在我的应用程序中,我试图从 Web 服务中获取一组用户的详细信息。然后,我想在 GridLayout 中显示每个用户的图像及其名称。我以前没有使用过 GridLayout,因此尝试浏览在线可用的教程,但其中大多数只处理图像。我需要在网格中显示图像和文本。
如何设置自定义 GridLayout 以显示 Text 和 Images ?

如何设置自定义 GridLayout 以显示 Text 和 Images ?
试试这个 :
public class GridActivity extends Activity implements AdapterView.OnItemClickListener {
/** Called when the activity is first created. */
Integer[] imageIDs = {
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
R.drawable.ic_launcher,
};
String[] titles = {
"First",
"Second",
"Third",
"Fourth",
"Fifth",
"First",
"Second",
"Third",
"Fourth",
"Fifth",
"First",
"Second",
"Third",
"Fourth",
"Fifth",
"First",
"Second",
"Third",
"Fourth",
"Fifth",
"First",
"Second",
"Third",
"Fourth",
"Fifth",
"First",
"Second",
"Third",
"Fourth",
"Fifth",
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
GridView gridView = (GridView) findViewById(R.id.grid);
gridView.setAdapter(new ImageAdapter(this));
}
public class ImageAdapter extends BaseAdapter
{
private Context context;
public ImageAdapter(Context c)
{
context = c;
}
//---returns the number of images---
public int getCount() {
return imageIDs.length;
}
//---returns the ID of an item---
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
//---returns an ImageView view---
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView icon;
icon = new ImageView(context);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row=inflater.inflate(R.layout.row, parent, false);
TextView label=(TextView)row.findViewById(R.id.image_name);
label.setText(titles[position]);
icon=(ImageView)row.findViewById(R.id.album_image);
icon.setImageResource(imageIDs[position]);
return row;
}
}
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
}
}
主文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<GridView
android:id="@+id/grid"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="@+id/lay"
android:columnWidth="100px"
android:horizontalSpacing="5dip"
android:numColumns="auto_fit"
android:scrollbars="horizontal"
android:stretchMode="columnWidth"
android:verticalSpacing="35px" />
</LinearLayout>
行.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id = "@+id/album_image"
android:adjustViewBounds="true"
android:layout_width = "fill_parent"
android:layout_height="wrap_content"
/>
<TextView
android:id = "@+id/image_name"
android:layout_width = "fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
/>
</LinearLayout>
这是带有 ImageView 和 TextView 的 GridView 的一个非常好的示例。
只需像这样使用 ImageView 和 textView 创建一个 xml 文件,
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/widget44"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_x="201px"
android:layout_y="165px"
android:gravity="center_horizontal">
<ImageView
android:id="@+id/icon_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</ImageView>
<TextView
android:id="@+id/icon_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
android:gravity="center_horizontal"
android:textColorHighlight="#656565">
</TextView>
</LinearLayout>
然后使用自定义适配器填充它。
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v;
if(convertView==null){
LayoutInflater li = getLayoutInflater();
v = li.inflate(R.layout.icon, null);
TextView tv = (TextView)v.findViewById(R.id.icon_text);
tv.setText("Profile "+position);
ImageView iv = (ImageView)v.findViewById(R.id.icon_image);
iv.setImageResource(R.drawable.icon);
}
else
{
v = convertView;
}
return v;
}
