Question

我想请求您关于Android内置摄像头界面的帮助

当我点击捕获时，屏幕捕获（意味着它冻结）但是，当我点击确定时，它会挂起。它假设回到主界面，但它没有。当我按下取消时，它会强行关闭。代码很长，但这是我的倾听者：

 @Override
     protected void onActivityResult(int requestCode, int
 resultCode, Intent data) 
     {
      super.onActivityResult(requestCode,
 resultCode, data);
      Double x = null;
      Toast.makeText(mContext, x.toString(),Toast.LENGTH_LONG);
         if (resultCode == Activity.RESULT_OK) {
             switch (requestCode) {
             case CAMERA_PIC_REQUEST:

                 image.setImageURI(uri);
                 break;

             }
         }
}

感谢..

这是调用相机界面的意图。

Intent intentCamera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(intentCamera, CALL_CAMERA);

`protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent){
if(requestCode == CALL_CAMERA && resultCode == RESULT_OK) 
{ 
        if(imageReturnedIntent.getAction() != null)
    {
                // display image received on the view
                Bundle newBundle = imageReturnedIntent.getExtras();
                newBitmap = (Bitmap) newBundle.get("data");

                if(newBitmap != null) 
                {       
                        ImageView imageViewProfilePicture = (ImageView) this.findViewById(R.id.imageViewProfilePicture);
                        imageViewProfilePicture.setImageBitmap(newBitmap);
                        imageViewProfilePicture.invalidate();
        }
    }
}}`

解决！ startActivityForResult（）子需要在类中。我把我放在我的onCreate子里面的onclick里面。谢谢你们：D
