我正在开发与tinder类似的应用，但这不是约会应用。
我正在使用卡片查看功能，遇到了一些我无法解决的错误。
这是我已成功编码（暂时）的应用的名片查看功能。
主布局（卡的顶部）包含配置文件图像和用户名。 第二个是包含文本字段的弹出窗口。
用户将在卡视图中看到其他用户的详细信息。
我可以选择通过触摸“更多信息”按钮来查看有关另一个用户的更多信息。 选择更多信息按钮后，弹出窗口将设置为动画
用户可以通过触摸图标以减少“更多信息”显示来返回默认视图。
目前，执行滑动后，我在卡视图的弹出窗口中显示的信息面临问题。 问题是，执行刷卡操作并显示新用户卡后，弹出窗口中的文本字段需要无缝更新。
用户信息通过Firebase实时数据库

popupWindow2.setOutsideTouchable(false);
final String yourString = userName;
final TextView popupText = (TextView) popupView2.findViewById(R.id.textView13j);
popupText.setText(yourString);
// show the popup window
// which view you pass in doesn't matter, it is only used for the window tolken
popupWindow2.setAnimationStyle(R.style.styleAnimationResourceCardviewpopup);
popupWindow2.showAtLocation(popupView2, Gravity.BOTTOM, 0, 0);
// dismiss the popup window when touched
btn.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
popupWindow2.dismiss();
return true;
}
});
}
我正在寻找有关在弹出窗口中无缝更新用户个人资料数据的建议。
值从下面的代码存储在“ userName”变量中
flingContainer.setOnItemClickListener(new SwipeFlingAdapterView.OnItemClickListener() {
@Override
public void onItemClicked(int itemPosition, Object dataObject) {
cardsxx obj = (cardsxx) dataObject;
String userId = obj.getUserId();
DatabaseReference userDb3 = usersDb4.child(obj.getUserId());
userDb3.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
if (dataSnapshot.exists()){
if (dataSnapshot.child("email").getValue() != null){
useremail = dataSnapshot.child("email").getValue().toString();
userName=dataSnapshot.child("name").getValue().toString();
userJob = dataSnapshot.child("industry").getValue().toString();
}
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
});

答案 0 :(得分：0)
这里的问题是，当您单击“更多信息按钮”时，您无法传递最新的“用户名”值。
一种解决方案是：我假设您正在使用recyclerview / listview来显示其他用户信息。如果您使用的是recycler-view，则还必须具有它的适配器和它的viewHolder。适配器具有函数“ onBindViewHolder”，它将解析每个视图和数据对象，并且您需要使用此方法分配数据以进行视图。现在，您应该在此方法中实现“ button4infoor”的“ setOnClickListener”，并将其从.xml视图中删除。因此，下面提到的逻辑应该放在'onClick（）'方法中
DatabaseReference userDb3 = usersDb4.child(obj.getUserId());
userDb3.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
if (dataSnapshot.exists()){
if (dataSnapshot.child("email").getValue() != null){
useremail = dataSnapshot.child("email").getValue().toString();
userName=dataSnapshot.child("name").getValue().toString();
userJob = dataSnapshot.child("industry").getValue().toString();
animateViewFromBottomToTop(useremail, userName, userJob);
}
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
并将用户相关的值传递给函数“ animateViewFromBottomToTop”并相应地设置视图。但是，如果您使用的是recyclerview / listview，那么所有这些都将起作用。让我知道您是否还有其他查询。
