在android自定义列表视图中展开textview高度

我正在使用带有文本视图的自定义列表视图。当单击文本视图时，必须根据可用文本增加行高。例如，当holder.asr_tv_Content按下当前行，在那里与其他控件高度具有沿按压以增大在android自定义列表视图中展开textview高度

为什么不是所有那些浪费的列表而是一个单独的'ArrayList mRemarks;'。此外，避免挂在上下文，除非关键 –

设置视图高度WRAP_CONTENT（和做同样为它的祖先）

当告诉你默认的文本，显示它的一小部分

private static final int MAX_LEN = 22; //choose this yourself 

if (text.length() > MAX_LEN) { 
    textView.setText(text.substring(0, MAX_LEN) + "..."); 
} else { 
    textView.setText(text); 
}

随后的onClick，与全价值

再次更新
