Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth(); // deprecated
int height = display.getHeight(); // deprecated
14岁以下,这种方法对我有效
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth(); // deprecated
int height = display.getHeight(); // deprecated
我可以得到所有API级别的屏幕大小吗???
请帮助我。要支持所有版本的android,请使用下面的代码
int Measuredwidth = 0;
int Measuredheight = 0;
Point size = new Point();
WindowManager w = getWindowManager();
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2){
w.getDefaultDisplay().getSize(size);
Measuredwidth = size.x;
Measuredheight = size.y;
}else{
Display d = w.getDefaultDisplay();
Measuredwidth = d.getWidth();
Measuredheight = d.getHeight();
}
试试这个家伙
int density;
private DisplayMetrics metrics;
private int widthPixels;
private float scaleFactor;
private float widthDp;
private DisplayMetrics metrics;
metrics = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics);
density= getResources().getDisplayMetrics().densityDpi;
widthPixels = metrics.widthPixels;
scaleFactor = metrics.density;
widthDp = widthPixels / scaleFactor;
请尝试此代码,我用于显示屏幕规格: 这个例子在API 8上测试过,你可以很容易地理解显示矩阵。。。希望这有帮助

显示=((WindowManager)getSystemService(Context.WINDOW\u服务))
.getDefaultDisplay()
这段代码对我很管用。试试吧。根据设备的API使用这两种方法即可。将向您展示如何这样做。
int w = display.getWidth();
int h = display.getHeight();
