If you want the display dimensions in pixels you can use this code:

如果您想要显示尺寸(以像素为单位),可以使用以下代码:

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();
int height = display.getHeight();

Then you can add condition that compares the height to satisfy your needs.

然后,您可以添加比较高度的条件以满足您的需求。

In inches:

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
double x = Math.pow(dm.widthPixels/dm.xdpi,2);
double y = Math.pow(dm.heightPixels/dm.ydpi,2);
double screenInches = Math.sqrt(x+y);
Log.d("debug","Screen inches : " + screenInches);

From within activity:

从活动内部:

int width = getWindowManager().getDefaultDisplay().getWidth();
int height = getWindowManager().getDefaultDisplay().getHeight();

Or if you only have Context object:

或者如果您只有Context对象:

WindowManager windowManager = (WindowManager)mContext.getSystemService(WINDOW_SERVICE);
int width = windowManager.getDefaultDisplay().getWidth();
int height = windowManager.getDefaultDisplay().getHeight()
