XML is not dynamic. Screen measurements have to be done in Java during onCreate.

XML不是动态的。屏幕测量必须在onCreate期间用Java完成。

 Display display = getWindowManager().getDefaultDisplay();
    Point size = new Point(); display.getSize(size);
    int width=size.x; int height=size.y;

LinearLayout.LayoutParams params= new LinearLayout.LayoutParams(width,width);
yourView.setLayoutParams(params);

find width of your layout programmatically, and set that value as height of your layout.

以编程方式查找布局的宽度,并将该值设置为布局的高度。

//get Width
int width=layout.getWidth();

//set height
layout.getLayoutParams().height=width;

#3

should be like this,if you want height for full screen use match_parent also

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"

/>
