Imageview没有显示所有图像(Imageview not showing all image)

 您好我正在使用图库在Android应用程序中显示图像。 我在显示图像时遇到问题。 有些图像显示有些不是。 
 
 我的适配器代码如下： 
 
ImageView iv;
            LinearLayout layoutnew = new LinearLayout(getApplicationContext());
            layoutnew.setOrientation(LinearLayout.VERTICAL);

            if (convertView == null)
            {
                iv = new ImageView(ctx);
                iv.setBackgroundDrawable(m_docs_ids[arg0]);
                iv.setScaleType(ImageView.ScaleType.FIT_XY);
                int temp =(int) (height/1.7f);
                int temp_y = (int) ((3*temp)/2.0f);
                iv.setLayoutParams(new LayoutParams( LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT ));

            }


 else
            {
                iv = (ImageView) convertView;
            }
            TextView tv = new TextView(ctx);

       //     tv.setText(m_docs.get(arg0).DocPath);
            tv.setTextColor(0xFFFFFFFF);
            tv.setPadding(0, 15, 0, 0);
            tv.setTag(arg0);
            tv.setTextSize(18);
            tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT ));
            tv.setGravity(Gravity.CENTER);
            layoutnew.addView(iv);
            layoutnew.addView(tv);

            return layoutnew;
 
 m_docs_id是可绘制类型的列表。 我调试它，发现它正在进入正确的。 画廊显示黑色的图像未显示。 
 
 我发现放置在DCIM文件夹中的图片没有显示。 显示所有其他图像 

Hello i am showing images in android app using gallery. I am having problem in displaying images. Some images are displayed some are not.
 
My adapter code is as follows:
 
ImageView iv;
            LinearLayout layoutnew = new LinearLayout(getApplicationContext());
            layoutnew.setOrientation(LinearLayout.VERTICAL);

            if (convertView == null)
            {
                iv = new ImageView(ctx);
                iv.setBackgroundDrawable(m_docs_ids[arg0]);
                iv.setScaleType(ImageView.ScaleType.FIT_XY);
                int temp =(int) (height/1.7f);
                int temp_y = (int) ((3*temp)/2.0f);
                iv.setLayoutParams(new LayoutParams( LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT ));

            }


 else
            {
                iv = (ImageView) convertView;
            }
            TextView tv = new TextView(ctx);

       //     tv.setText(m_docs.get(arg0).DocPath);
            tv.setTextColor(0xFFFFFFFF);
            tv.setPadding(0, 15, 0, 0);
            tv.setTag(arg0);
            tv.setTextSize(18);
            tv.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT ));
            tv.setGravity(Gravity.CENTER);
            layoutnew.addView(iv);
            layoutnew.addView(tv);

            return layoutnew;
 
m_docs_id is a list of drawable type. i have debug it and found that it is getting correct entry. gallery is showing black for images which are not shown.
 
I found put that pictures placed in DCIM folders are not shown. all other images are shown
