Android 软键盘不弹出情况

最开始在popupwindow里面无法自动弹出软键盘,后来通过 延时解决此问题

/**
 * 显示键盘
 *
 * @param view
 */
public void showKeyBord(View view) {
    view.postDelayed(() -> KeyBoardUtils.showKeyboard(view), 100);

}

public static void showKeyboard(View view) {
    try {
        InputMethodManager imm = (InputMethodManager) view.getContext()
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm != null) {
            view.requestFocus();
            imm.showSoftInput(view, 0);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }


}
