android – 在按钮单击时立即打开文件夹(SD卡)中的所有图像

发生了什么：如果文件夹有多个图像,则应用程序仅显示单个图像.

按钮单击方法代码：

private void showGallery() {

    if ((personName.getText().toString() != null && !personName.getText().toString().isEmpty())
            && (mobileNo.getText() != null && !mobileNo.getText().toString().isEmpty())) {

        File folder = new File(Environment.getExternalStorageDirectory(),photoPath + personName.getText().toString() + "_" + mobileNo.getText().toString() + "/");

        File[] allFiles = folder.listFiles();
        if (allFiles != null && allFiles.length > 0) {
            for (File child : allfiles) {
                new SingleMediaScAnner(getActivity(),child);
            }
        }
    }    
}

SingleMediaScAnner代码：

public class SingleMediaScAnner implements MediaScAnnerConnection.MediaScAnnerConnectionClient {

        private MediaScAnnerConnection mMs;
        private File mFile;

        public SingleMediaScAnner(Context context,File f) {
            mFile = f;
            mMs = new MediaScAnnerConnection(context,this);
            mMs.connect();
        }

        public void onMediaScAnnerConnected() {
            mMs.scanFile(mFile.getAbsolutePath(),"image/*");
        }

        public void onScanCompleted(String path,Uri uri) {
            Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
            intent.setData(uri);
            startActivity(intent);
            mMs.disconnect();
        }
    }
}
