如何在Android中隐藏状态栏

Question

我提到了这个链接。在这种情况下，如果用户单击EditText（对于ex To：），将弹出键盘，同时用户可以滚动查看所有剩余的视图（例如：compose，subject，send按钮）。该屏幕。同样，在我的应用程序中，我有一个活动，就是我有一些小部件或视图。假设如果用户单击“我的活动”中的Edittext，则弹出键盘，并且我可以滚动查看其余视图。但是，如果我android:theme="@android:style/Theme.NoTitleBar.Fullscreen"在清单中指定此属性，则无法滚动以查看其余视图，但是如果Give属性android:theme="@android:style/Theme.NoTitleBar"这样，我可以在清单中滚动查看剩余的视图，但是该屏幕上有状态栏，这里我要全屏显示，即使弹出键盘，也可以滚动查看剩余的视图..？为此我需要做哪些更改？

将此添加到您的活动类@Overrideprotected void onCreate(Bundle savedInstanceState) {&nbsp; &nbsp; super.onCreate(savedInstanceState);&nbsp; &nbsp; requestWindowFeature(Window.FEATURE_NO_TITLE);&nbsp; &nbsp; this.getWindow().setFlags(&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; WindowManager.LayoutParams.FLAG_FULLSCREEN,&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; WindowManager.LayoutParams.FLAG_FULLSCREEN);&nbsp; &nbsp; setContentView(R.layout.activity_main);&nbsp; &nbsp; // some your code}
