在我的GridView中使用BaseAdapter，字号有时很大，有时很小

public class MyAdapter extends BaseAdapter {
    private Context mContext;
    private List<String> mData;
    private boolean mIsLargeFont;

    public MyAdapter(Context context, List<String> data, boolean isLargeFont) {
        mContext = context;
        mData = data;
        mIsLargeFont = isLargeFont;
    }

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

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

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        TextView textView;
        if (convertView == null) {
            textView = new TextView(mContext);
            textView.setLayoutParams(new GridView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
        } else {
            textView = (TextView) convertView;
        }

        String item = mData.get(position);
        textView.setText(item);

        if (mIsLargeFont) {
            textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 20); // 设置字号为20sp
        } else {
            textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 12); // 设置字号为12sp
        }

        return textView;
    }
}

List<String> data = new ArrayList<>();
data.add("Item 1");
data.add("Item 2");
data.add("Item 3");

boolean isLargeFont = true; // 是否使用大字号

MyAdapter adapter = new MyAdapter(context, data, isLargeFont);
gridView.setAdapter(adapter);
