私のアプリケーションでは、いくつかの5つのギャラリービューを使用して画像を表示していますが、正しく行われているため、画像を正しく入力できます.今、各画像の下にテキストビューを追加したいと思います.

次のようなギャラリー ビューが必要です。

image1    Image2    Image3  image4
                                             -------->Galleryview1

text1     text2      text3   text4

------------------------------------------
image1    image2    image3    image4

                                             --------->Galleryview2
text1     text2      text3    text4

私のコード:

アダプターコード:

xmlコードの代わりに以下のxmlコードを使用すると、問題が解決します。それに関して問題がある場合は、教えてください。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

        <ImageView
            android:id="@+id/imageview1"
            android:layout_width="120dp"
            android:layout_height="100dp"
            android:layout_marginLeft="10dp"
            android:layout_marginTop="-20dp"
            android:paddingLeft="10dp"
            android:paddingRight="10dp" 
            android:src="@drawable/ic_launcher"/>

        <TextView
            android:id="@+id/Txt01"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
