我想要两个在列表视图的每一行中显示两个图像和两个文本视图。我已经尝试过了，但没有显示图像。
这是自定义列表视图源代码，custom_listview.xml：
<?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="wrap_content" >
<RelativeLayout
android:id="@+id/custom_ListView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:gravity="center"
android:padding="20dp" >
<ImageView
android:id="@+id/imgBook1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="30dp"
android:src="@drawable/book1" />
<TextView
android:id="@+id/txtTitleBook1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/imgBook1"
android:text="Book1 Title Here" />
<ImageView
android:id="@+id/imgBook2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="30dp"
android:layout_toRightOf="@+id/imgBook1"
android:src="@drawable/book2" />
<TextView
android:id="@+id/txtTitleBook2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="@+id/txtTitleBook1"
android:layout_alignBottom="@+id/txtTitleBook2"
android:layout_toRightOf="@+id/txtTitleBook1"
android:text="Book2 Title Here" />
</RelativeLayout>
</RelativeLayout>
这是main.xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
这是我的Java代码Main.java：
package my.islamic.books.lib.app;
import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class Home extends ListActivity {
String[] booksTitles = { "Book1", "Book2", "Book3", "Book4" };
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.home_activity);
setListAdapter(new MyAdapter(this, android.R.id.text1, booksTitles));
}
private class MyAdapter extends ArrayAdapter<String> {
int[] booksCoverPhotos = { R.id.imgBook1, R.id.imgBook2, R.id.imgBook1,
R.id.imgBook2};
public MyAdapter(Context context, int resource, String[] objects) {
// super(context, resource, textViewResourceId, objects);
super(context, resource, objects);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = inflater.inflate(R.layout.listview_body, parent, false);
ImageView imgView_book1 = (ImageView) row
.findViewById(R.id.imgBook1);
ImageView imgView_book2 = (ImageView) row
.findViewById(R.id.imgBook2);
TextView txtView_bookTitle1 = (TextView) row
.findViewById(R.id.txtTitleBook1);
TextView txtView_bookTitle2 = (TextView) row
.findViewById(R.id.txtTitleBook2);
txtView_bookTitle1.setText(booksTitles[position]);
imgView_book1.setImageResource(booksCoverPhotos[position]);
imgView_book2.setImageResource(booksCoverPhotos[position]);
txtView_bookTitle2.setText(booksTitles[position]);
return row;
}
}// end class
}
而且，当我在上面的 Java 代码中对任何 imgView_book1 或 imgView_book2 进行评论时，它会在 listView 的每一行中显示一个图像，但为什么不是两个图像呢？
