設置android自動彈出軟件盤

//需要異步調用   editText爲EditText的id   也是用於PopupWindow的軟鍵盤 彈出
  Handler handle = new Handler();
        handle.postDelayed(new Runnable() {
            @Override
            public void run() {
                InputMethodManager inputMethodManager = (InputMethodManager) editText.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
                inputMethodManager.showSoftInput(editText, 0);
            }
        }, 0);
