如何在StaggeredGridView活動中添加工具欄

Question

我正在使用StaggeredGridView，我想在StaggeredGridView中添加工具欄，這是我的活動：

public class CategoryCarActivity extends AppCompatActivity implements AbsListView.OnScrollListener, AbsListView.OnItemClickListener {

   @Override
   protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sgv);

    Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);

    setSupportActionBar(toolbar);
    // getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    ...
}

activity_sgv.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<com.etsy.android.grid.StaggeredGridView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/grid_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:item_margin="8dp"
app:column_count="@integer/grid_column_count" />

<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:titleTextColor="@android:color/holo_blue_bright" />

<TextView
android:id="@+id/text_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="@dimen/activity_horizontal_margin"
android:gravity="center" />
</LinearLayout>

通過檢查Logcat不會顯示工具欄，並且沒有發生任何錯誤。

如何解決此問題到Toobar顯示？ 謝謝 ！

您無法看到ToolBar包裹在StaggeredGridView下面。

怎么修：

嘗試這個：

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:titleTextColor="@android:color/holo_blue_bright" />

<com.etsy.android.grid.StaggeredGridView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/grid_view"
android:layout_below="@id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:item_margin="8dp"
app:column_count="@integer/grid_column_count" />



<TextView
android:id="@+id/text_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="@dimen/activity_horizontal_margin"
android:gravity="center" />
