android change listview font and color

问题:

I've found loads of different ways of accomplishing this but I'm not sure what's the best for my scenario.

This is my Java code for the listview:

ListView lv;
lv = (ListView) findViewById(R.id.favList);

This is the xml code for the list:

<ListView
        android:id="@+id/favList"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="40dp"
        android:layout_marginLeft="30dp"
        android:layout_marginRight="30dp"
        android:layout_marginTop="20dp"
        android:background="@android:color/transparent"
        android:cacheColorHint="@android:color/transparent"
        android:listSelector="@android:color/transparent" >
    </ListView>

For a text view I would add:

final Typeface fontList = Typeface.createFromAsset(assets, "optima-extra-black.ttf");
lv.setTypeface(fontList);

But this doesn't work for listviews. How do I change my font in this case?

Oke I'm almost there... I need to access my assets but I can't from within my custom adapter. I tried using final AssetManager assets = this.getAssets(); but that won't get me any further..

How to tackle this?

    class Myadapter extends BaseAdapter {

    LayoutInflater lif;
    ImageView sideArrow;
    TextView tv;


    public Myadapter(Context ctx) {
        lif = (LayoutInflater) ctx
                .getSystemService(LAYOUT_INFLATER_SERVICE);

    }

    @Override
    public int getCount() {

        return favarets.size();
    }

    @Override
    public Object getItem(int position) {
        return position;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        View vi = convertView;
        if (convertView == null)
            vi = lif.inflate(R.layout.inflate, null);
        sideArrow = (ImageView) vi.findViewById(R.id.imageViewsidemark);

        tv = (TextView) vi.findViewById(R.id.textFav);
        tv.setText(favarets.get(position));
        final AssetManager assets = this.getAssets();
        final Typeface tvFont = Typeface.createFromAsset(assets, "OPTIMA.TTF");
        tv.setTypeface(tvFont);

        tv.setTextColor(Color.BLACK);

        return vi;

I found out the solution :D

    public class Myadapter extends BaseAdapter {

    AssetManager assetManager = getAssets(); 

    LayoutInflater lif;
    ImageView sideArrow;
    TextView tv;


    public Myadapter(Context ctx) {
        lif = (LayoutInflater) ctx.getSystemService(LAYOUT_INFLATER_SERVICE);


    }

    @Override
    public int getCount() {

        return favarets.size();
    }

    @Override
    public Object getItem(int position) {
        return position;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        View vi = convertView;
        if (convertView == null)
            vi = lif.inflate(R.layout.inflate, null);
        sideArrow = (ImageView) vi.findViewById(R.id.imageViewsidemark);


        tv = (TextView) vi.findViewById(R.id.textFav);
        tv.setText(favarets.get(position));

        final Typeface tvFont = Typeface.createFromAsset(assetManager, "OPTIMA.TTF");
        tv.setTypeface(tvFont);
        tv.setTextColor(Color.BLACK);

        return vi;
    }

}

The list view itself isn't responsible for drawing the items, it uses an adapter to create the list items. This adapter creates a view to display the list item when required. To change the font used to display the list item, you have to change the adapter to return a view with the new font. This can be done in the Adapter.getView method. If you are currently using a standard Adapter implementation, you may need to subclass it (or completely replace it).

you need to create a custom adapter.

check this answer

and then have a custom xml too.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content">
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/textView"
    android:textSize="20px" android:paddingTop="10dip" android:paddingBottom="10dip"/>
</LinearLayout>

then set the custom adapter to your listview.

listAdapter = new CustomListAdapter(YourActivity.this , R.layout.custom_list , mList);
mListView.setAdapter(listAdapter);

Just set it to the TextView which you are inflating set the typeface in adapter or in the xml layout.
