问题
I am new to android and using custom font for listview.I did not know how to use the typeface in a list view .I also tried with different examples but cant solve my problem .Here is my code
public class HomeScreen extends ListActivity {
private static final int QUICK_START_INDEX =0;
private static final int CUSTOM = 1;
private static final int CALL_LIST = 2;
private static final int CALENDAR = 3;
private static final int TEMPLATES=4;
private static final int USER_GUIDE = 5;
static final String[] LIST =
new String[] { "QuickStart", "Custom", "CallList", "Calendar","Templates","UserGuide"};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new MobileArrayAdapter(this, LIST));
/*Typeface font = Typeface.createFromAsset(getAssets(), "earthkid.ttf"); */
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
//get selected items
String selectedValue = (String) getListAdapter().getItem(position);
/*Toast.makeText(this, selectedValue, Toast.LENGTH_SHORT).show();*/
if(position==QUICK_START_INDEX){
startActivity(new Intent(HomeScreen.this,ConfDialer.class));
}
}
}
MobileArrayAdapter.java
public class MobileArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
public MobileArrayAdapter(Context context, String[] values) {
super(context, R.layout.list_home, values);
this.context = context;
this.values = values;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_home, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.label);
ImageView imageView = (ImageView) rowView.findViewById(R.id.logo);
textView.setText(values[position]);
// Change icon based on name
String s = values[position];
System.out.println(s);
if (s.equals("QuickStart")) {
imageView.setImageResource(R.drawable.quick_strat);
} else if (s.equals("Custom")) {
imageView.setImageResource(R.drawable.customize);
} else if (s.equals("CallList")) {
imageView.setImageResource(R.drawable.call_list);
} else if(s.equals("Calendar")){
imageView.setImageResource(R.drawable.calendar);
} else if(s.equals("Templates")){
imageView.setImageResource(R.drawable.templates);
}
else{
imageView.setImageResource(R.drawable.user_guide);
}
return rowView;
}
}
Could any one provide solution for this.
回答1:
Try this...
You can override the getView() when creating your Adapter in Activity, for example of a SimpleAdapter with name and title.
//global declaration
ListAdapter adapter;
adapter = SimpleAdapter(getActivity(), your_list, R.layout.your_list_items, new String[]{"Name", "Title"}, new int[]{R.id.name, R.id.title}){
@Override
public View getView(int position, View convertView, ViewGroup parent) {
v = convertView;
if(v == null){
LayoutInflater li = (LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = li.inflate(R.layout.interview_list_items, null);
TextView titleText= (TextView) v.findViewById(R.id.title);
TextView nameText= (TextView) v.findViewById(R.id.name);
childFont = Typeface.createFromAsset(getActivity().getAssets(),"fonts/Roboto-Light.ttf");
titleText.setTypeface(childFont);
nameText.setTypeface(childFont);
return super.getView(position, v, parent);
}
};
Or try it in Adapter class like this...
public class MobileArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
private Typeface tf;
public MobileArrayAdapter(Context context, String[] values) {
super(context, R.layout.list_home, values);
this.context = context;
this.values = values;
this.tf = Typeface.createFromAsset(context.getAssets(), "fonts/Roboto-Light.ttf"); //initialize typeface here.
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_home, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.label);
ImageView imageView = (ImageView) rowView.findViewById(R.id.logo);
textView.setTypeface(tf); // set typeface here
textView.setText(values[position]);
// Change icon based on name
String s = values[position];
System.out.println(s);
if (s.equals("QuickStart")) {
imageView.setImageResource(R.drawable.quick_strat);
} else if (s.equals("Custom")) {
imageView.setImageResource(R.drawable.customize);
} else if (s.equals("CallList")) {
imageView.setImageResource(R.drawable.call_list);
} else if(s.equals("Calendar")){
imageView.setImageResource(R.drawable.calendar);
} else if(s.equals("Templates")){
imageView.setImageResource(R.drawable.templates);
}
else{
imageView.setImageResource(R.drawable.user_guide);
}
return rowView;
}
}
app directory structure
回答2:
use this code
In Your MobileArrayAdapter
class MobileArrayAdapter extends ArrayAdapter<CharSequence>{
Typeface tf;
public MobileArrayAdapter(Context context, String[] values,String FONT) {
tf = Typeface.createFromAsset(context.getAssets(), FONT);
}
From Where You Are calling your adapter
listAdapter = new MobileArrayAdapter(this, R.layout.custom_list_text, R.array.arrayName, "name_of_font.ttf");
回答3:
you just need to change the font in this layout "R.layout.list_home". Because list_home is layout which is working as a single row. So if you changes it, it will affects the color/text/style of listview too.
回答4:
Put a custom font file .ttf in assets folder and use the below code to change font
text.setTypeface(Typeface.createFromAsset(getAssets(), "/*path to your font file */"));
Path would be the path in assets. If file is in assets folder only the use only the file name with extension.
Like
text.setTypeface(Typeface.createFromAsset(getAssets(), "arial.ttf"));
回答5:
Use
setTypeface(Typeface)
in Textview object.
回答6:
This is my custom adapter how to call and which parameters are give in my call activity.
public class CustomData extends ArrayAdapter<CharSequence>
{
Context context;
int layoutResourceId;
CharSequence data[] = null;
Typeface tf;
public CustomData(Context context, int layoutResourceId, CharSequence[] data, String FONT) {
super(context, layoutResourceId, data);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.data = data;
tf = Typeface.createFromAsset(context.getAssets(), FONT);
}
}
回答7:
I use this code in my Adapter class and it work:
public class MyAdapter extends BaseAdapter {
private Context context;
private ArrayList<Item> item;
public MyAdapter(Context context, ArrayList<Item> item) {
this.context = context;
this.item = item;
}
@Override
public int getCount() {
return item.size();
}
@Override
public Object getItem(int i) {
return item.get(i);
}
@Override
public long getItemId(int i) {
return i;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
if (view == null) {
view = LayoutInflater.from(context).inflate(R.layout.list_header, viewGroup, false);
}
Typeface MyFont= Typeface.createFromAsset(context.getAssets(), "Arial.ttf");
TextView txtTitle = view.findViewById(R.id.txtTitle);
txtTitle.setTypeface(MyFont);
}
}
