how to use onclicklistener for grid view

Question

i used gridview to display numbers, so if i click on any number the next activity should start. i tried this code but the app crashes

         private GridView gridView = null;

      gridView.setOnClickListener(new OnClickListener()

    {
              public void onClick(View v5) 

        {
            setContentView(R.layout.Abc);
            Intent myIntent = new 

 Intent(getApplicationContext(),Abc.class);
            startActivity(myIntent);

        }
    });

here is the xml code for gridview

     <GridView
    android:id="@+id/month_gridView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/calendar_days"
    android:layout_marginLeft="7dp"
    android:layout_marginRight="8dp"
    android:background="@color/grid_background"
    android:fadingEdge="none"
    android:gravity="top|left"
    android:horizontalSpacing="2dp"
    android:listSelector="@android:color/transparent"
    android:numColumns="7"
    android:padding="1dp"
    android:stretchMode="columnWidth"
    android:verticalSpacing="2dp">
</GridView>

Answer 1

GridView is Like a ListView

You should use some thing like this

gridView.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {

            // DO something

        }
    });

the code is not perfect

for reference see http://developer.android.com/reference/android/widget/GridView.html

Answer 2

You should use onItemClickListener instead of onClickListener.
