Android-分享收集到的UCrop工具類

圖片來源網(wǎng)絡，入侵必刪

在日常的Android開發(fā)當中，我們圖片裁剪的時候，大部分情況，我們都會使用UCrop開源庫來做裁剪。這里分享一個從網(wǎng)上收集到的UCrop相關的工具類，我個人感覺提高了開發(fā)效率。

這是整個工具類的代碼，需要的小伙伴可以直接復制到項目當中使用。封裝方法說明請看下面。

打開相機

public static void cropFromCamera(Activity context)

打開相冊

public static void cropFromGallery(Activity context)

從圖庫選擇頭像

public static void cropAvatarFromGallery(Activity context)

拍照裁剪頭像

public static void cropAvatarFromCamera(Activity context)

自定義方法

public static void cropFromGallery(Activity context,CropConfig config,int type)
public static void cropFromCamera(Activity context,CropConfig config,int type)

選擇回調(diào)

public static void onActivityResult( int requestCode, int resultCode, Intent data,Activity context, CropHandler cropHandler)

選調(diào)接口

public interface CropHandler {
   void handleCropResult(Uri uri,int tag);
   void handleCropError(Intent data);
}

UCrop一定要導入

implementation 'com.github.yalantis:ucrop:2.2.6'

清單注冊裁剪界面

<activity
    android:name="com.yalantis.ucrop.UCropActivity"
    android:screenOrientation="portrait"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>
