点击它时我有一个按钮,显示带有listview
的片段。
stateFragment = new StateFragment();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.relativLaout_Sates, stateFragment, "StatFag").commit();
这是onCreateview()
StateFragment
listView = (ListView) view.findViewById(R.id.list);
adapter = new ArrayAdapter<String>(getActivity(), R.layout.row_layout, R.id.row1, items);
listView.setAdapter(adapter);
listView.setSelectionFromTop(getpos, getoffset);
listView.setOnItemClickListener(StateFragment.this);
以及listview的布局代码:
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@null"
android:dividerHeight="4dp"
android:choiceMode="singleChoice"
/>
和行:
<TextView
android:text="TextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:textSize="@dimen/textSiz_home_page"
android:id="@+id/row1"
android:gravity="center"
android:background="@drawable/bg_txt_add_it"
android:layout_alignParentEnd="true"
style="@style/MyTextTheme"/>
,bg_txt_add_it的代码是:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape>
<corners android:radius="8dp"/>
<solid android:color="@color/blue" />
</shape>
</item>
<item android:drawable="@color/blue2" android:state_activated="true"/>
并在onItemClick中代码为:
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
view.getFocusables(getpos);
view.setSelected(true);
当我再次打开此ListView
时,它会滚动到之前选择的项目但是高亮度选择在两秒后消失,是否有任何建议?
