こんにちはこのような画面を準備する必要があります
これが拡張可能なリストビューの私のコードです
アダプタークラス：NewAdapter.java
public class NewAdapter extends BaseExpandableListAdapter {
public ArrayList<ParentBean> groupItem;
ArrayList<String> tempChild;
public ArrayList<Object> Childtem = new ArrayList<Object>();
public LayoutInflater minflater;
public Activity activity;
public NewAdapter(ArrayList<ParentBean> grList, ArrayList<Object> childItem) {
groupItem = grList;
this.Childtem = childItem;
}
public void setInflater(LayoutInflater mInflater, Activity act) {
this.minflater = mInflater;
activity = act;
}
@Override
public Object getChild(int groupPosition, int childPosition) {
return null;
}
@Override
public long getChildId(int groupPosition, int childPosition) {
return 0;
}
@Override
public View getChildView(int groupPosition, final int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
tempChild = (ArrayList<String>) Childtem.get(groupPosition);
TextView text = null;
if (convertView == null) {
convertView = minflater.inflate(R.layout.childrow, null);
}
text = (TextView) convertView.findViewById(R.id.textView1);
text.setText(tempChild.get(0));
text = (TextView) convertView.findViewById(R.id.textView2);
text.setText(tempChild.get(1));
text = (TextView) convertView.findViewById(R.id.textView3);
text.setText(tempChild.get(2));
convertView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(activity, tempChild.get(childPosition),
Toast.LENGTH_SHORT).show();
}
});
return convertView;
}
@Override
public int getChildrenCount(int groupPosition) {
return 1;
}
@Override
public Object getGroup(int groupPosition) {
return null;
}
@Override
public int getGroupCount() {
return groupItem.size();
}
@Override
public void onGroupCollapsed(int groupPosition) {
super.onGroupCollapsed(groupPosition);
}
@Override
public void onGroupExpanded(int groupPosition) {
super.onGroupExpanded(groupPosition);
}
@Override
public long getGroupId(int groupPosition) {
return 0;
}
@Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
ViewHolder holder=null;
if (convertView == null) {
convertView = minflater.inflate(R.layout.grouprow, null);
holder = new ViewHolder();
holder.name=(TextView)convertView.findViewById(R.id.playername);
holder.team = (TextView) convertView.findViewById(R.id.vs);
holder.salary = (TextView) convertView.findViewById(R.id.salary);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
ParentBean playerdetails = groupItem.get(groupPosition);
holder.name.setText(playerdetails.getPlayername());
holder.team.setText(playerdetails.getPlayerteam());
holder.salary.setText(playerdetails.getPlayersalary());
return convertView;
}
@Override
public boolean hasStableIds() {
return false;
}
@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return false;
}
private class ViewHolder {
TextView team;
TextView name;
TextView salary;
}
class ParentBean{
String playername,playerteam,playersalary;
public ParentBean(String playername,String playerteam,String playersalary) {
this.playername=playername;
this.playersalary=playersalary;
this.playerteam=playerteam;
}
/**
* @return the playername
*/
public String getPlayername() {
return playername;
}
/**
* @param playername the playername to set
*/
public void setPlayername(String playername) {
this.playername = playername;
}
/**
* @return the playerteam
*/
public String getPlayerteam() {
return playerteam;
}
/**
* @param playerteam the playerteam to set
*/
public void setPlayerteam(String playerteam) {
this.playerteam = playerteam;
}
/**
* @return the playersalary
*/
public String getPlayersalary() {
return playersalary;
}
/**
* @param playersalary the playersalary to set
*/
public void setPlayersalary(String playersalary) {
this.playersalary = playersalary;
}
}
}
これが私のアクティビティです：MainActivity.java
public class MainActivity extends ExpandableListActivity implements
OnChildClickListener {
Context context;
ArrayList<ParentBean> groupItem = new ArrayList<ParentBean>();
ArrayList<Object> childItem = new ArrayList<Object>();
NewAdapter mNewAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ExpandableListView expandbleLis = getExpandableListView();
expandbleLis.setDividerHeight(2);
expandbleLis.setGroupIndicator(null);
expandbleLis.setClickable(true);
expandbleLis.setFocusable(true);
context=this;
getData();
mNewAdapter = new NewAdapter(groupItem, childItem);
mNewAdapter.setInflater((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE),this);
getExpandableListView().setAdapter(mNewAdapter);
expandbleLis.setOnChildClickListener(this);
}
public void getData() {
JsonDataCallback callback=new JsonDataCallback(MainActivity.this) {
@Override
public void receiveData(Object object) {
String jsonData=(String)object;
setData(jsonData);
}
};
callback.execute("http://111.93.7.119:8080/FirstPickService/Players?sportid=fc2e88e6-ac87-4d27-b6b3-863baa9f06ec",null,null);
}
protected void setData(String jsonData) {
try {
JSONObject players=new JSONObject(jsonData);
final JSONArray playersArray=players.getJSONArray("players");
for(int i=0;i<playersArray.length();i++)
{
JSONObject jsonObj=playersArray.getJSONObject(i);
String teamplayer=jsonObj.getString("playerfullname");
String psalary=jsonObj.getString("playerprice");
String strTeamVS=jsonObj.getString("teamid")+"@"+jsonObj.getString("awayteam");
groupItem.add(mNewAdapter.new ParentBean(teamplayer, psalary, strTeamVS));
String strsalary = jsonObj.getString("playerpricelong");
ArrayList<String> child = new ArrayList<String>();
child.add(psalary);
child.add(strTeamVS);
child.add(strsalary);
childItem.add(child);
}
mNewAdapter.notifyDataSetChanged();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
Toast.makeText(MainActivity.this, "Clicked On Child",
Toast.LENGTH_SHORT).show();
return true;
}
}
よくわかりませんが、展開可能なリストがフォーカスを失い、リストアイテムをクリックしたときに子行が表示されないため、選択にボタンを使用しました...
