Sharing Simple Data

通过Intent来传递数据。

Sending Simple Data to Other Apps

向多媒体添加文件：

MediaScannerConnection.scanFile(this, new String[]{Environment.getExternalStorageDirectory() + "/" + "Download/20150525_091043.jpg"}, null, new MediaScannerConnection.OnScanCompletedListener() { @Override public void onScanCompleted(String path, Uri uri) { System.out.println("path:"+path); System.out.println("uri:"+uri); } });

调用sancFile()方法后可以在图库中看到Download文件夹。

Adding an Easy Share Action

Android 4.0(API Level 14)或之后的版本，可以使用ShareActionProvider。低版本可以使用android.support.v7.widget.ShareActionProvider。

menu.xml:

<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:support="http://schemas.android.com/apk/res-auto"> <item android:id="@+id/share" support:showAsAction="always" android:title="Share" support:actionProviderClass="android.support.v7.widget.ShareActionProvider"/> </menu>

设置分享Intent:

@Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu,menu); MenuItem item=menu.findItem(R.id.share); mShareActionProvider=(ShareActionProvider) MenuItemCompat.getActionProvider(item); return super.onCreateOptionsMenu(menu); } // Call to update the share intent private void setShareIntent(Intent shareIntent) { if (mShareActionProvider != null) { mShareActionProvider.setShareIntent(shareIntent); }
