Question

我想从viewflipper分享当前正在查看的图片，但我无法获取正在显示的图片的名称，这是我使用的代码：

_current = _current.Right;

如果有人能帮助我，我会非常感激

Answer 1

我已经使用了几次，但据我所知，viewflipper一次只显示其中一个孩子。您应该调用此方法以显示孩子：

viewFlipper.setDisplayedChild(childPosition);

代码中的循环只会设置数组的最后一个图像，如果您希望显示一个应该用于RecyclerView / ListView的图像列表。希望这有帮助！

可能这应该适合你：

public class imagen1 extends Activity {
public float init_x;
private ViewFlipper vf;

int gallery_grid_Images[] = {R.drawable.fondo, R.drawable.fondo2, R.drawable.fondo3,
        R.drawable.fondo4, R.drawable.fondo5
};

ImageView[] views = new ImageView[gallery_grid_Images.length];

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.imagen1);
    ImageView imagePreview = (ImageView) findViewById(R.id.preview);

    vf = (ViewFlipper) findViewById(R.id.viewFlipper);
    for (int i = 0; i < gallery_grid_Images.length; i++) {
        //  This will create dynamic image view and add them to ViewFlipper
        setFlipperImage(gallery_grid_Images[i], i);
    }
    vf.setOnTouchListener(new ListenerTouchViewFlipper());

}

private void setFlipperImage(int res, int index) {
    Log.i("Set Filpper Called", res + "");
    ImageView image = new ImageView(getApplicationContext());
    image.setBackgroundResource(res);
    vf.addView(image);
    views[index] = image;
}

public void compartir (View v) {
    int index = -1;
    for (int i = 0; i < views.length; i++) {
        if (views[i] == (ImageView) vf.getCurrentView())
            index = i;
    }

    if (index == -1) {
        // failed to determine the right index
        Log.w("imagen1", "Could not determine the right index!");
        return; 
    }

    Uri newUri2 = Uri.parse("android.resource://" + getPackageName()
            + "/drawable/" + gallery_grid_Images[index]);
    Intent shareIntent = new Intent();
    shareIntent.setAction(Intent.ACTION_SEND);
    shareIntent.putExtra(Intent.EXTRA_TEXT, "");
    shareIntent.putExtra(Intent.EXTRA_STREAM, newUri2);
    shareIntent.setType("image/jpg");
    shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    startActivity(Intent.createChooser(shareIntent, "Compartir"));

}

}

效果很好，你不知道我多么感谢你的帮助，我只需修改代码中的一部分，因为它给了我错误：

Uri newUri2 = Uri.parse("android.resource://" + getPackageName()
            + "/drawable/" + gallery_grid_Images[i]);

添加索引

 Uri newUri2 = Uri.parse("android.resource://" + getPackageName()
                + "/drawable/" + gallery_grid_Images[index]);

非常感谢你的帮助
