我正在使用ExpandableListActivity
,在底部我有一个ProgressBar来确定检查了多少行。
活动的XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="@+id/activity_main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="100" >
<include
android:id="@+id/activity_checklist_titlebar"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="10"
layout="@layout/titlebar" />
<ExpandableListView
android:id="@+id/android:list"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="90" >
</ExpandableListView>
</LinearLayout>
<ProgressBar
android:id="@+id/activity_checklist_progress"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="@dimen/height_activity_checklist_progress"
android:layout_alignParentBottom="true" />
<TextView
android:id="@+id/activity_checklist_progress_text"
style="@style/Text.Strong.Medium"
android:layout_width="wrap_content"
android:layout_height="@dimen/height_activity_checklist_progress"
android:gravity="center"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="0/50" />
</RelativeLayout>
我在这里更新进度:
@Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent)
{
// ...
TextView overall_progress_text =
(TextView) main_layout.findViewById(R.id.activity_checklist_progress_text);
int overall_progress = checklist.getProgress();
overall_progress_text.setText(overall_progress + "/" + checklist.size());
ProgressBar overall_progress_bar =
(ProgressBar) main_layout.findViewById(R.id.activity_checklist_progress);
overall_progress_bar.setProgress(overall_progress);
overall_progress_bar.setMax(checklist.size());
return convertView;
}
正如您所看到的,我有一个显示进度的TextView,显然值很好。当我开始更改列表中的复选框状态时,一切都正常,唯一的问题是在活动开始时。
progressBar显示了这一点(我认为最大值是'100'而不是'9'):
答案 0 :(得分:2)
我只是解决了在进度之前设置最大值的问题。即使您在进度后设置了最大值,Android的ProgressBar似乎也不起作用......
改变了这个:
overall_progress_bar.setProgress(overall_progress);
overall_progress_bar.setMax(checklist.size());
对此:
overall_progress_bar.setMax(checklist.size());
overall_progress_bar.setProgress(overall_progress);
答案 1 :(得分:0)
您可以使用Async Task查看进度,在onProgressUpdate中可以设置进度对话框或进度条。
