从gallry获取图像中片段的ImageView设置？ [英] Get image from gallry to set in imageview in fragment?

问题描述

如何从GALLARY获取图像中片段的ImageView设置？在fragment..this的onActivityResult不叫code I片段中写道：

  img_user.setOnClickListener（新View.OnClickListener（）{
            @覆盖
        公共无效的onClick（视图v）{            意图I =新意图（Intent.ACTION_PICK，
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI）;
            startActivityForResult（ⅰ，RESULT_LOAD_IMAGE）;
        }
    }）;
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（数据！= NULL）{
            乌里selectedImage = data.getData（）;
            的String [] = filePathColumn {MediaStore.Images.Media.DATA};
            光标光标=的getContext（）。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）;
            img_user.setImageBitmap（BitmapFactory.de codeFILE（picturePath））;
            cursor.close`enter code here`（）;
        }其他{
            Toast.makeText（getActivity（），再试一次！，Toast.LENGTH_SHORT）
                    。显示（）;
        }    }
 

解决方案

您可以通过这种方式做到这一点....你的主要活动

  @覆盖
    保护无效的onActivityResult（INT申请code，INT结果code，意图数据）{
       //调用super
       super.onActivityResult（要求code，结果code，数据）;
     }
 

和您的片段里面

 意向书I =新意图（Intent.ACTION_PICK，android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI）;
                // ******** code作物图像
                i.putExtra（裁剪，真）;
                i.putExtra（aspectX，100）;
                i.putExtra（aspectY，100）;
                i.putExtra（outputX，256）;
                i.putExtra（outputY，356）;                尝试{                    i.putExtra（回归数据，真正的）;
                    startActivityForResult（
                            Intent.createChooser（ⅰ，选择图像），0）;
                }赶上（ActivityNotFoundException前）{
                    ex.printStackTrace（）;
                }
 

和

  @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 == 0安培;＆安培;结果code == Activity.RESULT_OK）{
            尝试{
                捆绑包= data.getExtras（）;
                位图位图= bundle.getParcelable（数据）;
                img_user.setImageBitmap（位图）;
            }赶上（例外五）{
                e.printStackTrace（）;
            }
        }
    }
 

工作非常适合我。

How to get image from gallary to set in Imageview in fragment ? onActivityResult not called in fragment..this the code i wrote in fragment

img_user.setOnClickListener(new View.OnClickListener() {
            @Override
        public void onClick(View v) {

            Intent i = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(i, RESULT_LOAD_IMAGE);


        }
    });


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


        if (data != null) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContext().getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);

            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            img_user.setImageBitmap(BitmapFactory.decodeFile(picturePath));
            cursor.close`enter code here`();
        } else {
            Toast.makeText(getActivity(), "Try Again!!", Toast.LENGTH_SHORT)
                    .show();
        }

    }

解决方案

You can do this in this way....in your main activity

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

and inside your fragment

 Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                // ******** code for crop image
                i.putExtra("crop", "true");
                i.putExtra("aspectX", 100);
                i.putExtra("aspectY", 100);
                i.putExtra("outputX", 256);
                i.putExtra("outputY", 356);

                try {

                    i.putExtra("return-data", true);
                    startActivityForResult(
                            Intent.createChooser(i, "Select Picture"), 0);
                }catch (ActivityNotFoundException ex){
                    ex.printStackTrace();
                }

and

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if(requestCode==0 && resultCode == Activity.RESULT_OK){
            try {
                Bundle bundle = data.getExtras();
                Bitmap bitmap = bundle.getParcelable("data");
                img_user.setImageBitmap(bitmap);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

Works perfect for me
