TakePhoto实现拍照得到图片和从相册得到图片

在学郭霖大神的第一行代码的时候,学到利用相机拍照和从本地相册取照片的那一小节的时候,代码写出来但是出了很多问题,APP老是崩溃,一番百度最终还是没有找到解决办法

无奈只能用别人现成的轮子了,然后就发现了这个TakePhoto框架,很多人都推荐用这个,所以写下这个博客来记录一下这个框架的基本使用

TakePhoto是一个很优秀的关于图片的一些处理的第三方框架

GitHub地址如下:https://github.com/crazycodeboy/TakePhoto

配置的办法很简单,在工程目录的APP目录下的build.gradle里面的dependencies标签加入依赖即可

compile 'com.jph.takephoto:takephoto_library:4.0.3'

官方的最新版本是4.1.0,但我这边加入4.1.0的依赖会报错,然后我试了一下4.0.3的是可以的,所以就直接用4.0.3了

大致实现过程就是实现TakePhoto.TakeResultListener, InvokeListener接口

然后重写几个方法就行,方法体里面的内容根据自己的项目需要进行编写

                            case 0:
                                //拍照并裁剪
                                takePhoto.onPickFromCaptureWithCrop(uri, cropOptions);
                                break;
                            case 1:
                                //从照片选择并裁剪

                                break;
                            default:
                                break;
                        }
                    }
                });
                builder.show();
            }
        });
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        getTakePhoto().onActivityResult(requestCode, resultCode, data);
        super.onActivityResult(requestCode, resultCode, data);
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        getTakePhoto().onSaveInstanceState(outState);
        super.onSaveInstanceState(outState);
    }

    @Override

        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        //以下代码为处理Android6.0、7.0动态权限所需
        PermissionManager.TPermissionType type = PermissionManager.onRequestPermissionsResult(requestCode, permissions, grantResults);
        PermissionManager.handlePermissionsResult(this, type, invokeParam, this);
    }

    @Override
    public PermissionManager.TPermissionType invoke(InvokeParam invokeParam) {
        PermissionManager.TPermissionType type = PermissionManager.checkPermission(TContextWrap.of(this), invokeParam.getMethod());
        if (PermissionManager.TPermissionType.WAIT.equals(type)) {
            this.invokeParam = invokeParam;
        }
        return type;
    }

    public TakePhoto getTakePhoto() {
        //获得TakePhoto实例
        if (takePhoto == null) {
            takePhoto = (TakePhoto) TakePhotoInvocationHandler.of(this).bind(new TakePhotoImpl(this, this));
        }
        //设置压缩规则，最大500kb
        takePhoto.onEnableCompress(new CompressConfig.Builder().setMaxSize(500 * 1024).create(), true);
        return takePhoto;
    }

    @Override
    public void takeSuccess(final TResult result) {
        //成功取得照片
        test = new File(result.getImage().getOriginalPath());
        editor = sharedPreferences.edit();
        editor.putString("image_path",result.getImage().getOriginalPath());
        editor.commit();
        if(test.exists()){
            bitmap = BitmapFactory.decodeFile(result.getImage().getOriginalPath());
            headSculpture.setImageBitmap(bitmap);
        }
    }

    @Override
    public void takeFail(TResult result, String msg) {
        //取得失败
        Toast.makeText(Setting.this,"设置失败",Toast.LENGTH_SHORT).show();
    }

    @Override
    public void takeCancel() {
        //取消
    }

}

取出照片还有一些其他操作可能需要看一下里面TResult和TImage这两个类

效果如下
