我有一个活动，其中有一个按钮。当我按一下按钮它重定向我的图片库。我想使用图像视图，以显示在下一个活动的选择的图像。但它不显示图像。视图是关闭时，图像设置屏幕。

I have an activity, which has a button. When I click on the button it redirects me to the image gallery. I want to show the selected image in the next activity using an image view. But it is not displaying the image. The view is off screen when the image is set.

我的code选择图像和运动对下一如下。我使用没有历史在我的活动真的。

My code for selecting image and moving on next is given below. I am using no history true in my activities.

  @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

     if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
            && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();
        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();
        if (!(picturePath.equals(""))) {
            Intent intent = new Intent();
            intent.setClass(MainActivity.this, ImageInGellary.class);
            intent.putExtra("picturePath", picturePath);
            startActivity(intent);

        }
    }
}
