單擊開發的EditText時鍵盤不顯示

Question

我試圖在我的項目上使用這個有用的庫，但是在使用它並單擊EditText鍵盤沒有顯示，這個簡單的類作為庫部署了EditText

您可以通過添加切換按鈕來強制顯示或隱藏鍵盤

InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
    if (imm.isActive()){
        imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0); // hide
    } else {
        imm.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY); // show
    }
