How to add gridview setOnItemClickListener
android, android-gridview
Solution
You are requesting click on the item(not on the button inside the item) so need to change your child XML layout
from
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<Button
android:id="@+id/city"
android:layout_width="183dp"
android:layout_height="90dp"
android:textSize="19sp"
android:textStyle="bold"
android:text="Code\n\nCity"
android:gravity="center"
android:background="@drawable/city_btn_tablet" />
</RelativeLayout>
to
<?xml version="1.0" encoding="utf-8"?>
<Button
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/city"
android:layout_width="183dp"
android:layout_height="90dp"
android:textSize="19sp"
android:clickable="true"
android:textStyle="bold"
android:text="Code\n\nCity"
android:gravity="center"
android:background="@drawable/city_btn_tablet" />
or you can add ClickListener inside adapter
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
gridView =new View(mContext);
gridView = inflater.inflate(R.layout.gridview_members, null);
Button city = (Button) gridView.findViewById(R.id.city);
city.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Toast here
}});
return gridView;
}
Problem
I have a GridView with 81 buttons on it. I want to add clicklistener to this gridview but it is not available. I have added the OnItemClickListener but it is not working and I cannot understand why. There is no error with the code. The only thing not working is the OnItemClickListener. My gridview children which has a button on it(gridview_members.xml); ``` <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <Button android:id="@+id/city" android:layout_width="183dp" android:layout_height="90dp" android:textSize="19sp" android:textStyle="bold" android:text="Code\n\nCity" android:gravity="center" android:background="@drawable/city_btn_tablet" /> </RelativeLayout> ``` My ImageAdapter class; ``` public class ImageAdapter extends BaseAdapter { private Context mContext; public ImageAdapter(Context c) { mContext = c; } public int getCount() { return 81; } public Object getItem(int position) { return null; } public long getItemId(int position) { return 0; } @Override public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View gridView; gridView =new View(mContext); gridView = inflater.inflate(R.layout.gridview_members, null); Button city = (Button) gridView.findViewById(R.id.city); return gridView; } } ``` Gridview implementation on activity_main.xml ; ``` <GridView android:id="@+id/gridview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:horizontalSpacing="5dp" android:verticalSpacing="5dp" android:gravity="center" android:stretchMode="columnWidth" android:numColumns="6" > </GridView> ``` And finally my MainActivity.java file; ``` public class MainActivity extends Activity{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); GridView gridview = (GridView) findViewById(R.id.gridview); gridview.setAdapter(new ImageAdapter(this)); gridview.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View v, int position, long id) { Toast.makeText(MainActivity.this, "" + position, Toast.LENGTH_SHORT).show(); } }); } } ```
