Android 侧滑菜单与ActionBar和ShareActionProvider演示

Posted 2020-08-20

用于

AppCompatActivity

XML配置：

for menu:

xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity"

for items:
app:actionProviderClass="android.support.v7.widget.ShareActionProvider"

安卓后台代码：

调用ShareActionProvider时需要注意

MenuItem menuItem = menu.findItem(R.id.share);

ShareActionProvider sap = (ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);

sap.setShareIntent(getDefaultIntent());

        //得到标题集合
