Android 自定义拍照+剪切+相册选择一张或多张图片

一、集成

在build中集成框架位置如下图：

 //图片框架
    implementation 'com.github.bumptech.glide:glide:4.9.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
    //导入相册多图片选择库
    implementation 'com.github.donkingliang:ImageSelector:2.1.1'

二、实现效果

 主页面MainActivity的布局XML文件代码activity_main.xml：

MainActivity代码：

package com.zdmtech.photoalbumimgdemo;

import android.view.View;
import android.widget.Button;

import com.zdmtech.photoalbumimgdemo.activity.AlbumActivity;
import com.zdmtech.photoalbumimgdemo.activity.PhotoActivity;
import com.zdmtech.photoalbumimgdemo.activity.PhotoCropActivity;
import com.zdmtech.photoalbumimgdemo.activity.autoCamera.AutoCameraActivity;
import com.zdmtech.photoalbumimgdemo.base.BaseActivity;
import com.zdmtech.photoalbumimgdemo.camera2.PhotoImageSelectActivity;

/**
 * 自定义拍照+剪切+相册选择一张图片
 * */
public class MainActivity extends BaseActivity implements View.OnClickListener {
    private Button btn_photo, btn_album, btn_photo_crop;
    private Button btn_albumMore ;

    @Override
    public int intiLayout() {
        return R.layout.activity_main;
    }

    @Override
    public void initView() {
        btn_photo = findViewById(R.id.btn_photo);
        btn_photo_crop = findViewById(R.id.btn_photo_crop);
        btn_album = findViewById(R.id.btn_album);
        btn_albumMore = findViewById(R.id.btn_albumMore);
    }

    @Override
    public void initData() {
        btn_photo.setOnClickListener(this);
        btn_photo_crop.setOnClickListener(this);
        btn_album.setOnClickListener(this);
        btn_albumMore.setOnClickListener(this);
    }


    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn_photo: //拍照
                goToNextUI(PhotoActivity.class, false, null);
                break;
            case R.id.btn_photo_crop: //拍照+裁剪
                goToNextUI(PhotoCropActivity.class, false, null);
                break;
            case R.id.btn_album: //相册
                goToNextUI(AlbumActivity.class, false, null);
                break;
            case R.id.btn_albumMore: //相册自定义(多张)
                goToNextUI(PhotoImageSelectActivity.class, false, null);
                break;
            default:
                break;
        }
    }

}

    }

}

        其中实现公共的一些方法，比如：跳转到下一个页面、跳转下一个页面并带回返回值、设置状态栏、Toast提示、动态请求权限方法、删除文件及文件夹等等。

        当然，这里还有许多的类以及工具类，比如拍照页面、相册选择页面等等，具体项目接口如下图：

         由于代码内容比较多，小伙伴们可以点击此项目Demo下载代码，可以直接解压在Android Studio中直接运行代码，安装apk使用这些功能了。
