Android 调用系统的分享

public class ShareManager {

    //分享文件
    public static void shareFiles(Context context, List<File> fileList) {
        if(context == null || fileList == null || fileList.size() < 1) {
            return;
        }
        List<Uri> uriList = new ArrayList();
        for(File file : fileList) {
            Uri uri = Uri.fromFile(file);
            uriList.add(uri);
        }
        Intent intent = null;
        boolean isMultiple = uriList.size() > 1;
     //是否批量分享
        if(isMultiple) {
            intent = new Intent(Intent.ACTION_SEND_MULTIPLE);
            intent.setType("**");
            intent.putExtra(Intent.EXTRA_STREAM,uriList.get(0));
        }
        context.startActivity(Intent.createChooser(intent, "Choose a channel to share your files..."));
    }
    //分享图片
    public static void shareImage(Context context, File imageFile) {
        if(context == null || imageFile == null) {
            return;
        }
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setType("image/*");
        Uri uri = Uri.fromFile(imageFile);
        intent.putExtra(Intent.EXTRA_STREAM, uri);
        context.startActivity(Intent.createChooser(intent, "Choose a channel to share your image..."));
    }
    //分享文字
    public static void shareText(Context context, String text) {
