根据 TextView 的高度设置 ImageView 的高度

Question

我有一个 ImageView，它应该具有 TextView 的高度，这是我正在使用的代码，但它总是 returns 0:

    @Override
public void onBindViewHolder(@NonNull viewHolder holder, final int position) {


    holder.abstractText.setText(events.get(position).abstractTExt);

    Rect bounds = new Rect();
    Paint textPaint = holder.abstractText.getPaint();
    textPaint.getTextBounds((String) holder.abstractText.getText(),0,holder.abstractText.getText().length(),bounds);

    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, bounds.height());
    holder.borderImage.setLayoutParams(layoutParams);
    Log.d("-------------borderHe", String.valueOf((holder.abstractText.getLineHeight() * holder.abstractText.getLineCount())));
}

我该怎么做？提前致谢！

它返回零，因为您的视图尚未创建，因此您需要通过 post 方法使用以下代码。首先需要计算TextView的高度，然后应用到layout，

holder.abstractText.post(new Runnable() {
            @Override
            public void run() {
                RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, holder.abstractText.getHeight());
                holder.borderImage.setLayoutParams(layoutParams);     
            }
        });
