在 Android 开发中检查什么样的设备是非常不准确的。试试我的代码
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;
}
