因为有两种获取大小的方法。从API级别13以上,此方法适用于我
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
低于14这个方法对我有用
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth(); // deprecated
int height = display.getHeight(); // deprecated
我可以获得所有API级别的屏幕尺寸吗? 请帮助我。

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;

支持所有版本的android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();
}

public void ScreenSize()
{
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();
}
}

试试这段代码,用于显示屏幕规格:
此示例在API 8上进行了测试,您可以轻松了解Display Matrix ...希望这有助于
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags( WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN );
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);

tv.setText("The screen size is:"+Math.sqrt(height*height+width*width));
