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" />
