我使用下面的代码获取三个字符串和一个整数，以使用自定义数组适配器和自定义类在列表视图中创建文本视图

它不适合我。请指导我。
答案 0 :(得分：0)
更改
englishNumber.setText(currentWord.getmEnglishNumber());
到
englishNumber.setText(currentWord.getmEnglishNumber()+"");
的TextView＃的setText
public final void setText(@StringRes int resid) {
setText(getContext().getResources().getText(resid));
}
