Android设备各种使用尺寸整理

// 获取屏幕的宽度、高度 Display defDip = getWindowManager().getDefaultDisplay(); int disWidth = defDip.getWidth(); int disHeight = defDip.getHeight(); Log.i("TAG", "disWidth:" + disWidth + ",disHeight:" + disHeight);

//获取屏幕分辨率 DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); float horiDpi = dm.xdpi; // 屏幕的水平分辨率 float vertDpi = dm.ydpi; // 屏幕的垂直分辨率

// 获得android系统对于目前的屏幕分辨率的分类： int screenSizeClass = dm.densityDpi; Log.i("TAG", "screenSizeClass..." + screenSizeClass); switch (screenSizeClass) { case DisplayMetrics.DENSITY_LOW: // 屏幕属于低分辨率，运行对应的代码 Log.i("TAG", "低分辨率"); break; case DisplayMetrics.DENSITY_MEDIUM: // 中分辨率 Log.i("TAG", "中分辨率"); break; case DisplayMetrics.DENSITY_HIGH: // 高分辨率 Log.i("TAG", "高分辨率"); break; case DisplayMetrics.DENSITY_XHIGH: // 超高分辨率 Log.i("TAG", "超高分辨率"); break; case DisplayMetrics.DENSITY_XXHIGH: Log.i("TAG", "超超高分辨率"); break; default: break; }

 // 判断屏幕尺寸 final int screenSize = getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK; switch (screenSize) { case Configuration.SCREENLAYOUT_SIZE_SMALL: break; case Configuration.SCREENLAYOUT_SIZE_NORMAL: break; case Configuration.SCREENLAYOUT_SIZE_LARGE: break; case Configuration.SCREENLAYOUT_SIZE_XLARGE: // support from API 9 break; case Configuration.SCREENLAYOUT_SIZE_MASK: break; case Configuration.SCREENLAYOUT_SIZE_UNDEFINED: break; default: break; }

1 有一点要注意，必须在AndroidManifest.xml里加上下面的声明 2 3 <supports-screens 4 android:largeScreens="true" 5  android:normalScreens="true" 6  android:resizeable="true" 7  android:smallScreens="true" 8  android:xlargeScreens="true" />
