mFullscreen == true) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
} else
{
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
但这似乎不起作用,因为它需要在setContentView
之前调用,对吗?
..。但是,我在setContentView
之前使用了requestWindowFeature(Window.FEATURE_NO_TITLE);
,它去掉了标题和状态栏……有人能帮上忙吗?
-编辑-好的,我有一个bug,导致它不能工作。所以它确实是这样的。现在,我只需要知道如何切换标题栏。

else

}
getWindow().setAttributes(attrs);

我的代码在Android2.3和4.4.2上运行良好

自Jellybean (4.1)以来,有了一种不依赖于WindowManager的新方法。与使用WindowManager标志相比,在窗口之外使用setSystemUiVisibility可以对系统栏进行更精细的控制。下面是启用全屏的方法:
if (Build.VERSION.SDK_INT < 16) { //ye olde method
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
} else { // Jellybean and up, new hotness
View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
// Remember that you should never show the action bar if the
// status bar is hidden, so hide that too if necessary.
ActionBar actionBar = getActionBar();
actionBar.hide();
}
下面是如何还原上面的代码:
if (Build.VERSION.SDK_INT < 16) { //ye olde method
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
} else { // Jellybean and up, new hotness
View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_VISIBLE;
decorView.setSystemUiVisibility(uiOptions);
// Remember that you should never show the action bar if the
// status bar is hidden, so hide that too if necessary.
ActionBar actionBar = getActionBar();
actionBar.show();
}
