android - 使用 Android 操作栏分享 Intent

Question

我正在使用操作栏上的菜单项，我想通过单击共享图标来共享我的应用程序。当我单击共享图标时，它不起作用。另外，我想在分享时添加文字 "install this app"。

这是我的代码:

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.mainpage, menu);
    MenuItem item = menu.findItem(R.id.menu_item_share);
    mShareActionProvider = (ShareActionProvider) item.getActionProvider();

    return true;
}

private void setShareIntent(Intent shareIntent) {
    if (mShareActionProvider != null) {
        mShareActionProvider.setShareIntent(shareIntent);
    }
}

Mainpage.xml 菜单:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="@+id/menu_item_share"
    android:showAsAction="ifRoom"
    android:title="Share"
    android:icon="@drawable/ic_store"
    android:actionProviderClass="android.widget.ShareActionProvider" />
</menu>

如果您想要一个静态共享 Intent(即，它永远不会改变)，那么您可以将 onCreateOptionsMenu 更新为

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.mainpage, menu);
    MenuItem item = menu.findItem(R.id.menu_item_share);
    mShareActionProvider = (ShareActionProvider) item.getActionProvider();
    // Create the share Intent
    String playStoreLink = "https://play.google.com/store/apps/details?id=" +
        getPackageName();
    String yourShareText = "Install this app " + playStoreLink;
    Intent shareIntent = ShareCompat.IntentBuilder.from(this)
        .setType("text/plain").setText(yourShareText).getIntent();
    // Set the share Intent
    mShareActionProvider.setShareIntent(shareIntent);
    return true;
}
