Question

当然这应该有用吗？我只得到一个圆形不确定的微调器。我做错了什么！？

 // Assume oListElements is a list of strings
 ArrayAdapter<String> oArrayAdapter  = new ArrayAdapter<String> (this,android.R.layout.simple_list_item_1,oListElements);
 oListView.setAdapter(oArrayAdapter);

@Override
public void onItemClick(AdapterView<?> oArg1, View oView, int iInt1, long iInt2)
{
    /*
     * Also tried:
     * ProgressDialog oProgressDialog = new ProgressDialog(this,ProgressDialog.STYLE_HORIZONTAL);
     */
    ProgressDialog oProgressDialog = new ProgressDialog(this);
    oProgressDialog.setProgress(ProgressDialog.STYLE_HORIZONTAL);
    oProgressDialog.setMax(100);
    oProgressDialog.setMessage("PD Message");
    oProgressDialog.show();
}

如果您需要，我的XML很简单：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".TrainingMode" >

    <ListView
        android:id="@+id/scroll_view_listview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        >

    </ListView>

</RelativeLayout>

忽略这一点，我只需要绕过愚蠢的Stack Overflow代码/单词检查。 Blah blah blah blah blah blah。

使用ProgressDialog.setIndeterminate使进度条不确定并使用ProgressDialog.setProgressStyle（而不是ProgressDialog.setProgress）强制进行水平布局：

oProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
oProgressDialog.setIndeterminate(false);

ListView onItemClick水平进度条
