refactor the repository, easy to use with gradle import. [![]( Modified by Swiftyhttps://jitpack.io/v/SwiftyWang/android-drag-square.svg)](https://jitpack.io/#SwiftyWang/android-drag-square)
Add it in your root build.gradle at the end of repositories: How to use
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
compile 'com.github.SwiftyWang.android-drag-square:android-crop:1.2.3'
}
```java DraggableSquareView dragSquare = (DraggableSquareView) findViewById(R.id.drag_square); contentText = (TextView) findViewById(R.id.contentText); draggablePresent = new DraggablePresentImpl(fragment, dragSquare); draggablePresent = new DraggablePresentImpl(activity, dragSquare); ``` get DraggablePresenter
need pass activity callback to DraggablePresentImpl:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent result) {
draggablePresent.onActivityResult(requestCode, resultCode, result);
}
Customer dialog must extends ActionDialog.class ```java draggablePresent.setCustomActionDialog(new MyActionDialog(Context)); ``` Set customer dialog
```java dragSquare.setImageChangesListener(imageChangesListener); listen image changes
public interface ImageChangesListener {
void onImageAdded(String uri, int index);
void onImageEdited(String uri, int index);
void onImageDeleted(String uri, int index);
}
<h3>All public apis</h3>
```java
SparseArray<String> getImageUrls();
void setImages(String... imageUrls);
void setCustomActionDialog(ActionDialog actionDialog);

edit personal data which enables users to drag and rank image order
编辑个人资料,图片可拖拽排序。有点像可拖拽的gridView,但是会更流畅。
这个demo是探探的个人资料编辑页面,受网上一位朋友的委托,该库模仿了其拖动效果。
探探的安卓工程师,应该特别牛逼吧。因为最初时,这种拖拽效果真的无从下手。反编译探探的源代码,发现它做了很严肃的混淆处理。然后用Hierarchy Viewer看了View的层级,这才有了一点点的思路。
在代码撰写的过程中,我也踩了不少坑。细看代码深处,或许你会有一丝丝的收获吧。
当然,在最初的最初,我搜了不少的draggable gridview的仓库,可惜用起来的时候发现不够流畅、不够灵活。
