String[] types = {"Item 1","Item 2","Item 3" }; 
b.setItems(types, new DialogInterface.OnClickListener() { 

    @Override

     dialogInterface.dismiss(); 

     //How to get the selected text

}); 

b.show(); 

Answer 1

获得所选项目的文字我找到了一种方法。但不知道这是否是最好的方法。

AlertDialog.Builder b = new AlertDialog.Builder(SettingsCustom.this); 
b.setTitle("Example"); 
final String[] types = {"Item 1","Item 2","Item 3" }; 
b.setItems(types, new DialogInterface.OnClickListener() { 

    @Override 
    public void onClick(DialogInterface dialogInterface, int which) { 
     dialogInterface.dismiss(); 

     //How to get the selected text 
     Log.v("-----> " , "selected text = " + types[which]); 
    } 
}); 

b.show();

您需要注册DialogInterface.OnClickListener并使用setPostivie，setsinglechoice，setmultichoice等方法。
