Android app - Adding a "share" button to share the app on social networks
提问by david
I have an app, and I'd like to add a share button to it. Once the button is clicked, I'd like it to open the following window:
我有一个应用程序，我想为它添加一个共享按钮。单击按钮后，我希望它打开以下窗口：
Then the user will choose where to share it and it will display the following default message: "Just found this great app! Find it here:https://play.google.com/store/apps/details?id=com.ideashower.readitlater.pro"
然后用户将选择在哪里分享它，它会显示以下默认消息：“刚刚找到这个很棒的应用程序！在这里找到它：https: //play.google.com/store/apps/details?id=com.ideashower .readitlater.pro"
Can you please tell me how to do it?
你能告诉我怎么做吗？

Solution 1: Launch ACTION_SEND Intent
解决方案 1：启动 ACTION_SEND Intent
When launching a SEND intent, you should usually wrap it in a chooser (through createChooser(Intent, CharSequence)), which will give the proper interface for the user to pick how to send your data and allow you to specify a prompt indicating what they are doing.
在启动 SEND 意图时，您通常应该将它包装在一个选择器中（通过createChooser(Intent, CharSequence)），这将为用户提供适当的界面来选择如何发送您的数据，并允许您指定一个提示，指示他们的内容是做。
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
# change the type of data you need to share,
# for image use "image/*"
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, URL_TO_SHARE);
startActivity(Intent.createChooser(intent, "Share"));
Solution 2: Use ShareActionProvider
解决方案 2：使用 ShareActionProvider
If you are just looking to add a Share button in Overflow Menu, also have a look at ShareActionProvider.
如果您只是想在溢出菜单中添加共享按钮，还可以查看ShareActionProvider。
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.share, menu);
MenuItem item = menu.findItem(R.id.share_item);
actionProvider = (ShareActionProvider) item.getActionProvider();
// Create the share Intent
String shareText = URL_TO_SHARE;
Intent shareIntent = ShareCompat.IntentBuilder.from(this)
.setType("text/plain").setText(shareText).getIntent();
actionProvider.setShareIntent(shareIntent);
return true;
}
Hope this helps. :)
希望这可以帮助。:)

As explained on Android Developers on this link: http://developer.android.com/training/sharing/shareaction.html
正如 Android 开发人员在此链接上所解释的：http: //developer.android.com/training/sharing/shareaction.html
you have to add this menu item:
你必须添加这个菜单项：
<item
android:id="@+id/menu_item_share"
android:showAsAction="ifRoom"
android:title="Share"
android:actionProviderClass=
"android.widget.ShareActionProvider" />
Then add the following code in Activity:
然后在Activity中添加如下代码：
private ShareActionProvider mShareActionProvider;
...
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate menu resource file.
getMenuInflater().inflate(R.menu.share_menu, menu);
// Locate MenuItem with ShareActionProvider
MenuItem item = menu.findItem(R.id.menu_item_share);
// Fetch and store ShareActionProvider
mShareActionProvider = (ShareActionProvider) item.getActionProvider();
// Return true to display menu
return true;
}
// Call to update the share intent
private void setShareIntent(Intent shareIntent) {
if (mShareActionProvider != null) {
mShareActionProvider.setShareIntent(shareIntent);
}
}
