我想做这样的东西:

如您所见,ViewPager位于顶部,窗口显示在一个ViewPager和一个片段中

我尝试过以下方法:

活动\u homescreen.xml

    private Context context;


    private int[] HomeScreenImages = new int[] {

            android.R.drawable.ic_btn_speak_now,

    public HomeScreenImageAdapter(Context context)
    {
        this.context = context;

    @Override

        return HomeScreenImages.length;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {

       return (view == ((ImageView)object));

    }

    @Override
    public Object instantiateItem (ViewGroup container, int position){

        ImageView imageview = new ImageView(context);

        imageview.setImageResource(HomeScreenImages[position]);

        imageview.setScaleType(ImageView.ScaleType.FIT_CENTER);

        ((ViewPager)container).addView(imageview);

        return imageview;

    }

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


}

但是,我看不到碎片下面的m。仅显示ViewPager。您是否知道我们可以使用Viewpager中的屏幕分割和如上所述的片段?

可能还有其他问题,但首先,为什么不使用LinearLayout作为容器,并使用适当的相等权重

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".HomeScreenActivity"
tools:ignore="MergeRootFrame" >

<android.support.v4.view.ViewPager
    android:id="@+id/home_screen_view_pager"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"/>

<fragment
    android:id="@+id/homescreen_fragment"
    android:layout_width="match_parent"
    android:layout_weight="1"
    android:layout_height="0dp"
    class="com.krupalandharsh.touristguideexperiments.HomeScreenFragment" />

</LinearLayout>

我对您主页上的xml感到困惑:“活动\主屏幕”。 您对父布局使用相对布局,但也为两个子布局添加了参数“权重”,其中一个子布局使用0dp宽度。 是否要使用“权重”为viewPager和片段分配空间

我添加和更改了一些代码,并在下面显示。我将父布局更改为LinearLayout并添加“weightSum”。 对于子布局,我为高度指定0dp,为宽度指定与父布局匹配的宽度,并为权重指定高度。您可以更改参数以适合您的设计

我没有尝试过,所以我不确定它是否会起作用。你可以试试

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

    android:id="@+id/container"

    android:layout_width="match_parent"
    android:layout_height="match_parent"

    tools:context=".HomeScreenActivity" tools:ignore="MergeRootFrame"

    android:weightSum="6"

    >
    <android.support.v4.view.ViewPager
        android:id="@+id/home_screen_view_pager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="5"/>

    <fragment
        android:id="@+id/homescreen_fragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        class="com.krupalandharsh.touristguideexperiments.HomeScreenFragment" />

</LinearLayout>
