Android系统分享的注册和调起
转载注明出处chendong_
现在有很多第三方分享平台，比如友盟，shareSdk等，其实我们在相册长按图片点击发送／分享就会调起很多应用，让你选择可以分享到很多平台，比如QQ，微信等，相对使用第三方要简陋一点，但是因为是系统的集成起来也相对简单，不需要导入各种包。。
注册系统的分享，你可以在用户点击分享／发送按钮时调起你的应用，使用户可以将图片和文字分享到你的App.
<activity
android:name=".activity.SysShareActivity"
android:label="我的分享"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.SEND"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="image/*"/>
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/plain"/>
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND_MULTIPLE"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="image/*"/>
</intent-filter>
</activity>
然后分享一个我写的工具类，可以轻松实现系统分享的注册和调起

如何处理分享得到数据？
shareSysUtils = ShareSysUtils.get(self);
shareSysUtils.handleShare(new ShareSysUtils.OnShareDataOkListener() {
@Override
public void OnHandleOk(int type, List<String> list, String title, String content) {
if (type == ShareSysUtils.TYPE_TEXT) {
Log.e("chendong", "分享文本是 " + title + " " + content);
} else if (type == ShareSysUtils.TYPE_IMAGE) {
Log.e("chendong", "分享图片是 " + list.toString());
}
}
});
如何发起分享？
public void ShareImg(View view) {
shareSysUtils.shareSingleImage("我是图片路径path");
}
public void ShareTxt(View view) {
shareSysUtils.shareText("我是title", "我是content");
}
