在列表视图的Android的EditText失去焦点的要求notifydatachanged [英] Android edittext in listview loses focus on calling notifydatachanged
问题描述
我有一个列表视图中的几个的EditText。我有一个更新的数据模型的价值，也是的EditText的背景时，重点是通过调用notifydatachanged失去的EditText一个通用的FocusListener。问题是，如果的EditText之一是保持专注，当我触碰下一个EditText上，它获得关注，然后瞬间失去焦点。我怀疑这是由于notifydatachanged方法调用导致所有视图重绘，之后焦点将丢失。有没有人有任何建议或解决的问题？谢谢你。
I have a few edittext within a listview. i have a generic focuslistener on the edittext that updates the value of the data model and also the background of the edittext when focus is lost by calling notifydatachanged . The problem is that if one of the edittext is holding focus, when i touch the next edittext, it gains focus momentarily then loses focus. I suspect it is due to the notifydatachanged method call that is causing all views to be redrawn, after which the focus is lost. Does anyone have a suggestion or work around on the issue? Thanks.
推荐答案
它确实发生了，因为所有的意见都重新绘制，所以无论行用于集中编辑的文本再presenting现在是一个完全不同的对象。在您的适配器设置一个变量：int currentlyFocusedRow;
It is indeed happening because all the views are redrawn, so the edit text representing whatever row used to be focused is now a completely different object. Set a variable in your adapter: int currentlyFocusedRow;
在getView为您的适配器：添加onFocusChanged侦听器，每个编辑的文本和当编辑文本获得焦点，设置currentlyFocusedRow =无论行聚焦编辑文本恰好是在另外设置的任何修改文本在currentlyFocusedRow来。可重点关注。
in getView for your adapter: Add an onFocusChanged listener to each edit text and when that edit text gains focus, set currentlyFocusedRow = whatever row the focused edit text happens to be in. Also set any edit text that is in the currentlyFocusedRow to be focused.
