用户使用for循环和提示对话框输入的内容显示了不同的行为 [英] input from user using for loop and prompt dialogue box shows different behaviour

问题描述

我使用下面的代码在android应用中获取用户输入.它运行正常，但经过几次尝试我发现的是那样. 下面的方法从for循环中调用以获取不同的值.

i used the code below to get user input in android app. it runs fine but what i found after several attempts is that. the method below is called from a for loop to get different values.

1. 代码以相反的顺序接受输入，即它必须先获取x的值，然后获取y的值.在应用程序上时，系统要求我输入y的值，然后输入x.

1. The code takes input in reverse order i.e it has to take value for x and then y. while on the app i am asked to enter value of y and then x.

它不等待用户输入，它显示对话框，但继续运行整个程序.因为当我输入任何值时都不会做任何更改.

it doesnot wait for the user input it shows the dialogue box but keeps on running the whole program. as when i enter any value doesnt make any changes as it has to do.

我认为对话框的反向顺序也是出于相同的原因，即第二个对话框与第一个对话框重叠.

what i believe is that the reverse order of dialogue boxes is also from the same reason that the second dialogue box overlaps the first one.

如何使它停止，除非用户输入任何数据然后继续前进? 同样，当我从代码中的编辑框中删除final时，它给出了错误，请使用remove视图，因为这个孩子已经有一个父级了.

how do i make it stop unless user enter any data and then move forward? also when i remove final from the editbox in the code, it gives error the please use remove view because this child already has a parent etc.

下面提供了代码

void var_init(String to_match,String[][] temp) {

    String t_match=to_match;
//problem in the below line


    AlertDialog.Builder builder = new AlertDialog.Builder(RuleEngine.this);
    builder.setTitle("Enter Value for"+t_match);

// Set up the input
    final EditText input = new EditText(RuleEngine.this);

    builder.setView(input);

// Set up the buttons
    builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
           t_replace = input.getText().toString();
        }
    });
    builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    });

    builder.show();

推荐答案

它是因为对话框每次迭代都相互重叠.实际上，x排在第一位，但与y对话框重叠.一种异步行为，尝试找到其他方法.

Its becasue the dialogue boxes overlaps each other with every iteration. in reality the x is coming first but overlapped by the y dialogue box. an as async behaviour try to find other way around.
