[英]Set onclick listener on every Grid View list
更新:我已經通過使用if條件或切換大小寫找到了答案,謝謝!
我想在每個網格視圖列表上創建onclick偵聽器。
當我單擊列表時,它將使一個類成為一個意圖,但是當我單擊另一個列表時,將對另一個類做出一個意圖,另一個列表也將成為一個意圖。
FirstFragment.java
public class FirstFragment extends Fragment {
View myView;
GridView gridView;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
myView = inflater.inflate(R.layout.first_layout, container, false);
gridView = (GridView) myView.findViewById(R.id.operview);
gridView.setAdapter(new FirstAdapter(myView.getContext())); // uses the view to get the context instead of getActivity().
return myView;
}
}
FirstAdapter.java
public class FirstAdapter extends BaseAdapter
{
private List<Item> items = new ArrayList<Item>();
private LayoutInflater inflater;
public FirstAdapter(Context context)
{
inflater = LayoutInflater.from(context);
items.add(new Item("Indosat", R.drawable.ic_indosat));
items.add(new Item("Telkomsel ", R.drawable.ic_telkomsel));
items.add(new Item("XL", R.drawable.ic_xl));
items.add(new Item("Axis", R.drawable.ic_axis));
items.add(new Item("Tri", R.drawable.ic_tri));
items.add(new Item("Tri", R.drawable.ic_smartfren));
}
@Override
public int getCount() {
return items.size();
}
@Override
public Object getItem(int i)
{
return items.get(i);
}
@Override
public long getItemId(int i)
{
return items.get(i).drawableId;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup)
{
View v = view;
ImageView picture;
TextView name;
if(v == null)
{
v = inflater.inflate(R.layout.first_layout_item, viewGroup, false);
v.setTag(R.id.picture, v.findViewById(R.id.picture));
v.setTag(R.id.text, v.findViewById(R.id.text));
}
picture = (ImageView)v.getTag(R.id.picture);
name = (TextView)v.getTag(R.id.text);
Item item = (Item)getItem(i);
picture.setImageResource(item.drawableId);
name.setText(item.name);
return v;
}
private class Item
{
final String name;
final int drawableId;
Item(String name, int drawableId)
{
this.name = name;
this.drawableId = drawableId;
}
}
}

謝謝..
固定..
我將此代碼添加到FirstFragment.java中,以在每個gridview項上創建onclick偵聽器。
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> a, View v, int position,
long id) {
if (position == 0) {
Intent def = new Intent(getActivity(), PulsaIndosat.class);
startActivity(def);
} else if (position == 1) {
Intent abc = new Intent(getActivity(), PulsaTelkomsel.class);
startActivity(abc);
} else if (position == 2) {
Intent abc = new Intent(getActivity(), PulsaXlAxis.class);
startActivity(abc);
} else if (position == 3) {
Intent abc = new Intent(getActivity(), PulsaXlAxis.class);
startActivity(abc);
} else if (position == 4) {
Intent abc = new Intent(getActivity(), PulsaTri.class);
startActivity(abc);
} else if (position == 5) {
Intent abc = new Intent(getActivity(), PulsaSmartfren.class);
startActivity(abc);
}
}
});
謝謝!
