在我的应用程序中,我想更改列表视图文本颜色。在这种情况下,我使用XML文件进行列表视图。可能吗?如果是,那么举个例子。

gender.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical"
 android:background="@drawable/topelg"
 >

      <ListView
        android:id="@+id/android:list"
        android:layout_marginTop="60dip"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:textColor="#000000"

        />

</LinearLayout>

Egender.java

package com.Elgifto;

import android.app.ListActivity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;
import android.widget.ListView;

public class Egender extends ListActivity{
    Button b1;
    ListView lv;

     /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gender);

       // b1=(Button) findViewById(R.id.butt1);
        b1=new Button(this);
        b1.setText("Done");

       //b1.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        lv=(ListView) findViewById(android.R.id.list);

        lv.addHeaderView(b1);  

        b1.setOnClickListener(new OnClickListener(){
              public void onClick(View v)
              {
                  // To send a result, simply call setResult() before your
                  // activity is finished.

                  finish();
              }
        });

        lv.setAdapter(new ArrayAdapter&lt;String&gt;(this,
                android.R.layout.simple_list_item_single_choice, GENDER));

       lv.setBackgroundColor(Color.BLACK);
        lv.setItemsCanFocus(false);
        lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
        lv.setTextFilterEnabled(true);

    }

    private static final String[] GENDER = new String[] {
       "Male","Female"
    };
}

如果您想更改所有ListView项的颜色,而不是将默认android.R.layout.simple_list_item_single_choice传递给ArrayAdapter,则应传递自定义列表项XML,它具有不同的TextColor属性。

例如,在文件夹布局下创建了custom_list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text1"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:checkMark="?android:attr/listChoiceIndicatorSingle"
android:paddingLeft="6dip"
android:paddingRight="6dip"
android:textColor="#FF0000"
/>

然后将其传递给适配器:

new ArrayAdapter<String>(this, R.layout.custom_list_item, stringList)

我有清单,所有物品都是红色的。
