點擊對話框中的editext框。隱式鍵盤必須隱藏

Question

我在對話框上有一個edittextbox。當我點擊editext框時，鍵盤必須被禁用。

在這裏，我有下面的代碼，編輯tetxtbox是pressent。

Answer 1

隱藏鍵盤使用

InputMethodManager imm = (InputMethodManager)getSystemService(
    Context.INPUT_METHOD_SERVICE); 
    imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0); 

您也可以嘗試在監聽器設置它，所以它不是在對話框本身叫做：

dialog.setOnShowListener(new OnShowListener() { 
@Override 
public void onShow(DialogInterface dialog) { 
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); 
    imm.showSoftInput(textEdit, InputMethodManager.SHOW_IMPLICIT); 
} 
}); 

Answer 2

嘗試以下代碼：

InputMethodManager im=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); 
im.hideSoftInputFromWindow(yourEditText.getWindowToken(), 0);
