Android 代码片段(一)

1、获取屏幕宽/高(一)

public static Point getDisplaySize(Context context) {
WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
Point size = new Point();
display.getSize(size);
return size;
}
Point size = getDisplaySize(this);
int width = size.x;
int height = size.y;2、获取屏幕宽/高(二)
DisplayMetrics metric = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metric);
int mScreenWidth = metric.widthPixels;
int mScreenHeight = metric.heightPixels;
float mDensity = metric.density;
