Android获取屏幕宽度的4种方法

方法一：

		WindowManager wm = (WindowManager) this
				.getSystemService(Context.WINDOW_SERVICE);
		int width = wm.getDefaultDisplay().getWidth();
		int height = wm.getDefaultDisplay().getHeight();

方法二：

		WindowManager wm1 = this.getWindowManager();
		int width1 = wm1.getDefaultDisplay().getWidth();
		int height1 = wm1.getDefaultDisplay().getHeight();

方法一与方法二获取屏幕宽度的方法类似，只是获取WindowManager 对象时的途径不同。

方法三：

		WindowManager manager = this.getWindowManager();
		DisplayMetrics outMetrics = new DisplayMetrics();
		manager.getDefaultDisplay().getMetrics(outMetrics);
		int width2 = outMetrics.widthPixels;
		int height2 = outMetrics.heightPixels;

方法四：

		Resources resources = this.getResources();
		DisplayMetrics dm = resources.getDisplayMetrics();
		float density1 = dm.density;
		int width3 = dm.widthPixels;
		int height3 = dm.heightPixels;
