Java FrameLayout中setFitsSystemWindows方法的代码示例

当前位置：首页> 代码示例 > Java >正文

```java

import android.widget.FrameLayout; //导入方法依赖的package包/类

/**

* 返回对话框的根视图。我们将其包装在FrameLayout中，因为这是系统通知我们对话框大小已更改的方式。

* 这有一个令人愉快的副作用，即我们不需要在所有模态框前加上 "top: statusBarHeight",

* 因为那个边距将包含在FrameLayout中。

*/

private View getContentView() {

FrameLayout frameLayout = new FrameLayout(getContext());

frameLayout.addView(mHostView);

frameLayout.setFitsSystemWindows(true);

return frameLayout;

}

```
