对于ProgressDialogs

要防止对话框自动关闭，必须在显示ProgressDialog后设置OnClickListener，如下所示：

connectingDialog = new ProgressDialog(this);

connectingDialog.setCancelable(false);
connectingDialog.setCanceledOnTouchOutside(false);

// Create the button but set the listener to a null object.
connectingDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "Cancel", 
        (DialogInterface.OnClickListener) null )

// Show the dialog so we can then get the button from the view.
connectingDialog.show();

// Get the button from the view.
Button dialogButton = connectingDialog.getButton( DialogInterface.BUTTON_NEGATIVE);

// Set the onClickListener here, in the view.
dialogButton.setOnClickListener( new View.OnClickListener() {

    @Override
    public void onClick ( View v ) {

        // Dialog will not get dismissed until you call dismiss() explicitly.

    }

});

这段代码对你有用，因为我有一个类似的问题，这对我有用。：）

1-重写片段对话框类中的Onstart（）方法。

@Override
public void onStart() {
    super.onStart();
    final AlertDialog D = (AlertDialog) getDialog();
    if (D != null) {
        Button positive = (Button) D.getButton(Dialog.BUTTON_POSITIVE);
        positive.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                if (edittext.equals("")) {
   Toast.makeText(getActivity(), "EditText empty",Toast.LENGTH_SHORT).show();
                } else {
                D.dismiss(); //dissmiss dialog
                }
            }
        });
    }
}

我找到了另一种方法来实现这一点。。。

步骤1：将对话框打开代码放入方法（或C中的函数）。步骤2：在onClick of yes（您的positiveButton）中，调用此对话框打开如果条件不满足，则递归使用方法（通过使用if…else…）。如下所示：

private void openSave() {
   
    final AlertDialog.Builder builder=new AlertDialog.Builder(Phase2Activity.this);

    builder.setTitle("SAVE")
            .setIcon(R.drawable.ic_save_icon)
            .setPositiveButton("Save", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    
                        if((!editText.getText().toString().isEmpty() && !editText1.getText().toString().isEmpty())){

                                createPdf(fileName,title,file);
                            
                        }else {
                            openSave();
                            Toast.makeText(Phase2Activity.this, "Some fields are empty.", Toast.LENGTH_SHORT).show();
                        }

                    
            })
            .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
               dialogInterface.dismiss();
            }
        })
            .setCancelable(false)
            .create()
            .show();

}

但这将使对话框消失片刻，并立即再次出现。：）

这个链接的答案是一个简单的解决方案，它与API 3兼容。它与Tom Bollwitt的解决方案非常相似，但没有使用兼容性较差的OnShowListener。

是的，你可以。您基本上需要：使用DialogBuilder创建对话框show（）对话框在显示的对话框中查找按钮并覆盖其onClickListener

自从我扩展EditTextPreference以来，我对Kamen的代码进行了一些小的修改。

@Override
protected void showDialog(Bundle state) {
  super.showDialog(state);

  class mocl implements OnClickListener{
    private final AlertDialog dialog;
    public mocl(AlertDialog dialog) {
          this.dialog = dialog;
      }
    @Override
    public void onClick(View v) {

        //checks if EditText is empty, and if so tells the user via Toast
        //otherwise it closes dialog and calls the EditTextPreference's onClick
        //method to let it know that the button has been pressed

        if (!IntPreference.this.getEditText().getText().toString().equals("")){
        dialog.dismiss();
        IntPreference.this.onClick(dialog,DialogInterface.BUTTON_POSITIVE);
        }
        else {
            Toast t = Toast.makeText(getContext(), "Enter a number!", Toast.LENGTH_SHORT);
            t.show();
        }

    }
  }

  AlertDialog d = (AlertDialog) getDialog();
  Button b = d.getButton(DialogInterface.BUTTON_POSITIVE);
  b.setOnClickListener(new mocl((d)));
}

真有趣！

});

public class ComentarDialog extends DialogFragment{

               }
           });

    return builder.create();
}

@Override
public void onStart() {
    super.onStart();

    //Obtenemos el AlertDialog
    AlertDialog dialog = (AlertDialog)getDialog();

    dialog.setCanceledOnTouchOutside(false);
    dialog.setCancelable(false);//Al presionar atras no desaparece

    //Implementamos el listener del boton OK para mostrar el toast
    dialog.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if(TextUtils.isEmpty(comentario.getText())){
               Toast.makeText(getActivity(), "Ingrese un comentario", Toast.LENGTH_SHORT).show();
               return;
            }
            else{
                ((AlertDialog)getDialog()).dismiss();
            }
        }
    });

    //Personalizamos
    Resources res = getResources();

    //Buttons
    Button positive_button = dialog.getButton(DialogInterface.BUTTON_POSITIVE);
    positive_button.setBackground(res.getDrawable(R.drawable.btn_selector_dialog));

    Button negative_button =  dialog.getButton(DialogInterface.BUTTON_NEGATIVE);
    negative_button.setBackground(res.getDrawable(R.drawable.btn_selector_dialog));

    int color = Color.parseColor("#304f5a");

    //Title
    int titleId = res.getIdentifier("alertTitle", "id", "android");
    View title = dialog.findViewById(titleId);
    if (title != null) {
        ((TextView) title).setTextColor(color);
    }

    //Title divider
    int titleDividerId = res.getIdentifier("titleDivider", "id", "android");
    View titleDivider = dialog.findViewById(titleDividerId);

    }
}
