android - 警报对话框生成器确认按钮

Question

在我的应用程序中，我使用了警报对话框生成器来单击按钮。因此，当我按下按钮时，会打开一个小弹出窗口，其中包含选项 - 激活和停用。那么，当用户按下“激活”或“停用”时，我可以做到这一点吗？确认窗口会打开，并带有问题“您确定吗？”以及选择是或否？？

我在另一个对话框中创建了对话框。

查看这段代码:

twsbiSelectionMenuDialog = new Dialog(this,R.style.CustomDialogTheme);
            twsbiSelectionMenuDialog.setContentView(R.layout.twsbi_selection_menu_dialog);
            twsbiSelectionMenuDialog.setCancelable(true);
            twsbiSelectionMenuDialog.setCanceledOnTouchOutside(true);
            
            // To Open new Canvas ===================================
            Button newLayoutButton = (Button) twsbiSelectionMenuDialog.findViewById(R.id.newLayoutButton);
            newLayoutButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    twsbiSelectionMenuDialog.dismiss();
                    // AlertDialog for confirmation
                    AlertDialog.Builder clearConfirmDialog = new AlertDialog.Builder(TWSBIDrawMainActivity.this);
                    clearConfirmDialog.setMessage("Do you want to clear this and open new canvas ?").setCancelable(false)
                    .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            // Action for 'Yes' Button
                            myView = new MyView(TWSBIDrawMainActivity.this);
                            takePhotoFromCamera = false;
                            takePhotoFromGallery = false;
                            canvasColor = 0xFFFFFFFF;
                            drawingLayout.removeView(myView);
                            drawingLayout.addView(myView);
                        }
                    })
                    .setNegativeButton("No", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            //  Action for 'NO' Button
                            dialog.cancel();
                        }
                    });
                    AlertDialog alert = clearConfirmDialog.create();
                    alert.setTitle("Draw");
                    alert.setIcon(R.drawable.app_icon);
                    alert.show();
                }
            });
            
            // For canvas Color Selection ===================================
            Button canvasColorButton = (Button) twsbiSelectionMenuDialog.findViewById(R.id.canvasColorButton);
            canvasColorButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    twsbiSelectionMenuDialog.dismiss();
                    pickColour(); // to pick colour
                }
            });

只需引用您的情况即可，它会对您有所帮助。
