Android “如何解决此类型错误”；文件格式不受支持"；向whatsapp共享图像时？

我正在实现一个应用程序，在单击“共享按钮”时将图像共享到whatsapp，根据这个项目，我创建了一个扩展Baseadapter的Imageadapter和一个用于共享图像的活动。因此，当我单击“共享按钮”时，它应该生成“文件格式不受支持”

ImageAdapter.java

public class ImageAdapter extends BaseAdapter {

private Context mContext;
public int getCount() {
    return mThumbIds.length;
}
public Object getItem(int position) {
    return mThumbIds[position];
}
public long getItemId(int position) {
    return 0;
}
public ImageAdapter(Context c) {
    mContext = c;
}

public View getView(final int position, View convertView, ViewGroup parent) {
    ImageView imageView;
    if (convertView == null){
        imageView = new ImageView(mContext);
        imageView.setLayoutParams(new GridView.LayoutParams(80, 80));
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setPadding(15, 15, 15, 15);
        imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Intent intent = new Intent(mContext,FullScreenImage.class);
                intent.putExtra("imageID", mThumbIds[position]);
                mContext.startActivity(intent);
            }
        });


    }
    else{
        imageView = (ImageView) convertView;
    }
    imageView.setImageResource(mThumbIds[position]);
    return imageView;
}

private Integer[] mThumbIds = {
        R.mipmap.h1, R.mipmap.h2,
        R.mipmap.h3, R.mipmap.h4,
        R.mipmap.h5,R.mipmap.h6,
        R.mipmap.h7,R.mipmap.h8
        ,R.mipmap.h9,R.mipmap.h10
        ,R.mipmap.h11,R.mipmap.h12
        ,R.mipmap.h13,R.mipmap.h14
        ,R.mipmap.h15
};
}

如果有人知道问题出在哪里，请告诉我。

提前感谢…

尝试将.jpg附加到图像文件名中。文件名应具有有效的图像扩展名，如.jpg或.jpeg

在onClick中，尝试实现以下代码：

Intent intent = new Intent(mContext,FullScreenImage.class);
                intent.putExtra("imageID", mThumbIds[position]+".jpg");
                mContext.startActivity(intent);

您可以使用下面的代码片段仅向whatsapp共享图像

Uri imageUri = Uri.parse("android.resource://com.v1.sensoft.halloween/mipmap"+imageRes);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
//Target whatsapp:
shareIntent.setPackage("com.whatsapp");
//Add Image URI
shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
shareIntent.setType("image/jpeg");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(shareIntent);

我明白你的意思。在您的情况下，首先您必须在sdcard中的AsyncTaskStore的帮助下从Uri下载图像，并使用以下代码发送到该图像

当你们从SD卡中选择路径时，它会自动检测图像扩展本身，无需担心

try {
                    Intent sendIntent = new Intent();
                    sendIntent.setAction(Intent.ACTION_SEND);
                    sendIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    sendIntent.putExtra(Intent.EXTRA_TEXT, "your title");
                    sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("your image path"));
                    sendIntent.setType("image/*");
                    sendIntent.setPackage("com.whatsapp");
                    startActivity(sendIntent);
                } catch (Exception e) {
                    e.printStackTrace();
                }

您必须从url下载图像到SD卡；发送从SD卡到whatsapp的路径

不适用于我…你看到我的代码了吗？我正在使用捆绑包从图像适配器获取特定图像。不适用于我…你看到我的代码了吗？我正在使用捆绑包从图像适配器获取特定图像。@Vishal..请详细说明我正在通过捆绑包从图像适配器获取所有图像对于whatsapp图像共享，我得到了在activity@Vishal…请详细说明我正在通过Bundle将所有图像从ImageAdapter获取到myActivity，对于whatsapp图像共享，我获取在activity中打开的特定图像
