I'm developing an Android app and I having trouble implementing the share button on the template "Master / detail flow"
When I create the menu on the ItemDetailActivity which extends AppCompatActivity (however, I've also tried extending ActionBarActivity) I get the following error java.lang.ClassCastException: android.widget.ShareActionProvider cannot be cast to android.support.v4.view.ActionProvider in this line:
getMenuInflater().inflate(R.menu.menu_ficha, menu);
Here some code: Java
public class ItemDetailActivity extends AppCompatActivity {
ShareActionProvider mShareActionProvider;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_item_detail);
// Show the Up button in the action bar.
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
if (savedInstanceState == null) {
// Create the detail fragment and add it to the activity
// using a fragment transaction.
Bundle arguments = new Bundle();
arguments.putStringArray(ItemDetailFragment.ARG_ITEM_ID,
getIntent().getStringArrayExtra(ItemDetailFragment.ARG_ITEM_ID));
ItemDetailFragment fragment = new ItemDetailFragment();
fragment.setArguments(arguments);
getSupportFragmentManager().beginTransaction()
.add(R.id.item_detail_container, fragment)
.commit();
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == android.R.id.home) {
NavUtils.navigateUpTo(this, new Intent(this, ItemListActivity.class));
return true;
}
return super.onOptionsItemSelected(item);
}
@Override public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_ficha, menu);
// Access the Share Item defined in menu XML
MenuItem shareItem = menu.findItem(R.id.menu_item_share);
// Access the object responsible for
// putting together the sharing submenu
mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(shareItem);
// Create an Intent to share your content
setShareIntent();
return true;
};
private void setShareIntent() {
if (mShareActionProvider != null) {
// create an Intent with the contents of the TextView
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_SUBJECT, "Testing Oceanbook");
shareIntent.putExtra(Intent.EXTRA_TEXT, ItemDetailFragment.data[1]);
// Make sure the provider knows
// it should work with that Intent
mShareActionProvider.setShareIntent(shareIntent);
}
}
}
And the XML of the menu:
<menu xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:oceanbook="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/menu_item_share"
android:title="Compartir"
oceanbook:showAsAction="ifRoom"
oceanbook:actionProviderClass="android.widget.ShareActionProvider" />
</menu>
Just in case is important, the XML of the Activity:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/item_detail_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ItemDetailActivity"
tools:ignore="MergeRootFrame" />
Could anyone help me please?
