EDIT2 : I have now a proper design for my layout and I can scroll , but I have a new problem with my Custom Adapter. When I scroll, my editText are loosing their content and are replaced by other content from other element. But When I use a SimpleCursorAdapter, then I don't have any problem (but I can't use my button).
Here is my Custom Adapter :
private class MySimpleCursorAdapter extends SimpleCursorAdapter
{
ViewHolder vh;
public MySimpleCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to, int flags) {
super(context, layout, c, from, to, flags);
cursor = c;
}
public View newView(Context _context, Cursor _cursor, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) _context.getSystemService(_context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.card_stock, parent, false);
vh = new ViewHolder();
vh.idList = (TextView) view.findViewById(R.id.idList);
vh.themeList = (TextView) view.findViewById(R.id.themeList);
vh.questionList = (TextView) view.findViewById(R.id.questionList);
vh.reponseList = (TextView) view.findViewById(R.id.reponseList);
vh.difficulteList = (TextView) view.findViewById(R.id.difficultList);
vh.Supprimer = (Button) view.findViewById(R.id.buttonDelete);
vh.Modifier = (Button) view.findViewById(R.id.buttonModifier);
view.setTag(vh);
return view;
}
public void bindView(View view, Context Context, Cursor cursor) {
vh.idList.setText(cursor.getString(cursor.getColumnIndex(stock._ID)));
vh.themeList.setText(cursor.getString(cursor.getColumnIndex(stock.THEME)));
vh.questionList.setText(cursor.getString(cursor.getColumnIndex(stock.QUESTION)));
vh.reponseList.setText(cursor.getString(cursor.getColumnIndex(stock.REPONSE)));
vh.difficulteList.setText(cursor.getString(cursor.getColumnIndex(stock.DIFFICULTE)));
vh.Supprimer.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
View parentView = (View)v.getParent();
TextView idList = (TextView) parentView.findViewById(R.id.idList);
int id = Integer.parseInt(idList.getText().toString());
deleteOneCard(id);
Toast.makeText(container.getContext(), "Suppression de "+id, Toast.LENGTH_SHORT).show();
}
});
vh.Modifier.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
View parentView = (View)v.getParent();
TextView idList = (TextView) parentView.findViewById(R.id.idList);
TextView themeList = (TextView) parentView.findViewById(R.id.themeList);
themeList.setFocusable(true);
themeList.requestFocus();
/*TextView questionList = (TextView) parentView.findViewById(R.id.questionList);
TextView reponseList = (TextView) parentView.findViewById(R.id.reponseList);
TextView difficulteList = (TextView) parentView.findViewById(R.id.difficultList);*/
int id = Integer.parseInt(idList.getText().toString());
Toast.makeText(container.getContext(), "bouton Modifier pour "+id, Toast.LENGTH_SHORT).show();
}
});
}
}
public class ViewHolder
{
Button Supprimer, Modifier;
TextView idList, themeList, questionList, reponseList, difficulteList;
}
Thank you guys.
Set the ListView
height to match_parent
. So, it will occupy the complete area of the parent View
.
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/listView"
android:scrollingCache="true"/>
Try adding everything scrollable inside a single RelativeLayout and this one inside a ScrollView.
<ScrollView>
<RelativeLayout>
// other elements
or
<ScrollView>
<ListView>
The RelativeLayout in the first example is necessary because the ScrollView element accepts only one child.
<RelativeLayout 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:background="@android:color/darker_gray">
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollingCache="true"/>
</RelativeLayout>
or
Use LinearLayout and Change the ListView
height to 0dp
and add weight=1
<LinearLayout
........
android:orientation="vertical">
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:scrollingCache="true"/>
</LinearLayout>
I have resolver my problem ! In my inner class that extends SimpleCursorAdapter, in my bindView function, I had to initialize again my editText !! Like this :
public void bindView(View view, Context Context, Cursor cursor) {
//EDIT
vh.idList = (TextView) view.findViewById(R.id.idList);
vh.themeList = (TextView) view.findViewById(R.id.themeList);
vh.questionList = (TextView) view.findViewById(R.id.questionList);
vh.reponseList = (TextView) view.findViewById(R.id.reponseList);
vh.difficulteList = (TextView) view.findViewById(R.id.difficultList);
vh.Supprimer = (Button) view.findViewById(R.id.buttonDelete);
vh.Modifier = (Button) view.findViewById(R.id.buttonModifier);
//END EDIT
vh.idList.setText(cursor.getString(cursor.getColumnIndex(stock._ID)));
vh.themeList.setText(cursor.getString(cursor.getColumnIndex(stock.THEME)));
vh.questionList.setText(cursor.getString(cursor.getColumnIndex(stock.QUESTION)));
vh.reponseList.setText(cursor.getString(cursor.getColumnIndex(stock.REPONSE)));
vh.difficulteList.setText(cursor.getString(cursor.getColumnIndex(stock.DIFFICULTE)));
vh.Supprimer.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
View parentView = (View)v.getParent();
TextView idList = (TextView) parentView.findViewById(R.id.idList);
int id = Integer.parseInt(idList.getText().toString());
deleteOneCard(id);
Toast.makeText(container.getContext(), "Suppression de "+id, Toast.LENGTH_SHORT).show();
}
});
vh.Modifier.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
View parentView = (View)v.getParent();
TextView idList = (TextView) parentView.findViewById(R.id.idList);
TextView themeList = (TextView) parentView.findViewById(R.id.themeList);
themeList.setFocusable(true);
themeList.requestFocus();
/*TextView questionList = (TextView) parentView.findViewById(R.id.questionList);
TextView reponseList = (TextView) parentView.findViewById(R.id.reponseList);
TextView difficulteList = (TextView) parentView.findViewById(R.id.difficultList);*/
int id = Integer.parseInt(idList.getText().toString());
Toast.makeText(container.getContext(), "bouton Modifier pour "+id, Toast.LENGTH_SHORT).show();
}
});
