CropView

介绍

android image cropping library. Support from camera, gallery, image rotate.

Android的图像裁剪库。支持从相机，图库选择图片，裁切时图像旋转。

使用

• 导入lib-cropview并在AndroidManifest.xml中添加Activity

  <activity android:name="com.jeanboy.cropview.cropper.CropActivity"
          android:theme="@style/AppTheme.NoActionBar"/>

• 实现CropperHandler并实现方法

  @Override
  public Activity getActivity() {
      return this;
  }
  
  @Override
  public CropperParams getParams() {
      //配置裁切框比例
      return new CropperParams(1, 1);
      //不约束裁切比例
      // return new CropperParams(0, 0);
  }
  
  @Override
  public void onCropped(Uri uri) {
      Log.d("=====onCropped======", "======裁切成功=======" + uri);
  }
  
  @Override
  public void onCropCancel() {
      Log.d("=====onCropCancel====", "======裁切取消=====");
  }
  
  @Override
  public void onCropFailed(String msg) {
      Log.d("=====onCropFailed===", "=======裁切失败======" + msg);
  }

• 初始化CropperManager

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        CropperManager.getInstance().build(this);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        CropperManager.getInstance().handlerResult(requestCode, resultCode, data);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        CropperManager.getInstance().destroy();
    }

• 调用操作

  CropperManager.getInstance().pickFromCamera();//拍照裁切
  CropperManager.getInstance().pickFromGallery();//图库选择裁切

  注意事项

  CropActivity不需要ActionBar

  <style name="AppTheme.NoActionBar" parent="AppTheme">
  <!-- 关闭ActionBar -->
  <item name="windowActionBar">false</item>
  <!-- 隐藏title -->
  <item name="windowNoTitle">true</item>
  </style>
