actually I've read some previous questions about this...
this is the code that I use
auto = (ListView)findViewById(R.id.auto);
String[] projection = new String[] {Browser.BookmarkColumns._ID,Browser.BookmarkColumns.TITLE,Browser.BookmarkColumns.URL};
String[] displayFields = new String[] {Browser.BookmarkColumns.TITLE, Browser.BookmarkColumns.URL};
int[] displayViews = new int[] { R.id.text1,R.id.text2 };
Cursor cur = managedQuery(android.provider.Browser.BOOKMARKS_URI,projection, null, null, null);
//auto.setAdapter(new SimpleCursorAdapter(this, R.layout.mylist, cur,displayFields, displayViews));
myAdapter apt = new myAdapter(this, R.layout.mylist, cur,displayFields, displayViews);
auto.setAdapter(apt);
and class myAdapter
class myAdapter extends SimpleCursorAdapter{
private Cursor c;
private Context context;
public myAdapter(Context context, int layout, Cursor c, String[] from,
int[] to) {
super(context, layout, c, from, to);
// TODO Auto-generated constructor stub
this.c = c;
this.context = context;
AutoList att = new AutoList();
mListView = att.auto;
}
@Override
public View getView(int pos, View inView, ViewGroup parent) {
View vix = inView;
if (vix == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
vix = inflater.inflate(R.layout.mylist, null);
}
this.c.moveToPosition(pos);
String title = this.c.getString(this.c.getColumnIndex(Browser.BookmarkColumns.TITLE));
String cont = this.c.getString(this.c.getColumnIndex(Browser.BookmarkColumns.URL));
TextView text1 = (TextView) vix.findViewById(R.id.text1);
text1.setText(title);
TextView text2 = (TextView) vix.findViewById(R.id.text2);
text2.setText(cont);
Button butt = (Button) vix.findViewById(R.id.button);
butt.setOnClickListener(mButt);
return vix;
}
private OnClickListener mButt = new OnClickListener() {
@Override
public void onClick(View v) {
final int position = mListView.getPositionForView((View) v.getParent());
Log.v("BUTT", "Title clicked, row "+position);
}
};
However, when I click the button, I still get a lot of errors like this:
04-10 22:30:55.152: ERROR/AndroidRuntime(695): FATAL EXCEPTION: main

That's it! I hope it won't be so difficult to be figured out!
Thanks!
ListView with Clickable Buttons!!!
Well...., here's the rough method to solve my problem SO FAR....
item.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:orientation="horizontal"
android:layout_height="wrap_content">
<TextView android:id="@+id/showTv"
android:layout_alignParentLeft="true"
android:gravity="center_vertical"
android:textSize="24dip"
android:layout_height="wrap_content"
android:layout_width="wrap_content" />
<RelativeLayout android:id="@+id/jjjj"
android:layout_alignParentRight="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
<Button android:id="@+id/gointoBt"
android:focusable="false"
android:layout_alignParentRight="true"
android:text="abc"
android:layout_height="wrap_content"
android:layout_width="wrap_content"/>
<Button android:id="@+id/chooseBt"
android:layout_toLeftOf="@id/gointoBt"
android:layout_marginRight="10dip"
android:text="text"
android:focusable="false"
android:layout_height="wrap_content"
android:layout_width="wrap_content"/>
</RelativeLayout>
MySimpleAdapter：
import ........;
public class MySimpleAdapter extends SimpleAdapter {
private final Context context;
private List<Map<String, Object>> data;
private int resource;
private String[] from;
private int[] to;
public MySimpleAdapter(Context context,List<? extends Map<String, ?>> data, int resource, String[] from,
int[] to) {
super(context, data, resource, from, to);
this.context=context;
this.data=(List<Map<String, Object>>) data;
this.resource=resource;
this.from=from;
this.to=to;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
View rowView = inflater.inflate(resource, null, true);
Map<String, Object> medMap=data.get(position);
final TextView[] showTv=new TextView[from.length];
for (int i = 0; i < from.length; i++) {
showTv[i]=(TextView)rowView.findViewById(to[i]);
showTv[i].setText(""+medMap.get(from[i]));
}
Button btn=(Button)rowView.findViewById(R.id.gointoBt);
Button.OnClickListener mOkOnClickListener = new Button.OnClickListener()
{
public void onClick(View v) {
Log.v("ttttttt", ""+showTv[0].getText());
Toast.makeText(context,""+showTv[0].getText(), Toast.LENGTH_LONG).show();
}
};
btn.setOnClickListener(mOkOnClickListener);
Button btn2=(Button)rowView.findViewById(R.id.chooseBt);
Button.OnClickListener mOkOnClickListener2 = new Button.OnClickListener()
{
public void onClick(View v) {
Log.v("hhhhhhh", ""+showTv[0].getText());
Toast.makeText(context,"abc"+showTv[0].getText(), Toast.LENGTH_LONG).show();
}
};
btn2.setOnClickListener(mOkOnClickListener2);
return rowView;
}
}
Activty：
import .......;
public class ActivityMain extends Activity {
ListView listview;
List<Map<String,Object>> data;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTitle("My work");
prepareData();
listview =new ListView(this);
MySimpleAdapter adapter=new MySimpleAdapter(this,data,R.layout.item,new String[] {"uu"},new int[]{R.id.showTv});
listview.setAdapter(adapter);
setContentView(listview);
}
private void prepareData(){
data=new ArrayList<Map<String,Object>>();
Map<String,Object> item;
item=new HashMap<String,Object>();
item.put("uu", "hello");
data.add(item);
item=new HashMap<String,Object>();
item.put("uu", "myyou");
data.add(item);
item=new HashMap<String,Object>();
item.put("uu", "piero");
data.add(item);
}
}
Thanks for that Man that is so kind to provide this AWESOME yet Mightiest tutorial.... which anyone here couldn't give to the noobs....
