Question

我有一个TextView用于描述，另一个用于当前步骤“app for 食谱“

当我将设备的方向更改为横向并再次返回纵向模式时，会发生此问题（TextView中的文本与另一个TextView不同，尽管有单个TextView且发生此重叠）请参阅附加图像。

This when i go landscape and returned to portrait again

    ButterKnife.bind(this, root);

        return root;
    }
    steps = bundle.getParcelableArrayList("steps");
    currentIndex = bundle.getInt("current");

    show();

    back.setOnClickListener(this);
    next.setOnClickListener(this);

    return root;
}

@Override
public void onClick(View v) {
    int id = v.getId();

    if (id == R.id.back_button) {
        currentIndex--;
        show();
    } else if (id == R.id.next_button) {
        currentIndex++;
        show();
    }

}


public void show() {
    if (currentIndex <= 0) {
        back.setVisibility(GONE);
    } else {
        back.setVisibility(View.VISIBLE);
    }
    if (listener != null) {
        listener.setCurrent(currentIndex);
    }
    if (currentIndex >= steps.size() - 1) {
        next.setVisibility(GONE);
    } else {
        next.setVisibility(View.VISIBLE);
    }

    description.setText(steps.get(currentIndex).getDescription());
    current.setText((currentIndex + 1) + "/" + steps.size());

}

您的活动会在轮播时重新创建。片段管理器将原始片段存储在实例状态中，但我假设您在活动的onCreate()中添加了一个新片段。因此，您将已恢复的片段和新片段放在一起。

如果savedInstanceState为null，则可能只会添加新片段。
