Question

我想更改listview文本颜色但不改变。此外，我使用了不同的列表样式，但列表中的文本颜色没有变化。帮我解决这个问题这是代码

 public class Line extends Activity
 {

List<Map<String, String>> data;

Map<String, String> Line1;
Map<String, String> Line2;

ListView Lines = null;

public void onCreate(final Bundle savedInstanceState) 
{

    Lines = new ListView(Line.this);
    Lines = (ListView) findViewById(R.id.list);

    data = new ArrayList<Map<String, String>>();

    Line1 = new HashMap<String, String>();

    Line1.put("title", "Row | 1" );
    Line1.put("status", "");
    data.add(Line1);

   Line2 = new HashMap<String, String>();

    Line2.put("title", "Row | 2" );
    Line2.put("status", "");
    data.add(Line2);


    SimpleAdapter adapter = new SimpleAdapter(this, data, android.R.layout.simple_list_item_2, new String[] {"title", "status"}, new int[] {android.R.id.text1, android.R.id.text2});

    Lines.setAdapter(adapter);


void SetStatus(int nLineNo, String sStatusMsg)
{
    if(nLineNo == 0)
    {
        Line1 = new HashMap<String, String>();
        Line1.put("title", "Line | 1" );
        Line1.put("status", sStatusMsg);
        data.set(0, Line1);

        SimpleAdapter adapter = new SimpleAdapter(this, data, android.R.layout.simple_list_item_2, new String[] {"title", "status"}, new int[] {android.R.id.text1, android.R.id.text2});

        Lines.setAdapter(adapter);
    }

    if(nLineNo == 1)
    {
        Line2 = new HashMap<String, String>();
        Line2.put("title", "Line | 2" );
        Line2.put("status", sStatusMsg);
        data.set(1, Line2);
        SimpleAdapter adapter = new SimpleAdapter(this, data, android.R.layout.simple_list_item_2, new String[] {"title", "status"}, new int[] {android.R.id.text1, android.R.id.text2});

        Lines.setAdapter(adapter);
    }

    }

列表视图的xml

    <TableRow
            android:id="@+id/tableRow1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" 
           >


        <ListView
            android:id="@+id/list"
            android:layout_width="wrap_content"
            android:layout_height="338dp"
            android:padding="10dip" 
            android:listSelector="#372f89"
            style="@drawable/liststyle"
             android:textColor="@color/tabDark"
              android:background="#fcfbdf" 
            android:scrollbars="none" 
            android:cacheColorHint="#ffffff">

            <!-- Preview: listitem=@android:layout/simple_list_item_2 -->

        </ListView>

</TableRow>

list style xml

   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearLayout1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >


 <TextView
        android:id="@android:id/text1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:minHeight="?android:attr/listPreferredItemHeight"
        android:paddingLeft="6dip"
        android:textColor="@color/circlebtn"
        android:paddingRight="10dip"
        android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>

目前，您正在传递使用默认android.R.layout.simple_list_item_2的ListView行的simple_list_item_2。

将list style xml（假设由您创建）传递给SimpleAdapter：

   SimpleAdapter adapter = new SimpleAdapter(this, data,  
        R.layout.<list style xml>, new String[] {"title", "status"}, 
        new int[] {android.R.id.text1, android.R.id.text2});
