进度条不动
我的列表视图中的每个项目都有进度条。当我点击列表中的某个项目时，另一个线程会使进度条移动。由于某种原因，输出显示进度条正在增加，但事实并非如此。下面是一些代码。
mHandler.post(new Runnable() {
public void run() {
ViewHolder vh = (ViewHolder) adapter.getView(pro, null, null).getTag();
Log.d("Progress",String.valueOf(vh.progress.getProgress()));
vh.progress.setProgress((int) prog[pro]);
}
});
I have progress bar in every item inside my listview. When I tap an item on the list, another thread makes the progress bar move. For some reason the output says the progress bar is increasing but it's not. Below is some of the code.
mHandler.post(new Runnable() {
public void run() {
ViewHolder vh = (ViewHolder) adapter.getView(pro, null, null).getTag();
Log.d("Progress",String.valueOf(vh.progress.getProgress()));
vh.progress.setProgress((int) prog[pro]);
}
});

Adapter上的getView()可能会创建一个全新的行，因为这就是您调用getView()时应该执行的操作第二个参数为null。您需要有一个更好的方案来检索要更新的
ProgressBar，同时考虑到ProgressBar可能已被回收以显示其他行的进度。getView()on yourAdapteris probably creating a brand new row, since that's what it is supposed to do when you callgetView()with anullsecond parameter.You need to have a better scheme for retrieving the
ProgressBarthat you wish to update, taking into account that theProgressBarmay have been recycled to be displaying some other row's progress.
