Android如何在每个listvIew列表项上添加图标并更改文本颜色，背景颜色

我有一个带有一些列表项的导航抽屉。如何在每个列表项上添加图标并更改文本颜色，背景颜色。

这是我的代码

Java的

mDrawerListView.setAdapter(new ArrayAdapter( getActionBar().getThemedContext(), android.R.layout.simple_list_item_activated_1, android.R.id.text1, new String[]{ getString(R.string.title_section1), getString(R.string.title_section2), getString(R.string.title_section3), })); 

XML

NavigationDrawerFragment.java 请在此处输入以下答案

为此，您需要创建自定义适配器。 您可以在下面的链接中找到自定义适配器的实现，

http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/

上面包含一个很好的自定义适配器教程，可以在每个列表行中添加图标，更改文本和背景颜色….

这里也是关于自定义适配器的好教程，

http://androidexample.com/How_To_Create_A_Custom_Listview_-_Android_Example/index.php?view=article_discription&aid=67&aaid=92

这是一个例子，

你的活动的xml应该像这个activity_main.xml，

您的Activity类：公共类MainActivity扩展Activity {

 private ListView listView1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); String[] textString = {"Item1", "Item2", "Item3", "Item4"}; int[] drawableIds = {R.drawable.img_id_row1, R.drawable.img_id_row2, R.drawable.img_id_row3, R.drawable.img_id_row4}; CustomAdapter adapter = new CustomAdapter(this, textString, drawableIds); listView1 = (ListView)findViewById(R.id.menuList); listView1.setAdapter(adapter); } 

为每行创建另一个布局，如下所示，并将其命名为row.xml，

现在，创建一个JAVA类并将其命名为CustomAdapter.java：

 public class CustomAdapter extends BaseAdapter { private Context mContext; private String[] Title; private int[] imge; public CustomAdapter(Context context, String[] text1,int[] imageIds) { mContext = context; Title = text1; imge = imageIds; } public int getCount() { // TODO Auto-generated method stub return Title.length; } public Object getItem(int arg0) { // TODO Auto-generated method stub return null; } public long getItemId(int position) { // TODO Auto-generated method stub return position; } public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = getLayoutInflater(); View row; row = inflater.inflate(R.layout.row, parent, false); TextView title; ImageView i1; i1 = (ImageView) row.findViewById(R.id.imgIcon); title = (TextView) row.findViewById(R.id.txtTitle); title.setText(Title[position]); i1.setImageResource(imge[position]); return (row); } }
