我需要将位图转换为uri发送，以便在android的图像裁剪器库中使用它？

在这里，我把可绘制视图转换成位图

     mDrawingPad.setVisibility(View.VISIBLE);
                BitmapDrawable ob = new BitmapDrawable(getResources(), 
              bitmapconv);
                DrawingView mDrawingView=new 
             DrawingView(Previewimage.this);
                mDrawingPad.addView(mDrawingView);
                mDrawingView.setBackground(ob);
                mDrawingView.buildDrawingCache();
                drawbitmap=mDrawingView.getDrawingCache();

我需要将其转换为URI以发送到图像裁剪器库

     mDrawingPad.setVisibility(View.VISIBLE);
                BitmapDrawable ob = new BitmapDrawable(getResources(), 
              bitmapconv);
                DrawingView mDrawingView=new 
             DrawingView(Previewimage.this);
                mDrawingPad.addView(mDrawingView);
                mDrawingView.setBackground(ob);
                mDrawingView.buildDrawingCache();
                drawbitmap=mDrawingView.getDrawingCache();

       CropImage.activity(uri).start(Previewimage.this);

这部分代码的作用是：

     mDrawingPad.setVisibility(View.VISIBLE);
                BitmapDrawable ob = new BitmapDrawable(getResources(), 
              bitmapconv);
                DrawingView mDrawingView=new 
             DrawingView(Previewimage.this);
                mDrawingPad.addView(mDrawingView);
                mDrawingView.setBackground(ob);
                mDrawingView.buildDrawingCache();
                drawbitmap=mDrawingView.getDrawingCache();

    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    your_bitmap_image.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = MediaStore.Images.Media.insertImage(your_context.getContentResolver(), your_bitmap_image, "your_title", null);
    Uri uri = Uri.parse(path);

试着替换我在上面提到的区域

     mDrawingPad.setVisibility(View.VISIBLE);
                BitmapDrawable ob = new BitmapDrawable(getResources(), 
              bitmapconv);
                DrawingView mDrawingView=new 
             DrawingView(Previewimage.this);
                mDrawingPad.addView(mDrawingView);
                mDrawingView.setBackground(ob);
                mDrawingView.buildDrawingCache();
                drawbitmap=mDrawingView.getDrawingCache();

如果您正在参加一项活动，请将以下内容替换为“您的上下文”：

     mDrawingPad.setVisibility(View.VISIBLE);
                BitmapDrawable ob = new BitmapDrawable(getResources(), 
              bitmapconv);
                DrawingView mDrawingView=new 
             DrawingView(Previewimage.this);
                mDrawingPad.addView(mDrawingView);
                mDrawingView.setBackground(ob);
                mDrawingView.buildDrawingCache();
                drawbitmap=mDrawingView.getDrawingCache();

MediaStore.Images.Media.insertImage(getContentResolver(), your_bitmap_image, "your_title", null);
        Uri uri = Uri.parse(path);

如果您在片段中：

     mDrawingPad.setVisibility(View.VISIBLE);
                BitmapDrawable ob = new BitmapDrawable(getResources(), 
              bitmapconv);
                DrawingView mDrawingView=new 
             DrawingView(Previewimage.this);
                mDrawingPad.addView(mDrawingView);
                mDrawingView.setBackground(ob);
                mDrawingView.buildDrawingCache();
                drawbitmap=mDrawingView.getDrawingCache();

MediaStore.Images.Media.insertImage(getContext().getContentResolver(), your_bitmap_image, "your_title", null);
        Uri uri = Uri.parse(path);

                mDrawingView.buildDrawingCache();
                drawbitmap=mDrawingView.getDrawingCache();

如果您正在参加一项活动，请将以下内容替换为“您的上下文”：

     mDrawingPad.setVisibility(View.VISIBLE);
                BitmapDrawable ob = new BitmapDrawable(getResources(),

                mDrawingView.buildDrawingCache();
                drawbitmap=mDrawingView.getDrawingCache();

MediaStore.Images.Media.insertImage(getContentResolver(), your_bitmap_image, "your_title", null);
        Uri uri = Uri.parse(path);

如果您在片段中：

     mDrawingPad.setVisibility(View.VISIBLE);
                BitmapDrawable ob = new BitmapDrawable(getResources(), 
              bitmapconv);
                DrawingView mDrawingView=new

MediaStore.Images.Media.insertImage(getContext().getContentResolver(), your_bitmap_image, "your_title", null);
        Uri uri = Uri.parse(path);

使用此方法：

     mDrawingPad.setVisibility(View.VISIBLE);
                BitmapDrawable ob = new BitmapDrawable(getResources(), 
              bitmapconv);

                mDrawingView.buildDrawingCache();
                drawbitmap=mDrawingView.getDrawingCache();

public Uri getImageUri(Context ctx, Bitmap bitmap) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(ctx.getContentResolver(), 
bitmap, "Temp", null);
return Uri.parse(path);
} 

如果您在活动中调用此方法，请按如下方式调用此方法：

     mDrawingPad.setVisibility(View.VISIBLE);
                BitmapDrawable ob = new BitmapDrawable(getResources(), 
              bitmapconv);

                drawbitmap=mDrawingView.getDrawingCache();

 getImageUri(YourClassName.this, yourbitmap);

 getImageUri(getActivity(), yourbitmap);
