我想在我的项目中实现共享操作,但是当我使用MenuItem时,它给出运行时错误而不是使用MenuItemCompat,但是它也给出了错误.
这是我的代码：
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_third_,menu);
MenuItem menuItem = menu.findItem(R.id.menu_item_share);
mShareActionProvider = (ShareActionProvider) menuItem.getActionProvider();
mShareActionProvider.setShareIntent(getDefaultShareIntent());
return true;
}
public Intent getDefaultShareIntent (){
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_SUBJECT,"SUBJECT");
shareIntent.putExtra(Intent.EXTRA_TEXT,"Extra Text");
return shareIntent;
}
解决方法
我相信你已经为你的活动分类了AppCompatActivity,因为你得到了这个错误,请使用下面的代码
在您的活动中初始化ShareActionProvider
import android.support.v7.widget.ShareActionProvider;
import android.support.v4.view.MenuItemCompat;
private ShareActionProvider mShareActionProvider;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main,menu);
// Locate MenuItem with ShareActionProvider
MenuItem item = menu.findItem(R.id.action_share);
// Fetch and store ShareActionProvider
mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item);
mShareActionProvider.setShareHistoryFileName(ShareActionProvider.DEFAULT_SHARE_HISTORY_FILE_NAME);
// Set share Intent.
// Note: You can set the share Intent afterwords if you don't want to set it right now.
mShareActionProvider.setShareIntent(createShareIntent());
// Return true to display menu
return true;
}
// Create and return the Share Intent
private Intent createShareIntent() {
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT,"http://play.google.com/store/apps/details?id=pk.nimgade.Bostan.Train.Schedule");
Intent intent = Intent.createChooser(shareIntent,"Share");
return shareIntent;
}
这就是你的xml视图的样子
<item
android:id="@+id/action_share"
app:actionProviderClass="android.support.v7.widget.ShareActionProvider"
app:showAsAction="always"
android:title="Share" />
请确保你的SDK更新,在这个特殊的情况下,我确实碰到了,当你不知道缺少什么时,这是令人讨厌的
