我已经为 gridview 编写了代码，我可以在其中显示图像和文本，但我想在单个可滚动行中显示所有图像，例如 Pulse 新闻应用程序。我已经在 xml 中为 gridview 实现了水平滚动视图，但它根本不起作用。我正在将 pageviwer 用于选项卡，并且正在使用片段。
这是我的xml代码
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<HorizontalScrollView
android:id="@+id/horizontalScrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:scrollbars="horizontal" >
<GridView
android:layout_width="500dp"
android:layout_height="400dp"
android:id="@+id/gridview"
android:columnWidth="300dp"
android:numColumns="3"
android:horizontalSpacing="10dp"
android:scrollbars="horizontal">
</GridView>
</HorizontalScrollView>
</RelativeLayout>
这是我的图像适配器代码
public class ImageAdapter extends BaseAdapter {
private Context context;
private final String[] mobileValues;
private TextView t;
public ImageAdapter(Context context, String[] mobileValues) {
this.context = context;
this.mobileValues = mobileValues;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
if (convertView == null) {
gridView = new View(context);
// get layout from mobile.xml
gridView = inflater.inflate(R.layout.showlist_item, null);
// set value into textview
TextView textView = (TextView) gridView
.findViewById(R.id.grid_item_label);
textView.setText(mobileValues[position]);
// set image based on selected text
ImageView imageView = (ImageView) gridView
.findViewById(R.id.grid_item_image);
String mobile = mobileValues[position];
if (mobile.equals("Windows")) {
imageView.setImageResource(R.drawable.test_play_image);
} else if (mobile.equals("iOS")) {
imageView.setImageResource(R.drawable.test_play_image);
} else if (mobile.equals("Blackberry")) {
imageView.setImageResource(R.drawable.test_play_image);
} else {
imageView.setImageResource(R.drawable.test_play_image);
}
} else {
gridView = (View) convertView;
}
return gridView;
}
private void clickedButton(TextView tv){
int num = Integer.parseInt(tv.getText().toString());
++num;
tv.setText(Integer.toString(num));
}
private void clickedButtonm(TextView tv){
int num = Integer.parseInt(tv.getText().toString());
if(num>0){
--num;
tv.setText(Integer.toString(num));
}
}
public int getCount() {
return mobileValues.length;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
class MyOnClickListener implements OnClickListener{
public final TextView tv;
public MyOnClickListener(TextView tv){
this.tv=tv;
}
public void onClick(View v) {
// TODO Auto-generated method stub
clickedButton(tv);
}
}
class MyOnClickListenerm implements OnClickListener{
public final TextView tv;
public MyOnClickListenerm(TextView tv){
this.tv=tv;
}
public void onClick(View v) {
// TODO Auto-generated method stub
clickedButtonm(tv);
}
}
我想像这样向右滚动显示。
