我遇到了 ListView 的问题，它在 ListView 中只显示一行。我认为问题出在布局行 xml 中，但我不知道问题出在哪里。感谢您的帮助，我将不胜感激。
这是我的 row.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:background="@drawable/fondgris"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/linearLayout2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:id="@+id/imageTypeWorkitem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:paddingTop="10dp"
android:src="@drawable/bugicon" />
<TextView
android:id="@+id/typeWorkitem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:paddingTop="10dp"
android:textSize="14sp"
android:textStyle="bold" />
<ImageView
android:id="@+id/imagePriority"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:paddingTop="10dp"
android:src="@drawable/priorityhigh" />
<TextView
android:id="@+id/priority"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:paddingTop="10dp"
android:textSize="14sp"
android:textStyle="bold" />
<TextView
android:id="@+id/key"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:paddingTop="10dp"
android:textSize="14sp"
android:textStyle="bold" />
</LinearLayout>
<LinearLayout
android:id="@+id/linearLayout3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:id="@+id/imageStatus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:paddingTop="10dp"
android:src="@drawable/statusopen" />
<TextView
android:id="@+id/status"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/priority"
android:layout_marginLeft="10dp"
android:paddingTop="10dp"
android:textSize="14sp"
android:textStyle="bold" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
这是我的适配器：
import java.util.List;
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import com.client.alm.model.WorkItem;
import com.client.alm.model.WorkItemContainer;
public class WorkItemAdapter extends ArrayAdapter<WorkItem> {
private WorkItemContainer container;
private Context context;
int layoutResourceId;
public WorkItemAdapter(Context context, int layoutResourceId,
WorkItemContainer container) {
super(context, layoutResourceId, container.getWorkitems());
this.layoutResourceId = layoutResourceId;
this.context = context;
this.container = container;
}
static class ViewHolder {
ImageView imageType;
TextView type;
TextView priority;
ImageView imagePriority;
TextView key;
ImageView imageStatus;
TextView status;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
ViewHolder holder = null;
if (row == null) {
LayoutInflater inflater = LayoutInflater.from(context);
row = inflater.inflate(layoutResourceId, parent, false);
holder = new ViewHolder();
holder.imageType = (ImageView) row
.findViewById(R.id.imageTypeWorkitem);
holder.type = (TextView) row.findViewById(R.id.typeWorkitem);
holder.imagePriority = (ImageView) row
.findViewById(R.id.imagePriority);
holder.priority=(TextView) row.findViewById(R.id.priority);
holder.key = (TextView) row.findViewById(R.id.key);
holder.imageStatus = (ImageView) row.findViewById(R.id.imageStatus);
holder.status = (TextView) row.findViewById(R.id.status);
row.setTag(holder);
} else {
holder = (ViewHolder) row.getTag();
}
WorkItem workitem = container.getWorkitems().get(position);
holder.type.setText(workitem.getType());
// holder.imageType.setImageResource(workitem.getIcon());
holder.priority.setText(workitem.getPriority());
holder.key.setText(workitem.getKey());
holder.status.setText(workitem.getStatus());
return row;
}
}
这是我加载列表的代码：
WorkItemContainer container = gson.fromJson(resultat,
WorkItemContainer.class);
/**
* Updating parsed JSON data into ListView
* */
WorkItemAdapter adaptateur = new WorkItemAdapter(
WorkItemActivity.this, R.layout.ligne_workitem, container);
setListAdapter(adaptateur);
