我正在尝试在ListView中的项目上设置固定进度。我只在ListView中看到一个不确定的旋转圆圈....我做错了什么? (我确定答案很简单......我只是没有看到它)
对于以下适配器布局xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<TextView
android:id="@+id/some_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<ProgressBar
android:id="@+id/some_progress"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
代码:
public class SomeListAdapter extends ArrayAdapter<MyItem> {
private static class ViewHolder {
TextView nameTextView;
ProgressBar valueProgressBar;
}
public BestChoiceListAdapter(Context context, List<MyItem> items) {
super(context, R.layout.list_item, items);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
View view = convertView;
if (view == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(R.layout.list_item, null);
holder = new ViewHolder();
holder.nameTextView = (TextView) view.findViewById(R.id.some_text);
holder.valueProgressBar = (ProgressBar) view.findViewById(R.id.some_progress);
view.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
MyItem optionItem = getItem(position);
holder.nameTextView.setText(optionItem.getOptionName());
int progress = (int) (optionItem.getOptionValue());
holder.valueProgressBar.setProgress(progress);
return view;
}
}

最简单的方法是将水平样式应用于它:
<ProgressBar
android:id="@+id/some_progress"
style="@android:style/Widget.ProgressBar.Horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
这将设置您需要手动添加的所有属性以应用确定的进度模式。
如果您感到好奇,那么这就是系统样式的样子,以防您想要单独应用这些属性:
<style name="Widget.ProgressBar.Horizontal">
<item name="android:indeterminateOnly">false</item>
<item name="android:progressDrawable">@android:drawable/progress_horizontal</item>
<item name="android:indeterminateDrawable">@android:drawable/progress_indeterminate_horizontal</item>
<item name="android:minHeight">20dip</item>
<item name="android:maxHeight">20dip</item>
</style>

将indeterminate mode更改为false!
<ProgressBar
android:id="@+id/some_progress"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:indeterminate="false"
/>
