TakePhoto實現拍照得到圖片和從相冊得到圖片

在學郭霖大神的第一行代碼的時候,學到利用相機拍照和從本地相冊取照片的那一小節的時候,代碼寫出來但是出了很多問題,APP老是崩潰,一番百度最終還是沒有找到解決辦法

無奈只能用別人現成的輪子了,然后就發現了這個TakePhoto框架,很多人都推薦用這個,所以寫下這個博客來記錄一下這個框架的基本使用

TakePhoto是一個很優秀的關於圖片的一些處理的第三方框架

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

配置的辦法很簡單,在工程目錄的APP目錄下的build.gradle里面的dependencies標簽加入依賴即可

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

官方的最新版本是4.1.0,但我這邊加入4.1.0的依賴會報錯,然后我試了一下4.0.3的是可以的,所以就直接用4.0.3了

大致實現過程就是實現TakePhoto.TakeResultListener, InvokeListener接口

然后重寫幾個方法就行,方法體里面的內容根據自己的項目需要進行編寫

                            case 0:
                                //拍照並裁剪
                                takePhoto.onPickFromCaptureWithCrop(uri, cropOptions);
                                break;
                            case 1:
                                //從照片選擇並裁剪
                                takePhoto.onPickFromGalleryWithCrop(uri, cropOptions);
                                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
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        //以下代碼為處理Android6.0、7.0動態權限所需
        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() {
        //獲得TakePhoto實例
        if (takePhoto == null) {
            takePhoto = (TakePhoto) TakePhotoInvocationHandler.of(this).bind(new TakePhotoImpl(this, this));
        }
        //設置壓縮規則，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) {
        //取得失敗
        Toast.makeText(Setting.this,"設置失敗",Toast.LENGTH_SHORT).show();
    }

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




}

取出照片還有一些其他操作可能需要看一下里面TResult和TImage這兩個類

效果如下
