Android 相册回传 相机 （更换头像效果）

我们在开发中，经常会有用户点击头像选择相册或相机更换头像功能。

思路是首先点击头像 弹框选择 相机或者相册 选择图片 裁剪 上传。

所使用的框架MVP+Retrofit+Rxjava

废话少说 直接上代码

//绑定视图
View contentView = LayoutInflater.from(UserMessage.this).inflate(popuwindow_item, null);
View inflate = contentView.inflate(UserMessage.this, R.layout.change_user_head_pic,null);
popWnd = new PopupWindow(inflate);

            popWnd.setContentView(inflate);
            //设置宽高
            popWnd.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
            popWnd.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);

            popWnd.setFocusable(true);
            popWnd.setOutsideTouchable(true);
            popWnd.update();
            popWnd.setBackgroundDrawable(new BitmapDrawable());
            //获取资源id
            Button xiangce=inflate.findViewById(R.id.xiangce);
            Button xiangji=inflate.findViewById(R.id.xiangji);
            Button quxiao = inflate.findViewById(R.id.quxiao);

            //设置popuwindow位置
            popWnd.showAtLocation(inflate, Gravity.BOTTOM, 0, 0);

点击头像弹框popularWindow，选择相册 或者相机 亦或者取消，贴出效果图，布局就不放了。

//相册点击事件
xiangce.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
popWnd.dismiss();
//跳转相册
Intent intent1 = new Intent(Intent.ACTION_PICK, null);
intent1.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, “image/*”);

                    Log.e("===",MediaStore.Images.Media.EXTERNAL_CONTENT_URI+"");
                    List resolveInfos = getPackageManager().queryIntentActivities(intent1
                            , PackageManager.MATCH_DEFAULT_ONLY);
                    //判断用户设备是否有相册
                    if (resolveInfos.size()!=0){
                        startActivityForResult(intent1, 1);
                    }else{
                        Toast.makeText(UserMessage.this,"没有相册",Toast.LENGTH_SHORT).show();
                    }

                }

            });
            //相机点击事件b
            xiangji.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    popWnd.dismiss();
                    //跳转向机
               //     Intent intent2 = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    Intent intent2 = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    intent2.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
                            "head.jpg")));
                    intent2.addCategory("android.intent.category.DEFAULT");
                    List resolveInfos = getPackageManager().queryIntentActivities(intent2
                            , PackageManager.MATCH_DEFAULT_ONLY);
                    //判断用户设备是否有相机
                    if (resolveInfos.size()!=0){
                        startActivityForResult(intent2, 2);//采用ForResult打开
                    }else{
                        ToastUtils.setToastTextview(UserMessage.this,"没有相机");
                        ToastUtils.show();

// Toast.makeText(UserMessage.this,“没有相机”,Toast.LENGTH_SHORT).show();
}

                }
            });

隐式跳转跳转相机相册，此吐司为自定义吐司。

对图片进行裁剪

网络请求

API

@Override
public void UploadUserHeadPicModel(File file, UploadUserHeadPicCallBackData uploadUserHeadPicCallBackData) {

    RequestBody requestBody = RequestBody.create(MediaType.parse("multipart/form-data"), file);

    MultipartBody.Part image = MultipartBody.Part.createFormData("image", file.getName(), requestBody);

    httpUtils.create()
            .getUploadUserHeadPic(image)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Observer() {
                @Override
                public void onSubscribe(Disposable d) {

                }

                @Override
                public void onNext(UploadUserHeadPicBean uploadUserHeadPicBean) {
                    uploadUserHeadPicCallBackData.success(uploadUserHeadPicBean);
                }

                @Override
                public void onError(Throwable e) {

                }

                @Override
                public void onComplete() {

                }
            });

}

RequestBody requestBody = RequestBody.create(MediaType.parse(“multipart/form-data”), file);

    MultipartBody.Part image = MultipartBody.Part.createFormData("image", file.getName(), requestBody);

将File文件转化为MultipartBody.Part 入参

因为本人模拟器没有相机app 所以相机效果不做展示，有兴趣者可自行实现。
