私はListViewを持っており、その背景色を変更したいと思います。それはこのようになるはずです。 1.Item =グレー。 2.アイテム;白; 3.アイテム=グレー; 4. Item = whiteなど.2つの背景色が必要です。私はほぼ2時間それを達成しようとしています。私は混乱しています。私は解決策を思いつきません。あなたの誰かが私を助けてくれることを願っていますAndroid - 2色のリストビュー
私はそれを試してみました：だからここ
for(int counter = 0; counter < itemList.size(); counter++){
if(adapter.getItem(position) %2 == 1){
Layout.setBackgroundColor(Color.GREY)
};
else{
Layout.setBackgroundColor(Color.WHITE);
}
私の穴コードです。私はあなたの誰かが私に言うことを願って：
MainActivity
public class MainActivity extends Activity implements OnItemClickListener {
ListView lview3;
ListViewCustomAdapter adapter;
private ArrayList<Object> itemList;
private ItemBean bean;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
prepareArrayLits();
lview3 = (ListView) findViewById(R.id.listView1);
adapter = new ListViewCustomAdapter(this, itemList);
lview3.setAdapter(adapter);
lview3.setOnItemClickListener(this);
}
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id) {
// TODO Auto-generated method stub
RelativeLayout Layout = (RelativeLayout) findViewById(R.id.relativeLayout1);
ItemBean bean = (ItemBean) adapter.getItem(position);
for(int counter = 0; counter < itemList.size(); counter++){
adapter.getItem(position);
Layout.setBackgroundColor(Color.CYAN);}
Toast.makeText(this, "Title => "+bean.getTitle()+" \n Description => "+bean.getDescription(), Toast.LENGTH_SHORT).show();
}
/* Method used to prepare the ArrayList,
* Same way, you can also do looping and adding object into the ArrayList.
*/
public void prepareArrayLits()
{
itemList = new ArrayList<Object>();
AddObjectToList(R.drawable.ic_add, "add", "Add desc", "2");
AddObjectToList(R.drawable.ic_delete, "Delete", "Delete desc", "2");
AddObjectToList(R.drawable.ic_down, "Down", "Down desc", "2");
AddObjectToList(R.drawable.ic_info, "Information", "Information desc", "2");
AddObjectToList(R.drawable.ic_help, "Help", "Help desc", "2");

AddObjectToList(R.drawable.ic_search, "Search", "Search desc", "2");
AddObjectToList(R.drawable.ic_settings, "Settings", "Settings desc", "2");
}
// Add one item into the Array List
public void AddObjectToList(int image, String title, String desc, String duration)
{
bean = new ItemBean();
bean.setduration(duration);
bean.setDescription(desc);
bean.setImage(image);
bean.setTitle(title);
itemList.add(bean);
}
}
ItemBean
public class ItemBean
{
String title;
String description;
int image;
String duration;
public String getTitle() {
return title;
}
public String getDuration() {
return duration;
}
public void setTitle(String title) {
this.title = title;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public int getImage() {
return image;
}
public void setImage(int image) {
this.image = image;
}
public void setduration(String duration) {
this.duration = duration;
}
}
をListViewCustomAdapter
public class ListViewCustomAdapter extends BaseAdapter{
ArrayList<Object> itemList;
public Activity context;
public LayoutInflater inflater;
public ListViewCustomAdapter(Activity context,ArrayList<Object> itemList) {
super();
this.context = context;
this.itemList = itemList;
this.inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
// TODO Auto-generated method stub
return itemList.size();
}
public Object getItem(int position) {
// TODO Auto-generated method stub
return itemList.get(position);
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
public static class ViewHolder
{
ImageView imgViewLogo;
TextView txtViewTitle;
TextView txtViewDescription;
TextView duration;
}
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder holder;
if(convertView==null)
{
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.items, null);
holder.imgViewLogo = (ImageView) convertView.findViewById(R.id.imgViewLogo);
holder.txtViewTitle = (TextView) convertView.findViewById(R.id.txtViewTitle);
holder.txtViewDescription = (TextView) convertView.findViewById(R.id.txtViewDescription);
holder.duration = (TextView) convertView.findViewById(R.id.duration);
convertView.setTag(holder);
}
else
holder=(ViewHolder)convertView.getTag();
ItemBean bean = (ItemBean) itemList.get(position);
holder.imgViewLogo.setImageResource(bean.getImage());
holder.txtViewTitle.setText(bean.getTitle());
holder.txtViewDescription.setText(bean.getDescription());
holder.duration.setText(bean.getDuration());
return convertView;
}
}

すべてのヒントは、 おかげで参考になります。
私は1週間離れていたので、テストできませんでした。今私はそれを設定する方法を混乱させる。手伝って頂けますか？ oncreateでgetView（）を呼び出す必要がありますか？パラメータはどのように挿入すればよいですか？ ありがとう – Ahmad
