In Android, how does one set static data for ListView? androidlistview

Sometimes we need to set fixed data for a listview. below is how to set static data

Layout file listview Homepage

<?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="@+id/listview"        android:layout_width="fill_parent"        android:layout_height="fill_parent" >    </ListView></LinearLayout>

Then a layout file is the item of each listview, and listview_item.xml contains images and text

<?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="horizontal" >    <ImageView        android:id="@+id/listitem_iv"        android:layout_width="74dp"        android:layout_height="74dp"        android:src="@drawable/about_brand" />    <TextView        android:id="@+id/listitem_tv"        android:layout_width="match_parent"        android:layout_height="74dp"        android:text="TextView"        android:textAlignment="center"        android:textSize="55dp" /></LinearLayout>

Then the key is how to set static data:
ListViewUseAdapter. java

Import java. util. arrayList; import java. util. hashMap; import java. util. list; import java. util. map; import android. app. activity; import android. OS. bundle; import android. view. view; import android. widget. adapterView; import android. widget. toast; import android. widget. adapterView. onItemClickListener; import android. widget. listView; public class ListViewUseAdapter extends Activity {private ListView listview; @ Ov Erride protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. listview_test); listview = (ListView) this. findViewById (R. id. listview); // set the image resource int [] imageId = new int [] {R. drawable. chat_tool_camera, R. drawable. chat_tool_location, R. drawable. chat_tool_paint, R. drawable. chat_tool_video, R. drawable. chat_tool_voice, R. drawable. about_brand }; // Set the title String [] title = new String [] {"camera", "positioning", "paint brush", "video", "sound ", "chat" }; List <Map <String, Object> listitem = new ArrayList <Map <String, Object> (); // convert the above resources into a list set for (int I = 0; I <title. length; I ++) {Map <String, Object> map = new HashMap <String, Object> (); map. put ("image", imageId [I]); map. put ("title", title [I]); listitem. add (map);} ListViewAdapter adapter = new ListViewAdapter (th Is, listitem); listview. setAdapter (adapter); listview. setOnItemClickListener (new OnItemClickListener () {@ Override public void onItemClick (AdapterView <?> Parent, View view, int position, long id) {Toast. makeText (ListViewUseAdapter. this, "haha", Toast. LENGTH_SHORT). show ();}});}}

The required adapter is as follows:

import java.util.List;import java.util.Map;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.TextView;public class ListViewAdapter extends BaseAdapter {    private Context context;    private List<Map<String, Object>> listitem;    public ListViewAdapter(Context context, List<Map<String, Object>> listitem) {        this.context = context;        this.listitem = listitem;    }    @Override    public int getCount() {        return listitem.size();    }    @Override    public Object getItem(int position) {        return listitem.get(position);    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        if (convertView == null) {            convertView = LayoutInflater.from(context).inflate(R.layout.listview_item, null);        }        ImageView imageView = (ImageView) convertView.findViewById(R.id.listitem_iv);        TextView textView = (TextView) convertView.findViewById(R.id.listitem_tv);        Map<String, Object> map = listitem.get(position);        imageView.setImageResource((Integer) map.get("image"));        textView.setText(map.get("title") + "");        return convertView;    }}

The effect is as follows:
