第一步：
<activity android:name=".activity.ContactGroupShareActivity"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
android:label="@string/app_name">
<intent-filter>
<!--调用共享时，过滤共享文件，此处默认全部 -->
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<!-- 允许所有类型文件-->
<data android:mimeType="*/*" />
</intent-filter>
</activity>
第二步：
/**
* 其他应用调用本分享功能
*/
private void shareFormOtherProg() {
/*比如通过Gallery方式来调用本分享功能*/
Intent intent = getIntent();
Bundle extras = intent.getExtras();
String action = intent.getAction();
if (Intent.ACTION_SEND.equals(action)) {
if (extras.containsKey(Intent.EXTRA_STREAM)) {
try {
// Get resource path from intent
Uri uri = (Uri) extras.getParcelable(Intent.EXTRA_STREAM);
// 返回路径
String path = csc.getRealPathFromURI(this, uri);
System.out.println("path-->" + path);
return;
} catch (Exception e) {
Log.e(this.getClass().getName(), e.toString());
}
} else if (extras.containsKey(Intent.EXTRA_TEXT)) {
return;
}
}
}
/**
* 通过Uri获取文件在本地存储的真实路径
* @param act
* @param contentUri
* @return
*/
public String getRealPathFromURI(Activity act, Uri contentUri) {
// can post image
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = act.managedQuery(contentUri, proj, // Which columns to return
null, // WHERE clause; which rows to return (all rows)
