涉及圆角与图片web加载，使用fresco

1. 在build.gradle添加依赖

    compile 'com.facebook.fresco:fresco:0.14.1'
    compile 'com.facebook.fresco:animated-gif:0.14.1'

2. 在使用imageview的地方使用自定义组件

  <com.facebook.drawee.view.SimpleDraweeView
            android:id="@+id/user_image"
            android:layout_width="80dp"
            android:layout_height="80dp"
            android:layout_marginBottom="10dp"
            android:layout_marginLeft="15dp"
            android:layout_marginTop="10dp"
            android:scaleType="fitXY"
            fresco:roundedCornerRadius="5dp"
            fresco:roundingBorderWidth="1dp"
            />

3. 调用,传入uri即可

public ImageView userImage;

userImage = (ImageView) view.findViewById(R.id.user_image);
userImage.setImageURI(Uri.parse(userMessage.getAvatar()));

本地更换图片

点击图片更换

1. 设置点击事件

        userImage.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                ((Activity) context).startActivityForResult(intent, 1);
            }
        });

2. activity中回调

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        //获取图片路径
        if (requestCode == 1 && resultCode == Activity.RESULT_OK && data != null) {
            Uri selectedImage = data.getData();
            String[] filePathColumns = {MediaStore.Images.Media.DATA};
            Cursor c = getContentResolver().query(selectedImage, filePathColumns, null, null, null);
            c.moveToFirst();
            int columnIndex = c.getColumnIndex(filePathColumns[0]);
            String imagePath = c.getString(columnIndex);  //文件路径
            showImage(imagePath);
            c.close();
        }
    }

3. 使用ok-go文件上传

    private void showImage(String imagePath) {
        OkGo.post(Constants.IMAGEHOSTIP+"/upload")//
                .tag(this)//
                .isMultipart(true)       // 强制使用 multipart/form-data 表单上传（只是演示，不需要的话不要设置。默认就是false）
                .params("myFile", new File(imagePath))   // 可以添加文件上传
                .execute(new StringCallback() {
                    @Override
                    public void onSuccess(String s, Call call, Response response) {
                        //上传成功
                        //获取图片控件修改图片
                        FragmentManager fm = getSupportFragmentManager();
                        ContentFragment fragmentByTag = (ContentFragment) fm.findFragmentByTag(MAIN_CONTENT_TAG);
                        ContentUserPager basePager = (ContentUserPager) fragmentByTag.basePagers.get(1);
                        basePager.userMessage.setAvatar(s.substring(8,s.length()-2));
                        basePager.userImage.setImageURI(Uri.parse(s.substring(8,s.length()-2)));
                        Toast.makeText(MainActivity.this,"图片更换成功，请保存",Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void upProgress(long currentSize, long totalSize, float progress, long networkSpeed) {
                        super.upProgress(currentSize, totalSize, progress, networkSpeed);
                    }

                    @Override
                    public void onError(Call call, Response response, Exception e) {
                        super.onError(call, response, e);
                        Toast.makeText(MainActivity.this,"图片更换失败",Toast.LENGTH_SHORT).show();
                    }
                });

    }
