Android自定义输入法横屏模式时有提取框问题

public class PinyinInput extends InputMethodService {
...
    @Override
    public boolean onEvaluateFullscreenMode() {
        return false;
    }
    ...
}

• onEvaluateFullscreenMode不要改写!
• 不能return null哦 不然会有异常!

    @Override
    public View onCreateExtractTextView() {
        return super.onCreateExtractTextView();
    }

• 提取框的UI改写

@Override
public View onCreateExtractTextView() {
    View extractedView = super.onCreateExtractTextView();
    ExtractEditText editText = extractedView.findViewById(android.R.id.inputExtractEditText);
    editText.setTypeface(myTypeFace);
    editText.setTextSize(myTextSize);
    return extractedView;
}
