如何解决如何在Android中将视图添加到自定义ListView？
| 我在具有progressbar的android活动中制作了自定义listview。在该列表视图的顶部，还有另一个进度条，该进度条显示当月的一天过去时的进度。现在我想根据自定义列表视图中具有四个进度条的月份进度条的进度设置一个条。请参阅所附图片。 月份进度条的进度和我们放在列表视图进度栏中的进度条应位于同一位置，这意味着对齐，并且当顶部进度随着日期的过去而增加时，我们放置的此进度条应移动。 在布局文件中，我使用了LinearLayout，我想将其放置在栏上。<?xml version=\"1.0\" encoding=\"utf-8\"?>

mTextOne.setText(mEntry.getValue());
mRight = (TextView) convertView.findViewById(R.id.RightText);
mRight.setText(mEntry.getValueOne());
return convertView;
}
}
解决方法
您应该在
getView
removeAllViews
mLinearLayout = (LinearLayout) convertView.findViewById(R.id.PuttingBar);
mLinearLayout.removeAllViews();
View mView = new View(mContext);
LinearLayout
addView
PuttingBar
