Android的对话框，保持对话框打开时，pressed按钮？ [英] Android Dialog, keep dialog open when button is pressed?

问题描述

我想继续我的对话框打开的时候我preSS的按钮。 目前，它的收盘！请帮帮忙！

  AlertDialog.Builder建设者=新AlertDialog.Builder（本）;

builder.setMessage（你确定要退出吗？）

   .setCancelable（假）
   .setPositiveButton（是，新DialogInterface.OnClickListener（）{
       公共无效的onClick（DialogInterface对话框，INT ID）{
            MyActivity.this.finish（）;
       }
   }）
   .setNegativeButton（否，新DialogInterface.OnClickListener（）{
       公共无效的onClick（DialogInterface对话框，INT ID）{
            dialog.cancel（）;
       }
   }）;
AlertDialog警报= builder.create（）;
 

解决方案

是的，你可以。你基本上需要：

1. 创建与DialogBu​​ilder对话框
2. 显示（）对话框
3. 找到在对话框中显示的按钮和覆盖其onClickListener

因此​​，创建一个监听器类：

 类CustomListener实现View.OnClickListener {
    私人最终对话框对话框;
    公共CustomListener（对话对话框）{
        this.dialog =对话框;
    }
    @覆盖
    公共无效的onClick（视图v）{

        //做你想做这里

        //如果土特产品要关闭对话框，取消下面的行
        //dialog.dismiss（）;
    }
}
 

然后显示在对话框使用的时候：

  AlertDialog对话框= dialogBu​​ilder.create（）;
dialog.show（）;
按钮theButton = dialog.getButton（DialogInterface.BUTTON_POSITIVE）;
theButton.setOnClickListener（新CustomListener（对话））;
 

记住，你需要显示的对话框，否则按钮不会findeable。此外，一定要修改 DialogInterface.BUTTON_POSITIVE 以任何价值，你用来添加按钮。另外请注意，添加的按钮DialogBu​​ilder当你将需要提供onClickListeners - 你不能添加自定义监听器在那里，虽然 - 对话仍然会解散，如果你不重写后演出的听众（）被调用。

I would like to keep my dialog open when I press a button. At the moment it's closing! Please help!

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setMessage("Are you sure you want to exit?")

   .setCancelable(false)
   .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            MyActivity.this.finish();
       }
   })
   .setNegativeButton("No", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
       }
   });
AlertDialog alert = builder.create();

解决方案

Yes, you can. You basically need to:

1. Create the dialog with DialogBuilder
2. show() the dialog
3. Find the buttons in the dialog shown and override their onClickListener

So, create a listener class:

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

        // Do whatever you want here

        // If tou want to close the dialog, uncomment the line below
        //dialog.dismiss();
    }
}

Then when showing the dialog use:

AlertDialog dialog = dialogBuilder.create();
dialog.show();
Button theButton = dialog.getButton(DialogInterface.BUTTON_POSITIVE);
theButton.setOnClickListener(new CustomListener(dialog));

Remember, you need to show the dialog otherwise the button will not be findeable. Also, be sure to change DialogInterface.BUTTON_POSITIVE to whatever value you used to add the button. Also note that when adding the buttons in the DialogBuilder you will need to provide onClickListeners - you cannot add the custom listener in there, though - the dialog will still dismiss if you do not override the listeners after show() is called.
