Answer 1

您可能需要在项目的res＆gt;菜单目录中为共享菜单创建一个xml文件，

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/share"
        android:icon="@drawable/ic_action_share" // share button icon.
        android:showAsAction="always"
        android:title="@string/action_share">
    </item>

</menu>

在你的java文件中，

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.desc_xml, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int itemId = item.getItemId();

        if (itemId == R.id.share) {
            shareNews();
        }

        return super.onOptionsItemSelected(item);
    }

这是分享新闻的方法，

    private void shareNews() {
        Intent shareIntent = new Intent(Intent.ACTION_SEND);
        shareIntent.setType("text/plain");
        shareIntent.putExtra(Intent.EXTRA_TEXT, "Put Data Here");
        startActivity(Intent.createChooser(shareIntent,getString("How do you want to share")));
    }

这个问题已经回答了，但无论如何，这是一个有效的解决方案：

片段/活动中的

：

private ShareActionProvider mShareActionProvider;

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    getActivity().getMenuInflater().inflate(R.menu.deal_detail, menu);

    // Locate MenuItem with ShareActionProviderr
    MenuItem item = menu.findItem(R.id.action_share);

    // Fetch and store ShareActionProvider
    mShareActionProvider = (ShareActionProvider) item.getActionProvider();

    mShareActionProvider.setShareIntent(getShareIntent());
}

// Create the share intent
private Intent getShareIntent() {
    Intent sharingIntent = new Intent(Intent.ACTION_SEND);
    sharingIntent.setType("text/plain");
    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "yoursubject");
    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "yourtext);
    return sharingIntent;
}
