Question

我的课程里面有一个ListMenuAdapter：

ListMenuAdapter adapter = new ListMenuAdapter(this, R.layout.listmenu_item, listMenuData);

问题是：我无法从R.layout.listmenu_item访问textview。我需要访问它，因为我想更改其字体。

这是完整的代码：

 @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);



    ListMenu listMenuData[] = new ListMenu[]
    {
        new ListMenu(R.drawable.final_test, "Hello World ^_^", getHighScore(1)),
        new ListMenu(R.drawable.introduction, "Introduction", getHighScore(1)),
        new ListMenu(R.drawable.input_output, "Input - Output", getHighScore(2))
    };


    ListMenuAdapter adapter = new ListMenuAdapter(this, R.layout.listmenu_item, listMenuData);

    listMenu = (ListView)findViewById(R.id.listMenu);

    View header = (View)getLayoutInflater().inflate(R.layout.listmenu_header, null);
    //I TRIED THIS FOR ACCESSING THE TEXTVIEW, BUT NO LUCK
    View titles = (View)getLayoutInflater().inflate(R.layout.listmenu_item, null);

    Typeface customFont = Typeface.createFromAsset(this.getAssets(), "Androgyne_TB.otf");

    //WORKING
    txtHeader = (TextView)header.findViewById(R.id.txtHeader);
    //NOT WORKING
    txtTitle = (TextView) titles.findViewById(R.id.txtTitle);

    //WORKING    
    txtHeader.setTypeface(customFont);
    //NOT WORKING
    txtTitle.setTypeface(customFont);

    listMenu.addHeaderView(header);

    listMenu.setAdapter(adapter);
    listMenu.setOnItemClickListener(this);
}

我试图通过R.layout.listmenu_item来充分访问Textview：

View titles = (View)getLayoutInflater().inflate(R.layout.listmenu_item, null);

但它仍无效（请参阅上面的完整代码）：D

已编辑：

这是ListMenuAdapter GetView方法：

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    View row = convertView;
    MenuHolder holder = null;

    if(row == null)
    {
        LayoutInflater inflater = ((Activity)context).getLayoutInflater();
        row = inflater.inflate(layoutResourceId, parent, false);

        holder = new MenuHolder();
        holder.imgMenuIcon = (ImageView)row.findViewById(R.id.imgMenuIcon);
        holder.txtTitle = (TextView)row.findViewById(R.id.txtTitle);
        //holder.txtHighScore = (TextView)row.findViewById(R.id.txtHighScore);

        //holder.txtHighScore.setTextColor(Color.RED);
        holder.rtbHighScore = (RatingBar) row.findViewById(R.id.rtbHighScore);
        //holder.rtbHighScore.setNumStars(5);
        //holder.rtbHighScore.setEnabled(false);

        row.setTag(holder);
    }
    else holder = (MenuHolder)row.getTag();

    ListMenu menu = listmenu[position];
    holder.imgMenuIcon.setImageResource(menu.icon);
    holder.txtTitle.setText(menu.title);
    //holder.txtHighScore.setText("High Score : "  + menu.highscore);
    holder.rtbHighScore.setRating(menu.highscore/20);
    return row;
}

Answer 1

您可以在适配器的getView方法中获得对textview的引用。

holder.txtTitle =（TextView）row.findViewById（R.id.txtTitle）;

在此之后，您可以设置字体

Answer 2

holder.txtTitle.setText(menu.title);

在getview尝试之后

holder.txtTitle.setTypeFace(face);

Answer 3

作为我在您的问题上留下的评论，您可以在getView()行下的holder.txtTitle.setText(menu.title);方法中为标题文字视图设置typeFace，如下所示：

要获取字体实例表单Assets，您需要将Context参数传递给您的适配器 - 我认为您已经这样做了 - 然后使用该实例创建字体，就像在onCreate()中一样或检查编辑如下：

修改

Typeface customFont = Typeface.createFromAsset(getContext().getAssets(),"Androgyne_TB.otf");

然后你可以将typeFace设置如下：

holder.txtTitle.setTypeFace(customFont);

来自ListMenuAdapter的setTypeface textview
