Question

我已经使用View Pager通过以下教程创建了一个图像滑块所以我的问题是我希望我的滑块有一个透明的工具栏当我点击屏幕时，工具栏将隐藏这是我的代码和输出（我做的），以及我想要的输出。

我的活动

public class viewInfo extends AppCompatActivity{
private ViewPager viewPager;
private Toolbar toolbar;
private CustomSwipeAdapter adapter;
PhotoViewAttacher mAttacher;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_view_info);
    toolbar = (Toolbar) findViewById(R.id.app_bar);
    setSupportActionBar(toolbar);
    viewPager = (ViewPager) findViewById(R.id.view_pager);
    adapter = new CustomSwipeAdapter(this);
    viewPager.setAdapter(adapter);


}


public class CustomSwipeAdapter extends PagerAdapter {
    private int[] image_resources = {R.drawable.bsu, R.drawable.gameover2};
    private Context context;
    private LayoutInflater layoutInflater;

    public CustomSwipeAdapter(Context context) {
        this.context = context;
    }

    @Override
    public int getCount() {
        return image_resources.length;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return (view == (LinearLayout) object);
    }

    @Override
    public Object instantiateItem(View container, int position) {
        layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View item_view = layoutInflater.inflate(R.layout.swipe_layout, (ViewGroup) container, false);
        ImageView imageView = (ImageView) item_view.findViewById(R.id.image_view);
        imageView.setPadding(5, 5, 5, 5);
        imageView.setImageResource(image_resources[position]);
        ((ViewGroup) container).addView(item_view);

        mAttacher = new PhotoViewAttacher(imageView);
        mAttacher.update();
        return item_view;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((LinearLayout) object);
    }
}

}

2.XML（swipe_layout）

 <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:gravity="center"
    android:background="#000"
    >
    <ImageView
        android:id="@+id/image_view"
        android:layout_width="match_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="center"
        android:gravity="center"
        />
</LinearLayout>

3.XML（我的活动的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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FFF"
    android:orientation="vertical"
    tools:context="com.thesis.juandirection.juandirectionfinale.viewInfos.viewInfo">


    <include
        android:id="@id/app_bar"
        layout="@layout/app_bar" />

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

    </android.support.v4.view.ViewPager>

</LinearLayout>

我想要的是这种效果..
透明工具栏。
当用户
试图将侦听器放到Linearlayout时点击它将隐藏工具栏的布局，但没有运气。

图像滑块使用视图寻呼机（使用透明工具栏）
