View.onClickListner不能从其他类中调用 [英] View.onClickListner not called from other class
问题描述
随着裁判我的previous问题在<一个href=\"http://stackoverflow.com/questions/10991805/button-not-shown-in-alertdialog#comment14360203_10991805\">button在alertDialog
With ref to my previous question in button not shown in alertDialog
我创建延伸AlertDialog类。在课堂上,我设置的XML有按钮的内容,但我的按钮没有响应。我的自定义警报的Java文件是
I am creating a class which extends AlertDialog. In the class I am setting the content from xml which has buttons, but my button is not responding. my custom alert java file is
public class DateTimeDialog extends AlertDialog{
Date date;
String title;
View.OnClickListener listner;
protected DateTimeDialog(Context context, String title, Date date ) {
super(context, android.R.style.Theme_Holo_Light_Dialog);
// TODO Auto-generated constructor stub
this.title = title;
this.date = date;
}
public void initListener(View.OnClickListener listner){
this.listner = listner;
}
@Override
public void onCreate(Bundle savedInstanceState){
//super.onCreate(savedInstanceState);
setContentView(R.layout.date_time_picker);
setTitle(title);
Button dialogButtonOK = (Button) findViewById(R.id.btn_ok);
// if button is clicked, close the custom dialog
dialogButtonOK.setOnClickListener(listner);
Button dialogButtonCancel = (Button) findViewById(R.id.btn_cancel);
// if button is clicked, close the custom dialog
dialogButtonCancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View dialog) {
// TODO Auto-generated method stub
}
});
}
我的方法调用这个类是
My method calling this class is
final DateTimeDialog dateTimeDialog = new DateTimeDialog(context, "Title", date);
dateTimeDialog.show();
dateTimeDialog.initListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//done something
}
});
问题是点击,但取消被调用的时候我的OK按钮没有被调用。
我不知道我在哪里得到wrong.Please帮助!

推荐答案
试试这个:
public void initListener(View.OnClickListener listner){
this.listner = listner;
Button dialogButtonOK = (Button) findViewById(R.id.btn_ok);
dialogButtonOK.setOnClickListener(listner);
}
