解决方案

有关更改颜色/高/宽或ListView项中的任何外观和外观，你必须使用自定义适配器定义自定义列表视图。

首先，定义列表项排文件为您的列表视图，其中采取一个TextView与任何你想要的，然后该行文件传递给您的自定义适配器的颜色。

下面是我的例子： tinyurl.com/buq5wdx ，通过这个例子，使定制按您的要求

更新：

我跟Pragna的回答完全同意，但如果你仍然想拥有的ListView的东西，如2 textviews 1 ImageView的，1 ImageView的和1的TextView或任何控制，你必须通过定义自定义适配器以自定义列表视图。

android:layout_width="fill_parent"
android:layout_height="fill_parent"

xmlns:android="http://schemas.android.com/apk/res/android">

<LinearLayout android:layout_height="match_parent" android:id="@+id/linearLayout1" android:layout_width="wrap_content" android:orientation="vertical">
    <LinearLayout android:layout_height="wrap_content" android:id="@+id/linearLayout2" android:layout_width="match_parent">
    <TextView android:text="All Contacts" 
        android:id="@+id/textView1" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:background="#808080"
        android:textColor="#000000">
        </TextView>
    </LinearLayout>
 <LinearLayout android:layout_height="wrap_content" android:id="@+id/linearLayout2" android:layout_width="match_parent"> 
   <ListView android:id="@+id/ListView01"

android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
</LinearLayout>
</LinearLayout>

Java code:

private ListView lv1;
    private String lv_arr[]={"Android","iPhone","BlackBerry","AndroidPeople","Android","iPhone"};
    @Override
    public void onCreate(Bundle icicle)
    {
        super.onCreate(icicle);
        setContentView(R.layout.contact_activity);
        lv1=(ListView)findViewById(R.id.ListView01);    
        lv1.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , lv_arr));

        lv1.setOnItemClickListener(new OnItemClickListener() 
        {

            public void onItemClick(AdapterView<?> parent, View view,int position, long id) 
            {

                      String selecteditem = lv_arr[position];
                      Intent myIntent = new Intent(view.getContext(), ContactInfo.class);
                      myIntent.putExtra("item", selecteditem);
                      startActivity(myIntent);
            }
        });
    }       

解决方案

For changing the color/height/width or any look and appearance of listview item, you have to define your custom listview with custom adapter.

First, define listitem row file for your listview, in which take a Textview with the color whatever you want and then pass this row file to your custom adapter.

Here is my example: tinyurl.com/buq5wdx , go through this example and make customization as per your requirement.

Update:

I am totally agree with Pragna's answer, but if you still want to have listview with something like 2 textviews with 1 imageview, 1 imageview and 1 textview or any control, you have to customize the listview by defining Custom Adapter.
