I wrote code in activity.java like this..

我想在IM1，IM2，IM3使用对话框，每必须得到另一个事件。
然后，我必须写3对话框？
以及如何我可以设置[// TODO自动...]在这里，我用的是如..
第一个对话框IM1，
第二个对话框IM2，
对于IM3 ..

推荐答案

您可以写的警告对话框中的私有变量，并重新使用它，但不能在同一时间

You can write a private variable for the alert dialog and reuse it, but not at the same time

private AlertDialog mDialog = new AlertDialog.Builder(this)
            .setTitle("Gmelon")
            .setMessage("setting?")
            .setPositiveButton("YES",
                    new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Log.i("MyTag" , "Click YES");
                }
            })

            .setNegativeButton("NO",
                    new android.content.DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Log.i("MyTag", "Click NO");
                }
            }).create();

现在可以显示以往任何时候都在你的code想去的地方对话框。

now you can show the dialog where ever you want in your code.
