Question

我尝试更改位于自定义布局中的textview的typeFace。当将text设置为textview时，textview变为不可见，但在原始布局文件中我可以看到typeFace已更改但未以编程方式反映....请帮我解决此问题

list_row.xml //自定义布局

Answer 1

检查您的ttf文件是否位于assets目录中。

然后我建议你将ttf“CROCHET PATTERN.ttf”重命名为“CrochetPattern.ttf”，也许这里的“空间”是个麻烦。

编辑： 我没有意识到你在ListView。您需要在适配器的TypeFace方法中设置newView。所以在这里你需要覆盖CursorAdapter。就像在这段代码中一样：

public class CustomCursorAdapter extends CursorAdapter {
    private Context context;
    LayoutInflater mInflater;

    public AreaCursorAdapter(Context context, Cursor c) {
        // that constructor should be used with loaders.
        super(context, c, 0);
        mInflater = LayoutInflater.from(context);
    }


    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        // put the data on your views           

    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        View v = mInflater.inflate(R.layout.list_row, parent, false);
        Typeface font;
        TextView txtDaysRemainig = (TextView)view.findViewById(R.id.txtview_days_left);
        font=Typeface.createFromAsset(getAssets(), "CrochetPattern.ttf");
        txtDaysRemainig.setTypeface(font);
        // edit: no need to call bindView here. That's done automatically
        return v;
    }

}

因为在您从未在任何地方附加的布局修改TextView之前。

并替换：

adapter=new CustomSimpleCursor(this, R.layout.list_row, cursor, from, to);

通过

adapter = new CustomCursorAdapter(this, cursor);

Answer 2

在设置字体

后尝试手动设置txtDatsRemaining.setText("365");文本

来自assets文件夹的字体文件，设置为自定义布局的textview是不可见的android
