Listview可见/消失的项目显示问题

标签: listview display visible

我正在使用listview和其他视图(tablayout和viewpager)创建一个布局。

我将列表视图设置为“消失”,其他视图可见。

当我将listview更改为VISIBLE并将其他更改为GONE时,Listview不显示任何内容。

可能是什么原因造成的?

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <android.support.design.widget.TabLayout
        android:id="@+id/tab_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="fill"
        app:tabMode="scrollable"
        app:tabTextColor="@color/colorPrimary"
        app:tabIndicatorColor="@color/colorPrimaryDark"
        app:tabSelectedTextColor="@color/colorPrimaryDark" />

    <android.support.v4.view.ViewPager
        android:id="@+id/tab_view_page"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <include layout="@layout/search_listview_main"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:visibility="gone"/>
</LinearLayout>

这是我的代码:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.app_bar_menu_mrecords, menu);

    searchView_mrecords = (SearchView) menu.findItem(R.id.bt_search_mrecords).getActionView();
    searchView_mrecords.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            adapter_search_patient_info.getFilter().filter(newText);
            return false;
        }
    });

    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        //when click button search , show listview and visible other view 
        case R.id.bt_search_mrecords:
            tabLayout_patient_info.setVisibility(View.GONE);
            viewPager_patient_info.setVisibility(View.GONE);
            listView_search_patients.setVisibility(View.VISIBLE);
            return true;
    }
    return super.onOptionsItemSelected(item);
}
