我一直在寻找其他人在这个问题上的答案，但到目前为止似乎没有任何工作。onChildClick Event for ExpandableListAdapter无法正常工作
目前我有一个ExpandableListAdapter，它是根据SDK附带的一个示例构建的。至于显示数据我得到它的工作很好，但我不能让onChildClick事件工作。我试着将XML元素上的focusable属性设置为false，但我仍然没有任何运气。
目前，这是我的代码：
MainActivity.java
package com.example.expandablelisttest;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.ExpandableListView;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ExpandableListView expandableListView = (ExpandableListView) findViewById(R.id.expandableListView1);
ExpandableListAdapter expandableAdapter = new ExpandableListAdapter();
expandableListView.setAdapter(expandableAdapter);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
ExpandableListAdapter.java
package com.example.expandablelisttest;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseExpandableListAdapter;
import android.widget.ExpandableListView;
import android.widget.TextView;
import android.widget.Toast;
public class ExpandableListAdapter extends BaseExpandableListAdapter
implements ExpandableListView.OnChildClickListener
{
private String[] groups = { "People Names", "Dog Names", "Cat Names", "Fish Names" };
private String[][] children = {
{ "Arnold", "Barry", "Chuck", "David" },
{ "Ace", "Bandit", "Cha-Cha", "Deuce" },
{ "Fluffy", "Snuggles" },
{ "Goldy", "Bubbles" }
};
public Object getChild(int groupPosition, int childPosition) {
return children[groupPosition][childPosition];
}
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
@Override
public View getChildView(int groupPosition, int childPosition,
boolean isLastChild, View convertView, ViewGroup parent)
{
if (convertView ==null)
{
LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
convertView = layoutInflater.inflate(R.layout.child_view, null);
}
TextView childTxt = (TextView) convertView.findViewById(R.id.childTxt);
childTxt.setText(getChild(groupPosition, childPosition).toString());
return convertView;
}
@Override
public int getChildrenCount(int groupPosition) {
return children[groupPosition].length;
}
@Override
public Object getGroup(int groupPosition) {
return groups[groupPosition];
}
@Override
public int getGroupCount() {
return groups.length;
}
@Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
@Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent)
{
if (convertView ==null)
{
LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
convertView = layoutInflater.inflate(R.layout.group_view, null);
}
TextView groupTxt = (TextView) convertView.findViewById(R.id.groupTxt);
groupTxt.setText(getGroup(groupPosition).toString());
return convertView;
}
@Override
public boolean hasStableIds() {
// TODO Auto-generated method stub
return true;
}
@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
// TODO Auto-generated method stub
return true;
}
@Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id)
{
Log.d("Result:", "Click event triggered");
return true;
}
}

如果任何人都可以看到，为什么我的点击事件不点火，可以帮助我。我将不胜感激。提前致谢。
完美！它现在有效。非常感谢。 –
