在我的应用程序只需简单的滑动菜单,我可以设置阵列适配器
,这是正常的工作。但我想设置的图标的ListView
阵列的每一行。在这低于code我的列表视图和多数民众的图像阵列确定,但我不能设置图标。

解决方案
您需要自定义布局和自定义适配器
下面是code
自定义布局 - > item_layout
< ImageView的 机器人:ID =@ + ID /图标 机器人:layout_width =的22px 机器人:layout_height =的22px 机器人:layout_marginLeft =递四方 机器人:layout_marginRight =10px的 机器人:layout_marginTop =递四方 机器人:SRC =@绘制/ abc_list_ pressed_holo_light>< / ImageView的><的TextView 机器人:ID =@ + ID / text1中 的xmlns:机器人=http://schemas.android.com/apk/res/android 机器人:ID =@机器人:ID / text1中 机器人:layout_width =match_parent 机器人:layout_height =WRAP_CONTENT 机器人:textAppearance =机器人:ATTR / textAppearanceListItemSmall 机器人:重力=center_vertical 机器人:paddingStart =机器人:ATTR /列表preferredItemPaddingStart 机器人:paddingEnd =机器人:ATTR /列表preferredItemPaddingEnd 安卓了minHeight =机器人:ATTR /列表preferredItemHeightSmall />
现在定制适配器
类CustomAdapter延伸BaseAdapter{私人LayoutInflater吹气;私人字符串值[];整数[] imgid;私有类ViewHolder { ImageView的imgView; TextView中的TextView; }公共CustomAdapter(上下文的背景下,的String []值,整数[] imgid){ this.values =值; this.imgid = imgid; 充气= LayoutInflater.from(上下文);}@覆盖公众诠释的getCount(){ 返回values.length;}@覆盖公共对象的getItem(INT指数){ 返回值[指数]}@覆盖众长getItemId(INT为arg0){ 返回将arg0;}@覆盖公共查看getView(INT位置,查看convertView,父母的ViewGroup){ ViewHolder支架=无效; 如果(convertView == NULL){ 持有人=新ViewHolder(); convertView = inflater.inflate(R.layout.item_layout,NULL); holder.imgView =(ImageView的)convertView.findViewById(R.id.icon); holder.textView =(TextView中)convertView.findViewById(R.id.text1); convertView.setTag(保持器); } 支架=(ViewHolder)convertView.getTag(); holder.textView.setText(值[位置]); holder.imgView.setBackgroundResource(imgid [位置]); 返回convertView;}}
in simple Slide menu of my application i can set array to Adapter
and this is work correctly. but i want to set Icon for each row of ListView
array. in this below code my array of listview and images of thats is ok but i can not set icon.
public class NavigationDrawerFragment extends Fragment {
.
.
.
public NavigationDrawerFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
.
.
.
.
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// Indicate that this fragment would like to influence the set of actions in the action bar.
setHasOptionsMenu(true);
ImageView iv = (ImageView) getActivity().findViewById(R.id.icon);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mDrawerListView = (ListView) inflater.inflate(
R.layout.fragment_navigation_drawer, container, false);
mDrawerListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
});
String[] values = new String[]{
"Android",
"iPhone",
"Blackberry",
"WebOS",
"Ubuntu",
"Max OS X",
"Linux",
"OS/2"
};
Integer[] imgid = new Integer[]{
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher
};
iv.setImageResource(R.drawable.abc_ab_solid_dark_holo);
mDrawerListView.
setAdapter(new ArrayAdapter<String>(
getActionBar().getThemedContext(),
android.R.layout.simple_list_item_1,
android.R.id.text1,
values)
);
mDrawerListView.setItemChecked(mCurrentSelectedPosition, true);
return mDrawerListView;
}

</LinearLayout>
解决方案
You need a custom layout and a custom adapter
Below is the code
Custom layout-> item_layout
<ImageView
android:id="@+id/icon"
android:layout_width="22px"
android:layout_height="22px"
android:layout_marginLeft="4px"
android:layout_marginRight="10px"
android:layout_marginTop="4px"
android:src="@drawable/abc_list_pressed_holo_light">
</ImageView>
<TextView
android:id="@+id/text1"
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:paddingStart="?android:attr/listPreferredItemPaddingStart"
android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
/>
Now the custom adapter
class CustomAdapter extends BaseAdapter
{
private LayoutInflater inflater;
private String values[];
Integer[] imgid;
private class ViewHolder {
ImageView imgView;
TextView textView;
}
public CustomAdapter(Context context,String[]values,Integer[] imgid)
{
this.values=values;
this.imgid=imgid;
inflater = LayoutInflater.from(context);
}
@Override
public int getCount() {
return values.length;
}
@Override
public Object getItem(int index) {
return values[index];
}
@Override
public long getItemId(int arg0) {
return arg0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
ViewHolder holder = null;
if(convertView ==null){
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.item_layout, null);
holder.imgView = (ImageView)convertView.findViewById(R.id.icon);
holder.textView = (TextView)convertView.findViewById(R.id.text1);
convertView.setTag(holder);
}
holder = (ViewHolder) convertView.getTag();
holder.textView.setText(values[position]);
holder.imgView.setBackgroundResource(imgid[position]);
return convertView;
}
}
