android中如何实现在自定义的listview中点击一个按钮一个对应的进度条加载？求高手解答

Answer 1

private class Adatpter extends BaseAdapter{
@Override
public int getCount() {
return 5;
}

@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}

@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = getLayoutInflater().inflate(R.layout.test_list_try_item, null);
Button btn = (Button) view.findViewById(R.id.test_list_try_item_button);
btn.setOnClickListener(new OnBtnClickListener((ProgressBar) view.findViewById(R.id.test_list_try_item_progressbar)));
return view;
}
}

private class OnBtnClickListener implements OnClickListener{
private int progress = 0;
private ProgressBar bar = null;

public OnBtnClickListener(ProgressBar bar){
this.bar = bar;
}

@Override
public void onClick(View v) {
if(null != bar)
bar.setProgress(progress);
progress = (progress + 10)%100;
}

}
不知道你要的是不是这样的效果。随便写的，能用，希望能帮到你

Answer 2

在listview监听里有个参数是view类型的，你直接那个参数.findviewbyid(R.id.xxx)就获取了控件的实例
再用线程改进度条的值就行了

追问

不行，得实现button的按钮监听，而这个监听是内部类，不能绑定进度条的(ProgressBar)convertView.findViewById(R.id.XXX)
