你好朋友......
我目前正在尝试使用隐式意图制作一个对话框，我想在其中显示我的对话框，例如 whatsApp(个人资料照片屏幕)，并且在此屏幕中，whatsApp 正在使用名为删除照片"的额外字段.当我尝试制作相同类型的屏幕对话框时，我无法添加这个额外的字段(删除照片").我已经完成了所有代码.它对于对话框中的三个选项(例如(图库，照片，相机))工作正常，我无法在 onActivityResult() 中处理所有这些.我正在发送我已经非常努力的所有源代码，但我无法找到这样做的解决方案.plz.....朋友们帮我解决这个问题.
I am currently trying to make a Dialog using Implicit Intent where i want to show my Dialog like whatsApp(Profile Photo Screen) and in this screen whatsApp are using extra field named as "Remove Photo". When i try to make same type of screen Dialog then i am unable to add this extra field("Remove Photo"). i have done all code. its working fine for three option in Dialog like(Gallery,Photo,Camera) and i am unable to handle these all in onActivityResult() . I am sending my all source code i have tried much hard , but i am not able to find the solution to do so. plz..... friends help me out from this.
在这段代码中，我只是创建了一个名为 openFileChooser() 的方法，我在其中编写了所有用于创建对话框屏幕的代码并在 onActivityResult() 中处理此结果
In this code i am simply create a method named as openFileChooser() in which i have write all the code for creating Dialog Screen and handle this outcomes in onActivityResult()
这是我的代码
ProfilePhotoActivity.java

}

Toast.makeText(getApplicationContext(), "No extras to retrieve!", Toast.LENGTH_SHORT).show();

// update the image view with the newly created drawable
imgCamera.setImageDrawable(thumbnail);
}
}
else if (resultCode == RESULT_CANCELED) {
Toast.makeText(getApplicationContext(), "Cancelled", Toast.LENGTH_SHORT).show();
}
}
}
}
@Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
ProfilePhotoActivity.this.finish();
}
}
这看起来会是个问题:
if(requestCode==FILECHOOSER_RESULTCODE)
{
if (requestCode == GALLERY_PICTURE)
除非 FILECHOOSER_RESULTCODE 和 GALLERY_PICTURE 是相同的整数，否则语句将永远不会通过.
unless FILECHOOSER_RESULTCODE and GALLERY_PICTURE are the same ints then statement will never pass.
