如何在第一號對話框上調用removeView（）以顯示第二號對話框

Question

我正在使用一個涉及對話框的應用程序，該對話框應該一個接一個地出現。 我的意思是，當我單擊第一個對話框的肯定按鈕時，它應該隨后彈出另一個第二個對話框。 我面臨的問題是第二個對話框，第二個對話框不會彈出，並導致應用程序崩潰。

我收到一條錯誤消息：“ java.lang.IllegalStateException：指定的子代已經有一個父代。您必須首先在該子代的父代上調用removeView（）。”

public static void showBusinessOrPrivateStartDialog(final Context context, final CallLogEntry call)
       {
          if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
          {
             // If new version of android, then check permission
             if (!Settings.canDrawOverlays(context))
             {
                Log.e(TAG, "Permission Denied: Draw overlays (for popup)");
                return;
             }
          }

          LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
          //View view = inflater.inflate(R.layout.dialog_call_type, null);

          AlertDialog.Builder builder = new AlertDialog.Builder(context, Theme_Material_Light_Dialog_Alert);

          builder.setTitle("Was this a private or a business call?");
          builder.setMessage("Please select a call type");
          builder.setIcon(R.drawable.ic_deviceinsight);
          builder.setCancelable(true);
          //builder.setView(view);

          builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
             @Override
             public void onCancel(DialogInterface dialog) {
                // Occurs when user cancels the dialog, or clicks somewhere else in the screen or presses the back button
                Log.i(TAG, "cancelled");

                saveCallEntry(context, call, CLASSIFICATION_TYPE_BUSINESS, "", true, "");
             }
          });

          builder.setPositiveButton("Business", new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog, int which) {
                CallClassification.showBusinessCallPopup(context, call);
             }
          });
          builder.setNegativeButton("Private", new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog, int which) {
                saveCallEntry(context, call, CLASSIFICATION_TYPE_PRIVATE, "", false, "");
             }
          });

          AlertDialog dialog = builder.create();
          // Rather use something like TYPE_SYSTEM_ALERT, if possible.
          dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT); // TYPE_SYSTEM_ERROR
          dialog.show();
       }

這是第二個對話框的第二種方法，我的應用程序在dialog.show上崩潰

public static void showBusinessCallPopup(final Context context, final CallLogEntry call)
       {
          // NEW NRF
          if (AppPreferences.isNRF(context)) {
             CallItem callItem = saveCallEntry(context, call, CLASSIFICATION_TYPE_BUSINESS, "", false, "");

             // SHOW NEW FORM
             Intent intent = new Intent(context, CallClassificationFormActivity.class);
             intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
             EventBus.getDefault().postSticky(callItem);
             context.startActivity(intent);

             return;
          }

          if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
          {
             // If new version of android, then check permission
             if (!Settings.canDrawOverlays(context))
             {
                Log.e(TAG, "Permission Denied: Draw overlays (for popup)");
                return;
             }
          }

          LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
          View view = inflater.inflate(R.layout.dialog_call_details, null);

          AlertDialog.Builder builder = new AlertDialog.Builder(context, Theme_Material_Light_Dialog_Alert);

          String toOrFrom = call.Type == CallLog.Calls.INCOMING_TYPE ? "from" : "to";

          //builder.setTitle("Business call");
          builder.setCustomTitle(view);
          //builder.setMessage("Please enter reference details for the call " + toOrFrom + " " + call.Number);
          //builder.setIcon(R.drawable.ic_deviceinsight);
          builder.setCancelable(true);
          builder.setView(view);

          final EditText etReference = (EditText)view.findViewById(R.id.etReference);
          final EditText etComment = (EditText)view.findViewById(R.id.etComment);

          builder.setPositiveButton("Confirm", new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog, int which) {

                String reference = etReference.getText().toString();
                String comment = etComment.getText().toString();

                saveCallEntry(context, call, CLASSIFICATION_TYPE_BUSINESS, reference, false, comment);
             }
          });
          builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
             @Override
             public void onCancel(DialogInterface dialog) {
                Log.i(TAG, "cancelled");
             }
          });

          AlertDialog dialog = builder.create();
          dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT); // TYPE_SYSTEM_ERROR
          dialog.show();
       }

這是我的xml。 我在這篇文章中包含了xml，因為我在某處讀到，定義文本框的高度和寬度的方式可能會引起問題。

Answer 1

致電之前

CallClassification.showBusinessCallPopup（context，call）;

你需要打電話

dialog.dismiss（）;

在相同的onClick（）中。

希望這能解決您的情況。

Answer 2

聽到您的經驗后，我可能會想到另一種解決方案。 而不是在每個方法中聲明AlertDialog變量，而是聲明一個全局變量，以便您可以確保在任何實例中僅顯示一個Dialog。

聲明時，使

AlertDialog對話框= null;

然后在課堂上

    showBusinessOrPrivateStartDialog() {
    if(dialog == null) {
    dialog = build.create();
    }
    }


    builder.setPositiveButton("Business", new DialogInterface.OnClickListener() {
          public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                    CallClassification.showBusinessCallPopup(context, call);
                 }
              });

builder.setOnDismissListener(new OnDismissListener() {
public void onDismiss() {
dialog = null;
}
}

然后再次在showBusinessCallPopup（）中，

if(dialog == null) {
    dialog = build.create();
    }

希望這對您有所幫助。

在第二個代碼中，您要兩次添加視圖，也許您應該刪除其中之一。

    builder.setCustomTitle(view); -> Here
    builder.setCancelable(true);
    builder.setView(view); --> Here
