GridView on item click listener
提问by user2796963
gridView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
Toast.makeText(ScenesActivity.this, position + "#Selected",
Toast.LENGTH_SHORT).show();
final Intent intent = new Intent(getApplicationContext(), ScenesDetailActivity.class);
intent.putExtra(TestConstants.SELCTED_SCENE_KEY, position);
startActivity(intent);
}
});
TestConstants.java
测试常量.java
public interface TestConstants {
String SELCTED_SCENE_KEY="SELCTED_SCENE"; }
I want to get ScenesDetailActivity after click the slected scene key. It seems that the above code doesn't work as expected. Can someone help me to slove it? Thanks a lot! Simonides

does the gridView have a custom layout ?
gridView 有自定义布局吗？
if yes, go to the custom layout xml file and change these attributes
如果是，请转到自定义布局 xml 文件并更改这些属性
android:clickable="false"
android:focusable="false"

Here's the cleanest way to do it: call performItemClick() on the GridView from within each button's click listener in your Adapter. That way you can still use the GridView's onItemClickListener like normal.
这是最简洁的方法：从适配器中每个按钮的单击侦听器中调用 GridView 上的 performItemClick()。这样你仍然可以像往常一样使用 GridView 的 onItemClickListener。
// in your ListAdapter
@Override
public View getView(final int position, final View convertView, final ViewGroup parent) {
// set btn to be your item's view
...
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
((GridView) parent).performItemClick(v, position, 0);
}
});
}
