I finished my app and would add some features. Ad example the user can change the text size. So i have Have created an activity where you can select the text size. Here is the code:
public class Options extends AppCompatActivity {
RadioButton r1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_options);
RadioGroup rdgroup = (RadioGroup)findViewById(R.id.radioGroup);
r1 = (RadioButton)findViewById(R.id.radioButton);
r1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ClasseDiAppoggio.setSize(10);
}
});
}
}
This is the code of class ClasseDiAppoggi:
public class ClasseDiAppoggio {
private static float size = 20;
public static void setSize(float sizex){
size = sizex;
}
public static float getSize(){
return size;
}
}
And here is the code of the Adapter:
public class MyAdapter extends ArrayAdapter<Model> {
static View globalView;
private TreeSet mSeparatorsSet = new TreeSet();
public final List<Model> list;
private final Activity context;
public String textToSay;
private int mCurrentTtsPosition = -1;
Boolean testCheck = false;
public MyAdapter(Activity context, List<Model> list) {
super(context, R.layout.row, list);
this.context = context;
this.list = list;
}
@Override
public int getItemViewType(int position) {
if (list.get(position).getVersion() == 0) {
return 0;
}
if (list.get(position).getVersion() == 2) {
return 2;
}
if (list.get(position).getVersion() == 3) {
return 3;
}
if (list.get(position).getVersion() == 4) {
return 4;
}
if (list.get(position).getVersion() == 5) {
return 5;
}
return 1;
}
@Override
public int getViewTypeCount() {
return 6;
}
public void onStopTts(){
mCurrentTtsPosition = -1;
notifyDataSetChanged();
}
static class ViewHolder {
public TextView text;
public TextView text2;
public CheckBox checkbox;
public TextView textSeparator;
public Button btncheck;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = null;
if (this.getItemViewType(position)== 0){
if (convertView == null) {
LayoutInflater inflator = context.getLayoutInflater();
viewHolder = new ViewHolder();
convertView = inflator.inflate(R.layout.title_row, null);
viewHolder.textSeparator = (TextView) convertView.findViewById(R.id.textView);
convertView.setTag(viewHolder);
convertView.setTag(R.id.textView, viewHolder.textSeparator);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.textSeparator.setText(list.get(position).getName());
return convertView;
} else if (this.getItemViewType(position)== 2){
if (convertView == null) {

convertView.setTag(R.id.textView, viewHolder.textSeparator);
} else {

}
viewHolder.textSeparator.setText(list.get(position).getName());
return convertView;

final ViewHolder finalViewHolder = viewHolder;
viewHolder.btncheck.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
for (Model i: list) {
if (i.getVersion() == 1) {
if (!i.isSelected()) {
testCheck = false;
}
}
}
if(testCheck){
OneFragment.startSpeak("è stato controllato tutto");

});
return convertView;

if (position == mCurrentTtsPosition){

So the code works, but the problem is that the size change when i scroll the listview. So to so changes in the code should scroll down and after scroll up so that i can see the changes of text size. How can i do that the changes are immediate? Thanks, and sorry for the bad english.
try youView.invalidate() that should work.
You could also try ListView.invalidateViews() . this forces the listview to redraw its items. call it when you change the textSize.
In your case you can use listView.invalidateViews() in onResume() of the fragment_one. or to simplify you can just shift your listView.setAdapter() to onResume() then it will work
