startActivityForResult不在片段工作 [英] startActivityForResult is not working in Fragment

问题描述

我目前正在与片段工作。我想从挑选的画廊和放图像;它显示到片段类。但这里startActivityForResult（）不工作片段

我的片段类

 按钮的LoadImage =（按钮）view.findViewById（R.id.loadButton）;
    loadimage.setOnClickListener（新OnClickListener（）{        @覆盖
        公共无效的onClick（视图v）{
            // TODO自动生成方法存根
            意图I =新意图（Intent.ACTION_PICK，android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI）;
             startActivityForResult（ⅰ，RESULT_LOAD_IMAGE）;
        }
    }）;
@覆盖
公共无效的onActivityResult（INT申请code，INT结果code，意图数据）{
    super.onActivityResult（要求code，结果code，数据）;    如果（要求code == RESULT_LOAD_IMAGE＆放大器;＆安培;结果code == RESULT_OK＆放大器;＆安培;！NULL =数据）{
        乌里selectedImage = data.getData（）;
        的String [] = filePathColumn {MediaStore.Images.Media.DATA};        光标光标= getActivity（）。getContentResolver（）查询（selectedImage，
                filePathColumn，NULL，NULL，NULL）;
        cursor.moveToFirst（）;        INT参数：columnIndex = cursor.getColumnIndex（filePathColumn [0]）;
        字符串picturePath = cursor.getString（参数：columnIndex）;
        cursor.close（）;
        imgview.setImageBitmap（BitmapFactory.de codeFILE（picturePath））;    }    }
 

解决方案

在活动类：

  @覆盖
公共无效的onActivityResult（INT申请code，INT结果code，意图数据）{
    super.onActivityResult（要求code，结果code，数据）;
}
 

在片段：

  @覆盖
公共无效的onActivityResult（INT申请code，INT结果code，意图数据）{
    //处理活动的结果在这里
}
 

从片段开始结果活动：

 意向意图=新意图（android.provider.MediaStore.ACTION_IM​​AGE_CAPTURE）;
startActivityForResult（意向，1）;
 

I am currently working with with Fragment. I want to pick Image from gallery & display it onTo fragment class. But here startActivityForResult() is not working in Fragment.

My fragment class

Button loadimage=(Button) view.findViewById(R.id.loadButton);
    loadimage.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
             startActivityForResult(i, RESULT_LOAD_IMAGE);
        }
    });
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getActivity().getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();
        imgview.setImageBitmap(BitmapFactory.decodeFile(picturePath));

    }

    }

解决方案

In Activity class:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
    super.onActivityResult(requestCode,resultCode,data);
}

In Fragment :

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
    //  Handle activity result here  
}

start activity for result from fragment:

Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 1);
