java - Android 中的警报框不起作用

Question

该代码无法运行。请帮我。它打印替换所有字符串，但进一步的代码未运行。

当我调试这个时，代码中没有错误。它将显示警报框的代码。

if(count>0)

          {
              System.out.println("replace all string name ");
                 // final Intent intent_ul=new Intent(this, UploadExcel.class);
              AlertDialog.Builder alertDialogBuilder_ue = new AlertDialog.Builder(this);            
                 alertDialogBuilder_ue.setTitle("Alert!!");
                 alertDialogBuilder_ue
                    .setMessage("Are you sure you want to Replace all the data related to this style ? ")

                    .setCancelable(false)
                    .setPositiveButton("Yes",new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,int id) {
                             mySQLiteAdapter.openToWrite();
                              mySQLiteAdapter.delete_style_measurement(style_no);
                              Log.d("","yes click");
                              count=0;
                              mySQLiteAdapter.close();

                        }
                    })
                    .setNegativeButton("No",new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,int id) {
                            Log.d("","No click");
                            count++;
                            dialog.cancel();
                            // startActivity(intent_ul);
                             //finish();
                        }
                    });
          }

在 if 条件末尾添加这些行

 AlertDialog alertDialog = alertDialogBuilder_ue.create();
 alertDialog.show();
