I have this master view where I have a TableLayout to which I add new views programmatically. The master view is given below (masterLayout.xml)
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tableLayoutActivity"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
android:padding="5dp"
android:stretchColumns="*">
<TableRow
android:id="@+id/tableRow3"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#fff"
android:weightSum="2">
<ScrollView
android:id="@+id/queryScrollView"
android:layout_width="match_parent"
android:layout_span="2"
android:padding="5dp">
<TableLayout
android:id="@+id/queryTableLayoutActivity"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="5dp"
android:stretchColumns="*"></TableLayout>
</ScrollView>
</TableRow>
In the above view I add new views to queryTableLayoutActivity Layout. The layout to be added is given below (childLayout.xml)

I add the childLayout.xml to masterLayout.xml using the following code
TableLayout queryTableLayout = (TableLayout) findViewById(R.id.queryTableLayoutActivity);
LayoutInflater inflater = (LayoutInflater) getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
String courseIDValue = c.getString(courseIdIndex);
View newTagView = inflater.inflate(R.layout.activity_class_activities, null);
queryTableLayout.addView(newTagView, activeClassActivityIndex++);
I want to sort childLayout based on dueDateActivity field. How can I achieve this?
According to bedbad's 4 steps I followed first 2 and found solution
I used this answer to help my situation. This is my sort method (on button click)
public void sortByWeek(View v){
queryTableLayout = (TableLayout) findViewById(R.id.queryTableLayoutActivity);
int childCount = queryTableLayout.getChildCount();
Map<View,String> map = new HashMap<View,String>();
for(int i = 0; i<childCount;i++){
map.put(queryTableLayout.getChildAt(i),((TextView)queryTableLayout.getChildAt(i).findViewById(R.id.dueDateActivity)).getText().toString());
}
Map<View,String> sortedMap = sortByComparator(map,sort);
ArrayList<View> viewSet = new ArrayList<>(sortedMap.keySet());
queryTableLayout.removeAllViews();
for(int i = 0;i<childCount;i++){
queryTableLayout.addView(viewSet.get(i));
}
if(sort){
sort = false;
}
}
public Map<View,String> sortByComparator(Map<View,String> map,final boolean order){
List<Map.Entry<View,String>> list = new LinkedList<Map.Entry<View,String>>(map.entrySet());
Collections.sort(list, new Comparator<Map.Entry<View, String>>() {
@Override
public int compare(Map.Entry<View, String> lhs, Map.Entry<View, String> rhs) {
if(order){
return lhs.getValue().compareTo(rhs.getValue());
}else{
return rhs.getValue().compareTo(lhs.getValue());
}
}
});
Map<View,String> sortedMap = new LinkedHashMap<View,String>();
for(Map.Entry<View,String> entry: list){
sortedMap.put(entry.getKey(),entry.getValue());
}
return sortedMap;
}
