如何在Android的添加监听器排? [英] how to add listener in android on row?
问题描述
我试图让使用自定义适配器和片段的自定义列表。我能够做一个列表视图。但有一个问题,我有一个形象按钮,并在一排文本视图。我想听听该行的单击事件,以及图像按钮的单击事件。换句话说,我需要添加一个监听单击图像按钮,这是该行present当点击该行时将听取和
下面是我的code:

I am trying to make a custom list using a custom adapter and a fragment. I am able to make a list view. But there is one problem, I have an image button and a text view in a row. I want to listen to the click event of the row, as well as the Image button's click event. In other words, I need to add a listener that will listen when the row is clicked and when the image button that is present on the row is clicked.
Here is my code:
custom adapter
public class CustomAdapter extends BaseAdapter implements View.OnClickListener {
private Activity activity;
private ArrayList data;
private static LayoutInflater inflater = null;
public CustomAdapter(Activity a, ArrayList d) {
/********** Take passed values **********/
activity = a;
data = d;
inflater = (LayoutInflater) activity.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
if (data.size() <= 0)
return 1;
return data.size();
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public void onClick(View v) {
Log.d("row is click","row click");
}
/*********
* Create a holder Class to contain inflated xml file elements
*********/
public static class ViewHolder {
public TextView text;
public ImageButton imageButton;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
ViewHolder holder;
if (convertView == null) {
/****** Inflate tabitem.xml file for each row ( Defined below ) *******/
vi = inflater.inflate(R.layout.row_layout, null);
/****** View Holder Object to contain tabitem.xml file elements ******/
holder = new ViewHolder();
holder.text = (TextView) vi.findViewById(R.id.station_name);
holder.imageButton = (ImageButton) vi.findViewById(R.id.favorite);
/************ Set holder with LayoutInflater ************/
vi.setTag(holder);
} else
holder = (ViewHolder) vi.getTag();
if (data.size() <= 0) {
holder.text.setText("No Data");
} else {
String string = (String) data.get(position);
/************ Set Model values in Holder elements ***********/
holder.text.setText(string);
}
return vi;
}
}

fragmentone.java
public class Fragmentone extends Fragment{
ArrayList<String> name;
boolean isPressed=false;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_one, container, false);
name=new ArrayList<String>();
name.add("First Station");
name.add("Second Station");
ListView listView = (ListView) view.findViewById(R.id.list_view);
CustomAdapter customAdapter =new CustomAdapter(getActivity(),name);
listView.setAdapter(customAdapter);
return view;
}
}
Check it out this code, if you have any trouble to understand comment
public class CustomAdapter extends BaseAdapter {
private Activity activity;
private ArrayList data;
private static LayoutInflater inflater = null;
public CustomAdapter(Activity a, ArrayList d) {
/********** Take passed values **********/
activity = a;
data = d;
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
if (data.size() <= 0)
return 1;
return data.size();
}
@Override
public Object getItem(int position) {
return position;
}
/*********

public static class ViewHolder {
public TextView text;
public ImageButton imageButton;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View vi = convertView;
ViewHolder holder;
if (convertView == null) {
/****** Inflate tabitem.xml file for each row ( Defined below ) *******/
vi = inflater.inflate(R.layout.row_layout, null);
/****** View Holder Object to contain tabitem.xml file elements ******/
holder = new ViewHolder();
holder.text = (TextView) vi.findViewById(R.id.station_name);
holder.imageButton = (ImageButton) vi.findViewById(R.id.favorite);
/************ Set holder with LayoutInflater ************/
vi.setTag(holder);
} else
holder = (ViewHolder) vi.getTag();
if (data.size() <= 0) {
holder.text.setText("No Data");
} else {
String string = (String) data.get(position);
/************ Set Model values in Holder elements ***********/
holder.text.setText(string);
}
// this is for overall row click
convertView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
// this is for image button onclick
holder.imageButton.setOnClickListener(new View.OnClickListener() {
@Override

}
});
;
return vi;
}
}
