本文介绍了一个自定义的GridView适配器实现方法，并展示了如何设置点击监听器以启动新的活动。通过示例代码详细解释了如何创建适配器类、填充视图以及响应用户的点击操作。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<GridView android:id="@+id/grid" android:numColumns="2"
android:horizontalSpacing="20dip" android:verticalSpacing="20dip"
android:stretchMode="columnWidth" android:layout_width="fill_parent" android:layout_height="fill_parent" />
</LinearLayout>

GridView grid = (GridView) findViewById(R.id.grid); grid.setAdapter(new HomeScreenShortcutAdapter());
grid.setOnItemClickListener(new OnItemClickListener() {

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

startActivity(i); // Specify activity through Intent i
}
});

public class HomeScreenShortcutAdapter extends BaseAdapter {

HomeScreenShortcutAdapter() {

}

@Override
public int getCount() {
return 0;
}

@Override
public Object getItem(int position) {
return null;
}

@Override
public long getItemId(int position) {
return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView tv;
final Object data = getItem(position);

if (convertView == null) {

tv = new TextView(getApplicationContext());
tv.setGravity(Gravity.CENTER);

} else {
tv = (TextView) convertView;
}

Drawable icon = data.icon;
CharSequence title = data.title;

tv.setCompoundDrawablesWithIntrinsicBounds(
null, icon, null, null);
tv.setText(title);
tv.setTag(data);

return tv;
}

}
