基于Loader的宫格图片选择器库

图片选择器

准备工作

1.获取依赖

project的build.gradle

allprojects {
    repositories {
        ......       
        maven { url "https://jitpack.io" } 
        maven { url  "https://dl.bintray.com/yongdongji/android" }
    }
}

app的build.gradle

 
implementation ('www.weimu.io:imagepicker:{latest}@aar'){ transitive = true }

//以下为此aar所依赖的第三方
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.github.bumptech.glide:glide:4.6.1'
annotationProcessor 'com.github.bumptech.glide:compiler:4.6.1'
implementation 'com.github.chrisbanes:PhotoView:2.0.0'
implementation 'com.isseiaoki:simplecropview:1.1.7@aar'
implementation 'top.zibin:Luban:1.1.3'

2.增加权限

<!-- 相机权限 -->
<uses-permission android:name="android.permission.CAMERA" />
<!-- 存储权限 -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

3.增加FileProvider【适配7.0】

注意：此处的android:resource="@xml/filepaths"自己谷歌或直接获取demo文件

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="${applicationId}.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/filepaths" />
</provider>

用法

1.1.打开图库

ImagePicker.getInstance().pickImage(activity);

多参数调用

/**
 * @param activity
 * @param maxSelectNum 最大选择图片数          default=9
 * @param mode 图库模式【单选】【多选】         default=ImageSelectorActivity.MODE_MULTIPLE
 * @param enableCamera 是否启用摄像头          default=true
 * @param enablePreview 是否打开预览           default=true
 * @param enableCrop 是否进行裁剪【单选可用】   default=false
 */
ImagePicker.getInstance().pickImage(activity, 9, ImageSelectorActivity.MODE_MULTIPLE, true, true, false);

1.2.直接拍张

ImagePicker.getInstance().takePhoto(activity);

多参数调用

/**
 * @param activity
 * @param enableCrop 是否启用裁剪 default=false
 */
ImagePicker.getInstance().takePhoto(activity,false);

2.接收结果信息

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(resultCode == RESULT_OK && requestCode == ImageSelectorActivity.REQUEST_IMAGE){
        ArrayList<String> images = (ArrayList<String>) data.getSerializableExtra(ImageSelectorActivity.REQUEST_OUTPUT);
        // do something
    }
}
