android去掉标题栏、信息栏、获取屏幕分辨率、图片全屏

android 中获取屏幕大小的两种方法

　Java代码

　　import android.util.DisplayMetrics;

　　private DisplayMetrics dm;//屏幕分辨率容器

　　dm = new DisplayMetrics();

　　this.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);

　　int width = dm.widthPixels;

　　int height = dm.heightPixels;

　----------------------------------------------------------------------------------------------------------------------------

        Display display = getWindowManager().getDefaultDisplay();

        int width = display.getWidth();

 

        int height = display.getHeight();
