这是我的行布局(rowlayout.xml)
<?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">
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/checkedTextView"
android:layout_width="wrap_content"

android:layout_marginLeft="8dp"
android:layout_marginTop="8dp"
android:drawableLeft="?android:attr/listChoiceIndicatorMultiple"

android:text="CheckedTextView" />
<Button

这是我的主要布局(activity_work_condition.xml)

这是我的班级(workconditions.java):
public class WorkConditions extends Activity {
ArrayList<String> selectedItems = new ArrayList<>();
ListView checkablelist;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_work_condition);
checkablelist = findViewById(R.id.checkabalelist);
checkablelist.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
String[] items = {"étudiant",
"chomeur",
"retraité",
"travail à domicile",
"travail au bureau"};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.rowlayout, R.id.checkedTextView, items);
checkablelist.setAdapter(adapter);
CheckedTextView checkedTextView= findViewById(R.id.checkedTextView);
checkablelist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
String selectedItem = ((CheckedTextView) view).getText().toString();
if (selectedItems.contains(selectedItem)) {
selectedItems.remove(selectedItem);
} else selectedItems.add(selectedItem);
}
});
这是结果,
但这些项目无法点击,我无法使用此代码检索数据
String selectedItem = ((CheckedTextView) view).getText().toString();
答案 0 :(得分:0)
在rowlayout.xml中,将 android:descendantFocusability =&#34; blocksDescendants&#34; 添加到根节点(在您的情况下为RelativeLayout)。
rowlayout.xml中的CheckedTextViewview 和按钮都是可聚焦的,这会阻止ListView项获得焦点。
