如何插入更改ListView的图形,将此布局文件添加到列表视图中?我应该在我的java代码中写一下我的ListView的每一行就像我的布局文件一样。谢谢大家!!

首先,您需要为所需的自定义行创建xml(custom_row.xml):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="8dp"
android:id="@+id/text" /> </LinearLayout>
然后您需要创建自定义适配器:
public class CustomAdapter extends BaseAdapter {
Context context;
List<String> textArray;
LayoutInflater inflater;
public RutinaAdapter(Context context, List<String> textarray) {
this.context = context;
inflater = LayoutInflater.from(context);
this.textArray = textarray;
}
@Override
public int getCount() {
return textArray.size();
}
@Override
public Object getItem(int position) {
return textArray.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewGroup vg;
if (convertView != null) {
vg = (ViewGroup) convertView;
} else {
vg = (ViewGroup) inflater.inflate(R.layout.custom_row, null);
}
String text = textArray.get(position);
final TextView text = ((TextView) vg.findViewById(R.id.text));
return vg;
} }
然后您需要将适配器添加到ListView:
list = (ListView) view.findViewById(R.id.list);
CustomAdapter adapter = new CustomAdapter(getContext(),textArray);
list.setAdapter(adapter1);
向textArray添加信息,并通知适配器数据已更改,就是这样。
