Question

我正在尝试开发一个使用Camera 2 API的应用程序，但是当我尝试编辑底栏的高度时遇到问题。我想删除相机和底栏之间的黑色空间。此外，我想延长相机的高度。

我关注了Google Camera2Basic示例。

我能解决这个问题吗？

感谢。

        android:paddingRight="16dp"
        android:paddingTop="12dp"
        android:background="@color/white" >

        <ImageButton
            android:id="@+id/picture"
            android:layout_width="@dimen/ic_camera"
            android:layout_height="@dimen/ic_camera"
            android:layout_gravity="center"
            android:background="@drawable/cam_circle_selector"
            android:contentDescription="@string/description_info"
            android:scaleType="fitXY"
            app:srcCompat="@drawable/ic_action_capture" />

    </FrameLayout>

</RelativeLayout>

You can add the Actionbar back which will cause your camera_view getting a little lower and remove the black divider. In styles.xml, replace this line

<style name="MaterialTheme" parent="android:Theme.Material.Light.NoActionBar.Fullscreen" />

with

<style name="MaterialTheme" parent="android:Theme.Material.Light" />

If you don't want to add Actionbar, you may have to modify AutoFitTextureView or Camera2BasicFragment class.
