You need to create a CustomListAdapter. 

<pre><code>public class CustomListAdapter extends ArrayAdapter &lt;String&gt; {

 private Context mContext;
 private int id;
 private List &lt;String&gt;items ;

 public CustomListAdapter(Context context, int textViewResourceId , List&lt;String&gt; list ) 
 {
 super(context, textViewResourceId, list); 
 mContext = context;
 id = textViewResourceId;
 items = list ;
 }

 @Override
 public View getView(int position, View v, ViewGroup parent)
 {
 View mView = v ;
 if(mView == null){
 LayoutInflater vi = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
 mView = vi.inflate(id, null);
 }

 TextView text = (TextView) mView.findViewById(R.id.textView);

 if(items.get(position) != null )
 {
 text.setTextColor(Color.WHITE);
 text.setText(items.get(position));
 text.setBackgroundColor(Color.RED); 
 int color = Color.argb( 200, 255, 64, 64 );
 text.setBackgroundColor( color );

 }

 return mView;
 }

}
</code></pre>

The list item looks like this (custom_list.xml): 

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"&gt;
&lt;TextView 
 android:layout_width="fill_parent" 
 android:layout_height="wrap_content" 
 android:id="@+id/textView"
 android:textSize="20px" android:paddingTop="10dip" android:paddingBottom="10dip"/&gt;
&lt;/LinearLayout&gt;
</code></pre>

Use the TextView api's to decorate your text to your liking

and you will be using it like this 

<pre><code>listAdapter = new CustomListAdapter(YourActivity.this , R.layout.custom_list , mList);
mListView.setAdapter(listAdapter);
</code></pre>

use them in Java code like this:

<pre><code> color = getResources().getColor(R.color.mycolor);
</code></pre>

The <code>getResources()</code> method returns the ResourceManager class for the current activity, and <code>getColor()</code> asks the manager to look up a color given a resource ID

blocks|key|571126|text|创建一个CustomAdapter，在其中您有getView()，所以如果您想要更改列表视图的背景颜色，请使用以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|571127|v.setBackgroundColor(Color.CYAN);|code-block|syntax|javascript|571128|如果您想要更改textColor，请执行以下操作：|571129|tv.setTextColor(Color.RED);|571130|而对于textSize：|571131|tv.setTextSize(20);|571132|其中'v‘是列表视图，'tv’是文本视图|571133|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|Y|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

Create a CustomAdapter and in that you have the getView() so there if you want to change the listview background color use this : 

<pre><code>v.setBackgroundColor(Color.CYAN);
</code></pre>

If you want to change the textColor then do this :

<pre><code>tv.setTextColor(Color.RED);
</code></pre>

and for the textSize : 

<pre><code>tv.setTextSize(20);
</code></pre>

where 'v' is the listview and 'tv' is the textview

If u want to set background of the list then place the image before the &lt; Textview>

<pre><code>&lt; ImageView
android:background="@drawable/image_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/&gt;
</code></pre>

and if u want to change color then put color code on above textbox like this

<pre><code> android:textColor="#ffffff"

blocks|key|571281|text|如果您只需要更改视图的一些参数和ArrayAdapter的默认行为，这对您来说是可以的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|571282|+import+android.content.Context;

If you just need to change some parameters of the View and the default behavior of ArrayAdapter its OK for you:

<pre><code> import android.content.Context;
 import android.view.View;
 import android.view.ViewGroup;
 import android.widget.ArrayAdapter;

 public class CustomArrayAdapter&lt;T&gt; extends ArrayAdapter&lt;T&gt; {

 public CustomArrayAdapter(Context context, int textViewResourceId) {
 super(context, textViewResourceId);
 }

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {
 View view = super.getView(position, convertView, parent);

 // Here all your customization on the View
 view.setBackgroundColor(.......);
 ...

 return view;
 }


 }
</code></pre>

blocks|key|571330|text|更好的是，您不需要为列表单元格视图创建单独的android+xml布局。如果列表只包含textview，你可以只使用"android.R.layout.simple_list_item_1“。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|571331|private+class+ExampleAdapter+extends+ArrayAdapter<String>{

Even better, you do not need to create separate android xml layout for list cell view. You can just use "android.R.layout.simple_list_item_1" if the list only contains textview.

<pre><code>private class ExampleAdapter extends ArrayAdapter&lt;String&gt;{

 public ExampleAdapter(Context context, int textViewResourceId, String[] objects) {
 super(context, textViewResourceId, objects);
 }

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {


 View view = super.getView(position, convertView, parent);

 TextView tv = (TextView) view.findViewById(android.R.id.text1);
 tv.setTextColor(0);

 return view;
 }
</code></pre>

I am trying to change my font(color and size) and the back ground on my ListView. I want to change it with code lines not on xml.
my list view looks like:
 the xml:

<pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="18sp" android:text="@string/hello"&gt;
&lt;/TextView&gt;
</code></pre>

and my code is

<pre><code>public class NewsActivity extends ListActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);

 // ArrayAdapter listItemAdapter = new ArrayAdapter( this,android.R.layout.simple_list_item_1, v_itemList );

 setListAdapter(new ArrayAdapter&lt;String&gt;(this, R.layout.list_item,ynetList));

 View v=getListView() ;

 ListView lv = getListView();
</code></pre>

what next? please give me an example base on my code
