android判断pad还是手机

第一种。

Rect frame = new Rect();
                getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
                if (frame.top == 0) {
                    //tablet 
                } else {
                    //phone
                }

这种要在onCreate走完之后才可以获取。而且不适合设置全屏的项目。

第二种。

public boolean isTablet(Context context) {
    boolean xlarge = ((context.getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == 4);
    boolean large = ((context.getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_LARGE);
    return (xlarge || large);
}

这种除了个别厂商做得特别恶心的设备，都可以判断。

第三种。

File res/values/screen.xml (assuming res/layout/ contains your layout files for handsets)

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <string name="screen_type">phone</string>
</resources>

File res/values-sw600dp/screen.xml (assuming res/layout-sw600dp/ contains your layout files for small tablets like the Nexus 7)

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <string name="screen_type">7-inch-tablet</string>
</resources>

File res/values-sw720dp/screen.xml (assuming res/layout-sw720dp/ contains your layout files for large tablets like the Nexus 10):

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <string name="screen_type">10-inch-tablet</string>
</resources>

简单解释下：在res不同的values下创建不同的screen.xml,这样在不同的设备上取出的String值就不同了，这种比较好用，除了三星某超大屏机器。。。

第四种。

/**
 * Checks if the device is a tablet or a phone
 * 
 * @param activityContext
 *            The Activity Context.
 * @return Returns true if the device is a Tablet
 */
public static boolean isTabletDevice(Context activityContext) {
    // Verifies if the Generalized Size of the device is XLARGE to be
    // considered a Tablet
    boolean xlarge = ((activityContext.getResources().getConfiguration().screenLayout & 
                        Configuration.SCREENLAYOUT_SIZE_MASK) == 
                        Configuration.SCREENLAYOUT_SIZE_XLARGE);

    // If XLarge, checks if the Generalized Density is at least MDPI
    // (160dpi)
    if (xlarge) {
        DisplayMetrics metrics = new DisplayMetrics();
        Activity activity = (Activity) activityContext;
        activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);

        // MDPI=160, DEFAULT=160, DENSITY_HIGH=240, DENSITY_MEDIUM=160,
        // DENSITY_TV=213, DENSITY_XHIGH=320
        if (metrics.densityDpi == DisplayMetrics.DENSITY_DEFAULT
                || metrics.densityDpi == DisplayMetrics.DENSITY_HIGH
                || metrics.densityDpi == DisplayMetrics.DENSITY_MEDIUM
                || metrics.densityDpi == DisplayMetrics.DENSITY_TV
                || metrics.densityDpi == DisplayMetrics.DENSITY_XHIGH) {

            // Yes, this is a tablet!
            return true;
        }
    }

    // No, this is not a tablet!
    return false;
}

和第二种类似，通过屏幕分辨率和像素密度，（貌似）判断的更细一些。。。。

第五种。

TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
        if(manager.getPhoneType() == TelephonyManager.PHONE_TYPE_NONE){
            return "Tablet";
        }else{
            return "Mobile";
        }

这种除了某些pad可以打电话的(貌似不少)，都可以。。。

大概这几个比较可行，没有太好的方案暂时，求讨论求指导。。。。
