# PhotoPicker [![](https://jitpack.io/v/PengHaiZhuo/PhotoPicker.svg)](https://jitpack.io/#PengHaiZhuo/PhotoPicker)
图片选择器

#### 工程目录下gradle文件添加jitpack依赖：

```
allprojects {
    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
        maven { url "https://jitpack.io" }
    }
}
```
#### 添加权限AndroidManifest.xml

```
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
```

#### sample使用了第三方库九宫格，添加依赖如下（本库也支持单选，请根据自己情况而定）

```
dependencies {
	//此处省略...
	
    //9宫格的图片选择
    implementation 'com.jaeger.ninegridimageview:library:1.1.1'
	//本地库依赖
    //implementation project(':photopicker')
    //远程依赖
    implementation 'com.github.PengHaiZhuo:PhotoPicker:1.0.3'
}
```

#### 使用

```
/**
 * 当前选择的图片路径
 */
private ArrayList<String> imagePathsList = new ArrayList<>();
/**
 * 允许上传照片最大数量
 */
private static final int INT_MAXSIZE_IMG = 9;

/**
 * 跳转到图片选择器
 * @param position：预览图片需要传当前图片位置，配合imagePathsList使用
 * @param isPick 是否是添加图片
 */
private void toPickPhoto(int position,boolean isPick){
    if (isPick) {
        PickImageIntent intent = new PickImageIntent(mContext);
        //设置为多选模式
        intent.setSelectModel(SelectMode.MULTI);
        // 是否拍照
        intent.setIsShowCamera(true);
        //设置最多选择照片数量
        if (imagePathsList.size() > 0 && imagePathsList.size() < (INT_MAXSIZE_IMG + 1)) {
            // 最多选择照片数量
            intent.setSelectedCount(INT_MAXSIZE_IMG + 1 - imagePathsList.size());
        } else {
            intent.setSelectedCount(0);
        }
        /*// 已选中的照片地址，用于回显选中状态
        intent.setSelectedPaths(imagePathsList);*/
        startActivityForResult(intent, REQUEST_CAMERA_CODE);
    } else {
    	//预览图片
        PreViewImageIntent intent = new PreViewImageIntent(mContext);
        intent.setCurrentItem(position);
        intent.setPhotoPaths(imagePathsList);
        startActivityForResult(intent, REQUEST_PREVIEW_CODE);
    }
}
```

#### 重写onActivityResult方法，获取选择的照片路径列表

```
private static final int REQUEST_CAMERA_CODE = 10;
   private static final int REQUEST_PREVIEW_CODE = 20;
    @Override
   protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
       super.onActivityResult(requestCode, resultCode, data);
       if (resultCode==RESULT_OK){
           switch (requestCode) {
               case REQUEST_CAMERA_CODE:
                   if (data != null) {
                       ArrayList<String> list = data.getStringArrayListExtra(ImagePickerConstract.EXTRA_RESULT);
                       //todo 显示图片
                   }
                   break;
               case REQUEST_PREVIEW_CODE:
                   if (data != null) {
                       ArrayList<String> ListExtra = data.getStringArrayListExtra(ImagePickerConstract.EXTRA_RESULT);
                       if (imagePathsList != null) {
                           imagePathsList.clear();
                       }
                       imagePathsList.addAll(ListExtra);
                       //todo 预览里可能删除了图片，所以需要更新显示的图片
                   }
                   break;
           }
       }
   }
```
