Question

我有一个ExpandableListView，其中包含RelativeLayout个LinearLayout个TextViews个EditText，其中包含// ChildView views badScoreView = convertView.findViewById(R.id.qwedit_main_badView); mediocreScoreView = convertView.findViewById(R.id.qwedit_main_mediocreView); goodScoreView = convertView.findViewById(R.id.qwedit_main_goodView); worldclassScoreView = convertView.findViewById(R.id.qwedit_main_wcView); badScoreTextView = (TextView) convertView.findViewById(R.id.qwedit_main_badTextView); mediocreScoreTextView = (TextView) convertView.findViewById(R.id.qwedit_main_mediumTextView); goodScoreTextView = (TextView) convertView.findViewById(R.id.qwedit_main_goodTextView); worldClassScoreTextView = (TextView) convertView.findViewById(R.id.qwedit_main_worldclassTextView); questionCommentEditText = (EditText) convertView.findViewById(R.id.qwedit_main_commentEditText); // TODO: TextView score subcategory setters badScoreView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO: add logic to change score subCategoryScore = 1; badScoreView.setBackgroundColor(Color.parseColor("#eca9a7")); mediocreScoreView.setBackgroundColor(Color.parseColor("#f0ad4e")); goodScoreView.setBackgroundColor(Color.parseColor("#5cb85c")); worldclassScoreView.setBackgroundColor(Color.parseColor("#0275d8")); questionCommentEditText.clearFocus(); } }); mediocreScoreView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO: add logic to change score subCategoryScore = 2; badScoreView.setBackgroundColor(Color.parseColor("#d9534f")); mediocreScoreView.setBackgroundColor(Color.parseColor("#f7d6a6")); goodScoreView.setBackgroundColor(Color.parseColor("#5cb85c")); worldclassScoreView.setBackgroundColor(Color.parseColor("#0275d8")); questionCommentEditText.clearFocus(); } }); goodScoreView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO: add logic to change score subCategoryScore = 3; badScoreView.setBackgroundColor(Color.parseColor("#d9534f")); mediocreScoreView.setBackgroundColor(Color.parseColor("#f0ad4e")); goodScoreView.setBackgroundColor(Color.parseColor("#addbad")); worldclassScoreView.setBackgroundColor(Color.parseColor("#0275d8")); questionCommentEditText.clearFocus(); } }); worldclassScoreView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO: add logic to change score subCategoryScore = 4; badScoreView.setBackgroundColor(Color.parseColor("#d9534f")); mediocreScoreView.setBackgroundColor(Color.parseColor("#f0ad4e")); goodScoreView.setBackgroundColor(Color.parseColor("#5cb85c")); worldclassScoreView.setBackgroundColor(Color.parseColor("#80baeb")); questionCommentEditText.clearFocus(); } });，它会提取问题的答案并将该问题从1分配给-4（分别为坏，平庸，良好和世界级），最后为<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content"> <LinearLayout android:id="@+id/qwedit_elv_item_score_container" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="wrap_content"> <LinearLayout android:id="@+id/qwedit_main_badView" android:layout_width="232.5dp" android:layout_height="145.3dp" android:background="@color/badScore"> <TextView android:id="@+id/qwedit_main_badTextView" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:textColor="@color/white" android:textSize="20sp" android:text="Bad"/> </LinearLayout> <LinearLayout android:id="@+id/qwedit_main_mediocreView" android:layout_width="232.5dp" android:layout_height="145.3dp" android:background="@color/mediocreScore"> <TextView android:id="@+id/qwedit_main_mediumTextView" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:textColor="@color/white" android:textSize="20sp" android:text="Mediocre"/> </LinearLayout> <LinearLayout android:id="@+id/qwedit_main_goodView" android:layout_width="232.5dp" android:layout_height="145.3dp" android:background="@color/goodScore"> <TextView android:id="@+id/qwedit_main_goodTextView" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:textColor="@color/white" android:textSize="20sp" android:text="Good"/> </LinearLayout> <LinearLayout android:id="@+id/qwedit_main_wcView" android:layout_width="232.5dp" android:layout_height="145.3dp" android:background="@color/worldclassScore"> <TextView android:id="@+id/qwedit_main_worldclassTextView" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:textColor="@color/white" android:textSize="20sp" android:text="World Class"/> </LinearLayout> </LinearLayout> <EditText android:id="@+id/qwedit_main_commentEditText" android:layout_width="930dp" android:layout_height="wrap_content" android:layout_below="@+id/qwedit_elv_item_score_container" android:cursorVisible="false" android:focusable="true" android:focusableInTouchMode="true" android:inputType="text" android:hint="Comments"/> </RelativeLayout>用户留下评论他们为什么评分得分的问题。当用户单击分数框时，背景会更改颜色以突出显示所选分数，并将其他分数框颜色设置回其默认颜色，以显示它们不再被选中。下面是我的Java来展示它是如何工作的：

EditText

布局，以防相关：

onClick()

出于某种原因，当用户按下CustomListViewAdapter并添加文本或点击时，按钮ExpandableListView功能不再起作用（即，它们不再改变颜色）。

这是由焦点引起的吗？ javacode onClick函数位于CREATE TABLE [DB] ( ServerId INT, [DBID] INT, DBName varchar(255), Createtime DATETIME, LastCheckTime DATETIME ) INSERT INTO [DB] VALUES (1,1, 'DB1', '2010-09-10', '2013-09-01'), (1,2, 'DB2', '2010-09-10', GETDATE()), (1,3, 'DB3', '2010-09-12', GETDATE()), (1,4, 'DB4', '2011-09-13', GETDATE()), (1,5, 'DB5', '2011-09-10', GETDATE()), (1,6, 'DB6', '2013-09-10', GETDATE()), (1,7, 'DB7', '2014-09-10', GETDATE()), (1,8, 'DB8', '2015-09-10', GETDATE()), (1,9, 'DB9', '2016-09-10', GETDATE()), (1,10, 'DB10', '2017-09-10', GETDATE()); --CTE holds all the years starting from the oldest DB ;WITH CTE AS ( SELECT DATEPART(YEAR, ( SELECT MIN(CreateTime) FROM [DB] )) AS year UNION ALL SELECT year + 1 FROM CTE WHERE year < DATEPART(YEAR, GETDATE()) ) SELECT year , COUNT(*) DBCount FROM CTE LEFT JOIN [DB] ON CTE.year BETWEEN DATEPART(YEAR, [DB].Createtime) AND DATEPART(YEAR, [DB].LastCheckTime + 1) WHERE [DB].LastCheckTime > DATEADD(DAY, -1, GETDATE()) -- filter only live DBs GROUP BY year;中，以便能够为我所拥有的问题（大约200左右）提出相同的{{1}}。

Answer 1

据我所知，问题在于View的重点。您可能需要使用OnFocusChangeListener，然后在屏幕处于触摸模式时检查焦点事件是否发生。

或者您可以尝试在每个onClick（视图视图）方法中添加这些行：

view.setFocusableInTouchMode(true);
view.requestFocus();
view.setFocusableInTouchMode(false);

这样，视图将获得焦点，并且在视图再次设置为setFocusableInTouchMode（false）之后，您可以在这些代码行之后在onClick（）方法内部执行某些操作;

单击EditText会导致Button onClick（）函数无效
