Android-PickerView

很实用的仿IOS选择器库
在使用过程中与国产部分手机虚拟导航按键有重叠问题
以时间选择器为例：

var timePicker= TimePickerBuilder(this, OnTimeSelectL ...(该处省略)
//适配方法 kotlin
var layoutParams:FrameLayout.LayoutParams= timePicker.dialogContainerLayout.layoutParams as FrameLayout.LayoutParams
layoutParams.bottomMargin=UIHelper.getNavigationBarHeight(activity)
timePicker.dialogContainerLayout.layoutParams=layoutParams

timePicker.show()

UIHelper.getNavigationBarHeight(activity) 是写的一个获得手机虚拟导航按键高度的方法
getNavigationBarHeight(...)如下：

/**
 * 获得NavigationBar的高度
 */
public static int getNavigationBarHeight(Activity activity) {
    int result = 0;
    Resources resources = activity.getResources();
    int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
    if (resourceId > 0 && checkHasNavigationBar(activity)) {
        result = resources.getDimensionPixelSize(resourceId);
    }
    return result;
}

/**
 * 判断是否有NavigationBar
 * @param activity
 * @return
 */
public static boolean checkHasNavigationBar(Activity activity) {
    WindowManager windowManager = activity.getWindowManager();
    Display d = windowManager.getDefaultDisplay();
    DisplayMetrics realDisplayMetrics = new DisplayMetrics();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        d.getRealMetrics(realDisplayMetrics);
    }
    int realHeight = realDisplayMetrics.heightPixels;
    int realWidth = realDisplayMetrics.widthPixels;
    DisplayMetrics displayMetrics = new DisplayMetrics();
    d.getMetrics(displayMetrics);
    int displayHeight = displayMetrics.heightPixels;
    int displayWidth = displayMetrics.widthPixels;
    return (realWidth - displayWidth) > 0 || (realHeight - displayHeight) > 0;
}

当然还有别的适配方法，这种方法来的比较直接，不喜勿喷哈
