Это отображение двумерного массива в виде списка. Вот мой исходный код, в котором я реализовал двумерный массив в виде списка
Класс моего адаптера: -
public class MyArrayAdapter extends ArrayAdapter<List>{
QuickActionDemo quickActionDemo;
public Activity context;
public List<List> list;
int CAMERA_PIC_REQUEST=10;
private int selectedPos = -1;
int clickPosition,rowPosition;
Camera camera;
private static final String TAG = "CameraDemo";
public MyArrayAdapter(Activity context,List<List> list) {
super(context,R.layout.attach_pic,list);
this.context = context;
this.list = list;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position+1;
}
static class ViewHolder {
public TextView tv1,tv2,tv3;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View rowView = null;
final ViewHolder holder = new ViewHolder();
if (convertView == null) {
LayoutInflater inflator = context.getLayoutInflater();
rowView = inflator.inflate(R.layout.attach_pic, null);
holder.tv1 = (TextView) rowView.findViewById(R.id.defectpic);
holder.tv2 = (TextView) rowView.findViewById(R.id.no_of_uploded_pics);
holder.tv3 = (TextView) rowView.findViewById(R.id.camera);
holder.tv3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
// Intent in = new Intent(getContext(),QuickActionDemo.class);
// context.startActivityForResult(in,0);
}
});
rowView.setTag(holder);
List itemVal1 = (List)getItem(position);
String st1 = (String)itemVal1.get(0);
holder.tv1.setText(st1);
List itemVal2 = (List)getItem(position);
String st2 = (String)itemVal2.get(1);
holder.tv2.setText(st2);
} else {
rowView = convertView;
((ViewHolder) rowView.getTag()).tv1.setTag(list.get(position));
((ViewHolder) rowView.getTag()).tv2.setTag(list.get(position));
((ViewHolder) rowView.getTag()).tv3.setTag(list.get(position));
}
return rowView;
}
@Override
public int getItemViewType(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public int getViewTypeCount() {
// TODO Auto-generated method stub
return list.size();
}
}
Вот мой класс активности: -
public class MyActivity extends ListActivity {
Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
// requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); // to hide the virtual keyboard
setContentView(R.layout.defect_pic_listview);
try{
ArrayAdapter<List> adapter = new MyArrayAdapter(this,makeList());
setListAdapter(adapter);
}
}
private List<List> makeList(){
List<List> all = new ArrayList();
String[] newArray1 = {"Defect Picture1", "2"};
List<String> newListObject1 = Arrays.asList(newArray1);
String[] newArray2 = {"Defect Picture2","1"};
List<String> newListObject2 = Arrays.asList(newArray2);
String[] newArray3 = {"Defect Picture3","4"};
List<String> newListObject3 = Arrays.asList(newArray3);
String[] newArray4 = {"Defect Picture4","1"};
List<String> newListObject4 = Arrays.asList(newArray4);
String[] newArray5 = {"Defect Picture5","3"};
List<String> newListObject5 = Arrays.asList(newArray5);
all.add(newListObject1);
all.add(newListObject2);
all.add(newListObject3);
all.add(newListObject4);
all.add(newListObject5);
return all;
}
}
