Android 视图寻呼机和gridview可以一起滚动

我的布局中有ViewPager和grid视图。目前只有grid视图在page ViewPager下方滚动。如何使这两个视图都可以垂直滚动？我使用了嵌套滚动，但没有任何效果..请指导我

布局：

<?xml version="1.0" encoding="utf-8"?>
 <LinearLayout android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
tools:context=".MainActivity"
xmlns:android="http://schemas.android.com/apk/res/android">
 <androidx.viewpager.widget.ViewPager
    android:layout_width="match_parent"
    android:layout_height="140dp"
    android:id="@+id/viewpagermain"
    android:layout_gravity="center_horizontal">

  </androidx.viewpager.widget.ViewPager>

<LinearLayout
    android:id="@+id/SliderDots"
    android:layout_below="@+id/viewPager"
    android:orientation="horizontal"
    android:gravity="center_vertical|center_horizontal"
    android:layout_width="match_parent"
    android:layout_height="15dp"/>
 <GridView
  android:id="@+id/mGridView"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:paddingTop="5dp"
  android:paddingLeft="5dp"
  android:paddingRight="5dp"
  android:numColumns="auto_fit"
  android:columnWidth="172dp"
  android:horizontalSpacing="5dp"
  android:verticalSpacing="5dp"
  android:gravity="center"
  android:stretchMode="columnWidth"
  android:background="#ffffff">
</GridView>
</LinearLayout>

以上代码工作：

两者单独运行都很好…但我只能滚动gridview项目，在ViewPager保持其位置的地方垂直滚动（不向上）。我需要nestedscrollview中的帮助，但没有任何效果，请帮助我。

要将页面和网格一起垂直滚动，您可以使用

recyclerview

而不是

gridview

：

在XML和java文件中尝试以下代码： XML文件：

<?xml version="1.0" encoding="utf-8"?>
<androidx.core.widget.NestedScrollView 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"
    tools:context=".ViewPagerActivity">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
        <androidx.viewpager.widget.ViewPager
            android:layout_width="match_parent"
            android:layout_height="140dp"
            android:id="@+id/viewpagermain"
            android:layout_gravity="center_horizontal">

        </androidx.viewpager.widget.ViewPager>

        <LinearLayout
            android:id="@+id/SliderDots"
            android:layout_below="@+id/viewPager"
            android:orientation="horizontal"
            android:gravity="center_vertical|center_horizontal"
            android:layout_width="match_parent"
            android:layout_height="15dp"/>
        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:paddingTop="5dp"
            android:paddingLeft="5dp"
            android:paddingRight="5dp"
            android:numColumns="auto_fit"
            android:columnWidth="172dp"
            android:horizontalSpacing="5dp"
            android:verticalSpacing="5dp"
            android:gravity="center"
            android:stretchMode="columnWidth"
            android:background="#ffffff">
        </androidx.recyclerview.widget.RecyclerView>
    </LinearLayout>
</androidx.core.widget.NestedScrollView>

我希望它在您的main活动中对您有效。java类方法

onCreate

编写代码：

GridView gridView = (GridView) findViewById(R.id.grid_view);
// Instance of ImageAdapter Class
gridView.setAdapter(new ImageAdapter(this));
// Instantiate a ViewPager and a PagerAdapter.
mPager = (ViewPager) findViewById(R.id.pager);
// Create ScreenSlidePagerAdapter class and then implement viewPager.
pagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager());
mPager.setAdapter(pagerAdapter);

在

activity\u main.xml

文件中实现这一点

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity4">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:focusableInTouchMode="true"
        android:orientation="vertical">
        <android.support.v4.view.ViewPager
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/pager"
            android:layout_width="match_parent"
            android:layout_height="140sp"
            android:layout_marginBottom="10dp"
            android:layout_gravity="center_horizontal"/>
        <com.xx.xxx.MyGridView
            android:id="@+id/grid_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:numColumns="auto_fit"
            android:columnWidth="90dp"
            android:horizontalSpacing="10dp"
            android:verticalSpacing="10dp"
            android:gravity="center"
            android:stretchMode="columnWidth"
            android:layout_marginBottom="10dp"/>
    </LinearLayout>
</ScrollView>

编辑：

根据我的代码myImageAdapter.java类：

public class ImageAdapter extends BaseAdapter {
    private Context mContext;

    // Keep all Images in array
    public Integer[] mThumbIds = {
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download, R.drawable.download,
            R.drawable.download
    };

    // Constructor
    public ImageAdapter(Context c){
        mContext = c;
    }

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

    @Override
    public Object getItem(int position) {
        return mThumbIds[position];
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView = new ImageView(mContext);
        imageView.setImageResource(mThumbIds[position]);
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setLayoutParams(new GridView.LayoutParams(70, 70));
        return imageView;
    }

}

我希望它能帮助你。。。！继续编码

请提供一个屏幕截图。我添加了ss有一个look单张图片也有一个水平滚动视图，GridView有一个垂直滚动视图。我是对的！请查看我的代码，希望它对您有帮助，如果您有任何问题，请问我。您找到答案了吗？或者需要帮助吗？嘿..实际上我的gridview适配器扩展了baseadapter..我正在baseadapter的getView（）下获取数据..当我扩展gridview时，我应该如何获取数据？

public class MyGridView extends GridView {
    public MyGridView(Context context) {
        super(context);
    }

    public MyGridView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyGridView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int heightSpec;

        if (getLayoutParams().height == LayoutParams.MATCH_PARENT) {
            // The great Android "hackatlon", the love, the magic.
            // The two leftmost bits in the height measure spec have
            // a special meaning, hence we can't use them to describe height.
            heightSpec = MeasureSpec.makeMeasureSpec(
                    Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        }
        else {
            // Any other height should be respected as is.
            heightSpec = heightMeasureSpec;
        }

        super.onMeasure(widthMeasureSpec, heightSpec);
    }
}

public class ImageAdapter extends BaseAdapter {
    private Context mContext;

    // Keep all Images in array
    public Integer[] mThumbIds = {
