我想在单个屏幕上设置3个expandablelistview我想添加多个expandablelistview
XmlLayout
//this is my scorllview
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
tools:context=".fragments.FragmentTestWellnessscoreBoard">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:id="@+id/llHealth"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="@+id/tvHealthTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:layout_margin="@dimen/margin_10"
android:text="Health"/>
<ExpandableListView
android:id="@+id/elHealth"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<LinearLayout

我想在用户点击时设置逐个适配器我不知道如何设置多个expandableList？
Java文件
private TestWellnessscoreBoardExpandableListAdapter mHealthaAdapter; private TestWellnessscoreBoardExpandableListAdapter mChallengeAdapter; private TestWellnessscoreBoardExpandableListAdapter mRiskAdapter; private ExpandableListView elHealth; private ExpandableListView elChallenge; private ExpandableListView elRisk; // this is my click listener to set adapter private View.OnClickListener mOnClickListener = new View.OnClickListener() { @Override public void onClick(View v) { switch (v.getId()) { case R.id.tvHealthTitle: mHealthaAdapter = new TestWellnessscoreBoardExpandableListAdapter(getActivity(),mWellnessResult.getWellnessArrayList()); elHealth.setAdapter(mHealthaAdapter); break; case R.id.tvChallengeTitle: mChallengeAdapter = new TestWellnessscoreBoardExpandableListAdapter(getActivity(),mWellnessResult.getWellnessArrayList()); elChallenge.setAdapter(mChallengeAdapter); break; case R.id.tvRiskTitle: mRiskAdapter = new TestWellnessscoreBoardExpandableListAdapter(getActivity(),mWellnessResult.getWellnessArrayList()); elRisk.setAdapter(mRiskAdapter); break; } } };
解决方法
试试这个：
xml代码：
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/activity_expandable_scroll_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin">
<ExpandableListView
android:id="@+id/activity_expandable_list_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/white"/>
</LinearLayout>
</ScrollView>
java类
mListView = (ExpandableListView) findViewById(R.id.activity_expandable_list_view);
MyExpandableListAdapter adapter = new MyExpandableListAdapter(this,mGroups);
mListView.setAdapter(adapter);
mListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
@Override
public boolean onGroupClick(ExpandableListView parent,View v,int groupPosition,long id) {
setListViewHeight(parent,groupPosition);
return false;
}
});
需要这个功能：
private void setListViewHeight(ExpandableListView listView,int group) {
ExpandableListAdapter listAdapter = (ExpandableListAdapter) listView.getExpandableListAdapter();
int totalHeight = 0;
int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(),View.MeasureSpec.EXACTLY);
for (int i = 0; i < listAdapter.getGroupCount(); i++) {
View groupItem = listAdapter.getGroupView(i,false,null,listView);
groupItem.measure(desiredWidth,View.MeasureSpec.UNSPECIFIED);
totalHeight += groupItem.getMeasuredHeight();
if (((listView.isGroupExpanded(i)) && (i != group))
|| ((!listView.isGroupExpanded(i)) && (i == group))) {
for (int j = 0; j < listAdapter.getChildrenCount(i); j++) {
View listItem = listAdapter.getChildView(i,j,listView);
listItem.measure(desiredWidth,View.MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
}
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
int height = totalHeight
+ (listView.getDividerHeight() * (listAdapter.getGroupCount() - 1));
if (height < 10)
height = 200;
params.height = height;
listView.setLayoutParams(params);
listView.requestLayout();
}
