Android GridView具有不同的行号

Question

I need to use a gridview and I want to change row numbers dynamically.

Example:

I need something like this:

I receive an ArrayList with the result, I need to show first ten results on single row and results from eleven to end on two rows layout.

is it possible to do?

Answer 1

To accomplish this , you can use listview with custom adapter, you need to create 2 custom listview item with one column, and second one with 2 column.

then use

getViewTypeCount()

which will return 2 in your case.

and in getView() check the type with

getItemViewType(int position)

and create the appropriate view and return it.

Answer 2

对于前10个项目，您可以使用两个不同的网格视图（单行），对于11个结束项目，可以使用第二个（有两行）。

Answer 3

I would create two layouts, both being GridView , one with one column and the other with two columns. I would suggest using a ListView for the first as it is only one column but you cannot put an unscrollable ListView inside a ScrollView . I see you said you've tried this but it doesn't look very nice as they scroll separately.

Try adding a ScrollView around both GridView s and then disable the scrollability of the items inside and then it should scroll as one item.

Here is the code for the ScrollView:

<ScrollView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">

and then obviously end it at the end of your XML with this:

</ScrollView>

After doing that, you should then disable the scrollability of both the GridView s using this line:

gridView.setScrollContainer(false);

I hope this helps! Ask if you need anything.

This is my layout code.

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/ScrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".Listado" >

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ListView
            android:id="@+id/lvDestacadas"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="3dp"
            tools:listitem="@layout/celda" >
        </ListView>

        <GridView
            android:id="@+id/gvGeneral"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:horizontalSpacing="2dip"
            android:numColumns="2"
            android:verticalSpacing="2dip"
            tools:listitem="@layout/celda_grid" >
        </GridView>
</LinearLayout>

Answer 5

If it always needs to be done this way ie always first 10 will be in a single row then you can do it with custom adapter. Override getView, you get position as arguement return the view as required.
