android - 如何在 ListView 中更改每个列表项的前面

我有5种字体样式（Typeface），并希望向用户输入5次到不同字体样式的ListView 5次。
以下是我尝试过的代码。

 public void ShowTextStyles(String inputText, int color){
    final Dialog dialog = new Dialog(EditImageActivity.this);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.textstylelayout);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    // Array of strings...
    final String[] textStyles={"Gobold Bold.ttf","beyond_wonderland.ttf"};
    final String[] mobileArray = {inputText,inputText,inputText,inputText,inputText,inputText,inputText,inputText,inputText,inputText};
    ArrayAdapter adapter = new ArrayAdapter<String>(EditImageActivity.this,
            R.layout.text_style_list, mobileArray);

    ListView listView = (ListView) dialog.findViewById(R.id.mobile_list);
    listView.setAdapter(adapter);

    // Set an item click listener for ListView
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            // Get the selected item text from ListView
            String selectedItem = (String) parent.getItemAtPosition(position);

            // Display the selected item text on TextView




        }
    });
    dialog.setCancelable(true);
    dialog.show();


}

最佳答案

创建自定义适配器并将其用于您的列表视图：

public class TestAdapter extends BaseAdapter {
    private Context context;
    private List<String> appData;
    String[] fontFiles = {"Gobold Bold.ttf", "beyond_wonderland.ttf"}; // add more fonts if wish more styles

public TestAdapter(Context context, List<String> appData) {
    this.context = context;
    this.appData = appData;
}

@Override
public int getCount() {
    return appData.size();
}

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

@Override
public long getItemId(int position) {
    return 0;
}

private class ViewHolder {
    TextView tv_item;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    ViewHolder holder = null;
    if (convertView == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.list_app, null);
        holder = new ViewHolder();
        holder.tv_item = convertView.findViewById(R.id.tv_item);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.tv_item.setText(appData.get(position));
    Typeface typeface;

    // change this condition according to your need
    if (position == 0){
        typeface = Typeface.createFromAsset(context.getAssets(), fontFiles[0]);
    }else {
        typeface = Typeface.createFromAsset(context.getAssets(), fontFiles[1]);
    }

    holder.tv_item.setTypeface(typeface);

    return convertView;
}
}
