第一步是获取设备本身的屏幕高度和宽度,然后根据需要拉伸/收缩或填充位图。这个SO 答案的来源应该有所帮助,复制如下。向约瑟夫提供原始答案的道具。
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();
这是获取方向的通用来源。
int orientation = display.getOrientation();
或来自这里的更多相关来源(有点混乱但看起来正确)。
public int getscrOrientation()
{
Display getOrient = getWindowManager().getDefaultDisplay();
int orientation = getOrient.getOrientation();
// Sometimes you may get undefined orientation Value is 0
// simple logic solves the problem compare the screen
// X,Y Co-ordinates and determine the Orientation in such cases
if(orientation==Configuration.ORIENTATION_UNDEFINED){
Configuration config = getResources().getConfiguration();
orientation = config.orientation;
if(orientation==Configuration.ORIENTATION_UNDEFINED){
//if height and widht of screen are equal then
// it is square orientation
if(getOrient.getWidth()==getOrient.getHeight()){
orientation = Configuration.ORIENTATION_SQUARE;
}else{ //if widht is less than height than it is portrait
if(getOrient.getWidth() < getOrient.getHeight()){
orientation = Configuration.ORIENTATION_PORTRAIT;
}else{ // if it is not any of the above it will defineitly be landscape
orientation = Configuration.ORIENTATION_LANDSCAPE;
}
}
}
}
return orientation; // return value 1 is portrait and 2 is Landscape Mode
}
