ImageView:

<ImageView
            android:id="@+id/textiv"
            android:layout_width="10dp"
            android:layout_height="10dp"
            android:src="@drawable/textiv"/>

点击事件:

ImageView imageView = (ImageView)findViewById(R.id.textiv)
Drawable drawable = imageView.getDrawable();
BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;
Bitmap bitmap = bitmapDrawable.getBitmap();
saveImageToGallery(context,drawable);

保存代码:

public static void saveImageToGallery(Context context, Bitmap bitmap) {
    // 首先保存图片
    File appDir = new File(Environment.getExternalStorageDirectory(), "test");
    if (!appDir.exists()) {
        appDir.mkdir();
    }
    String fileName = System.currentTimeMillis() + ".jpg";
    File file = new File(appDir, fileName);
    try {
        FileOutputStream fos = new FileOutputStream(file);
        bmp.compress(CompressFormat.JPEG, 100, fos);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    // 其次把文件插入到系统图库
    try {
        MediaStore.Images.Media.insertImage(context.getContentResolver(),
                file.getAbsolutePath(), fileName, null);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
   //最后通知图库更新
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);//扫描单个文件
    intent.setData(Uri.fromFile(file));//给图片的绝对路径
    context.sendBroadcast(intent);

    Toast.makeText(mContext,"baocun",Toast.LENGTH_SHORT).show();

}
