您应该做的是以下内容：可扩展高度gridview：这意味着您向GridView添加的项目越多，它就会扩展得越多。（这是你需要的）。

现在该怎么做很简单：

首先，您需要创建一个java类：

public class ExpandableHeightGridView extends GridView {

boolean expanded = false;

public ExpandableHeightGridView(Context context)
{
    super(context);
}

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

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

public boolean isExpanded()
{
    return expanded;
}

@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
    // This is a definite hack!!
    if (isExpanded())
    {
        // Calculate entire height by providing a very large height hint.
        // View.MEASURED_SIZE_MASK represents the largest height possible.
        int expandSpec = View.MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK,
                View.MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);

        ViewGroup.LayoutParams params = getLayoutParams();
        params.height = getMeasuredHeight();
    }
    else
    {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}

public void setExpanded(boolean expanded)
{
    this.expanded = expanded;
} }

然后在xml布局中：

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

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">





    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">


        <ImageView 
            android:id="@+id/image"
            android:layout_width="match_parent"
        android:layout_height="100sp"
        android:src="@drawable/ic_launcher" 

            />


 <custom.ExpandableHeightGridView
                    android:id="@+id/grid1"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_marginBottom="15dp"
                    android:layout_marginTop="5dp"
                    android:horizontalSpacing="10dp"
                    android:isScrollContainer="false"
                    android:numColumns="3"
                    android:stretchMode="columnWidth"
                    android:verticalSpacing="10dp" />


    <TextView 
         android:id="@+id/text"
         android:layout_below="@+id/gridview"
       android:layout_width="match_parent"
    android:layout_height="wrap_content"   
    android:text="Treding"
         />



         <custom.ExpandableHeightGridView
                    android:id="@+id/grid"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_marginBottom="15dp"
                    android:layout_marginTop="5dp"
                    android:horizontalSpacing="10dp"
                    android:isScrollContainer="false"
                    android:numColumns="3"
                    android:stretchMode="columnWidth"
                    android:verticalSpacing="10dp" />
    </RelativeLayout>
</ScrollView>

然后在你的活动中：

grid = (ExpandableHeightGridView) findViewById(R.id.grid);
    grid.setExpanded(true);
grid.setAdapter(your adapter);
