AlertDialog自定義佈局按鈕不可點擊

Question

我試圖在AlertDialog類中創建一個登錄按鈕。我正在用按鈕膨脹自定義佈局。

問題是按鈕什麼也不做。代碼編譯，沒有錯誤，只是不可點擊

這是我的課。

public class LoginDialogFragment extends DialogFragment { 

@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 

    // Use the Builder class for convenient dialog construction 
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 

    //create inflater 
    LayoutInflater inflater = getActivity().getLayoutInflater(); 

    //set view with inflater 
    final View dialogView = inflater.inflate(R.layout.login_dialog, null); 
    builder.setView(inflater.inflate(R.layout.login_dialog, null)); 

    //set dialog to be non-cancelable 
    setCancelable(false); 

    final Dialog alertDialog = builder.create(); 

    //remove title bar 
    alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 

    //get editText fields to set font 
    EditText editUser = (EditText) dialogView.findViewById(R.id.user); 
    EditText editPass = (EditText) dialogView.findViewById(R.id.pass); 
    EditText editIp = (EditText) dialogView.findViewById(R.id.ip_addr); 
    Button login = (Button) dialogView.findViewById(R.id.login_button); 

    //get the font 
    Typeface typeFace = Typeface.createFromAsset(getContext().getAssets(), "fonts/arial.ttf"); 

    //set the font 
    editIp.setTypeface(typeFace); 
    editPass.setTypeface(typeFace); 
    editUser.setTypeface(typeFace); 

    //set background and no dim affect 
    alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(0)); 
    alertDialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND); 

    //create onClick listener 
    login.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Toast.makeText(getActivity(), "message", Toast.LENGTH_LONG).show(); 

     } 
    }); 

    // Create the AlertDialog object and return it 
    return alertDialog; 
}

Answer 1

這就是問題所在：

final View dialogView = inflater.inflate(R.layout.login_dialog, null); 
builder.setView(inflater.inflate(R.layout.login_dialog, null)); 

你兩次膨脹的觀點，而不是在對話框中點擊監聽器設置爲視圖。

做這樣的：

final View dialogView = inflater.inflate(R.layout.login_dialog, null); 
builder.setView(dialogView);
