安卓仿微信朋友圈拍照获取照片，压缩照片，显示上传，可以预览根据手势放大与缩小图片

最近项目要求做一个仿微信朋友圈拍照获取照片显示上传，要对图片进行压缩处理，防止OOM，废话不多说，下面进行拍照功能实现：

实现效果如图：

1.选择界面：

    

预览界面（可以根据手势放大缩小）：

已经封装成一个lib包，直接添加项目依赖就能使用：

下载依赖包地址源码：

https://download.csdn.net/download/zqr772791008/10300742

项目大概长这样：

对类的说明：

1. Constatnt：拍照功能的一些基础参数配置
2. IMakePic：图片压缩获取成功以后的回调接口；
3. MakePhotoAdapter：九宫格适配器
4. PhotoFileUtils：照片文件处理器
5. TakePhotoUtil：拍照的工具类
   
6. imagezoom： 根据手势放大与缩小的包

开始之前记得添加权限：

android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
android:name="android.permission.WAKE_LOCK" />

android:name="android.permission.CAMERA"/>


            android:name="com.zoesoft.mobile.imagezoom.activity.ImagePagerActivity"
        >
    

使用方法例子：

package com.example.administrator.myapplication.photo;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.util.Log;

import com.example.administrator.myapplication.R;

import java.util.ArrayList;

public class photoActivity extends AppCompatActivity implements IMakePic {

    RecyclerView mRecyclerView;

    MakePhotoAdapter mMakePicAdapter;

    ArrayList photoInfos = new ArrayList<>();

    TakePhotoUtil takePhotoUtil;

    // 相机取图
    private static final int CAMERA_WITH_DATA = 1000;
    private String imageUrl;
    private Uri imageUri;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_photo);

        mRecyclerView = (RecyclerView) findViewById(R.id.rv_addphoto);

        takePhotoUtil = new TakePhotoUtil(CAMERA_WITH_DATA,this,this);
        //图片列表
        GridLayoutManager mLayoutManager = new GridLayoutManager(this, 3);
        mRecyclerView.setLayoutManager(mLayoutManager);


        mMakePicAdapter = new MakePhotoAdapter(this, photoInfos, this, Constatnt.EDIT);
        mMakePicAdapter.setMaxCount(9);
        mRecyclerView.setAdapter(mMakePicAdapter);

    }



    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

            if (requestCode == CAMERA_WITH_DATA && resultCode == RESULT_OK ) {
//                luban();
                takePhotoUtil.luBanCompress();//压缩图片
            }

    }








    @Override
    public void takePic() {
//        doTakePhoto();
        takePhotoUtil.doTakePhoto();//开启相机
}

    @Override
    public void onImageUpload(String url) {
        photoInfos.add(url);
        Log.e("photoInfos的大小",""+photoInfos.size());
        mMakePicAdapter.setDataList(photoInfos);
    }


}

关键代码：

1.Constatnt类：

package com.example.administrator.myapplication.photo;



public class Constatnt {
    
    /**
     * 图片显示的最大数量
     */
    public static final int MAX_COUNT = 9;
    
    /**
     * 是否显示增加按钮
     */
    public static final int ITEM_ADD = 0;
    
    public static final int ITEM_CONTENT = 1;
    
    /**
     * 显示图片
     */
    public static final int SHOW = 10000;
    
    /**
     * 编辑图片
     */
    public static final int EDIT = 20000;
    
}

2.IMakePic：

package com.example.administrator.myapplication.photo;


 
public interface IMakePic {



    /**
     * 拍照片
     */
    void takePic();


    /**
     * 图片压缩获取成功以后的回调接口
     */
        void onImageUpload(String url);
}

3.MakePhotoAdapter：

package com.example.administrator.myapplication.photo;

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

    private IMakePic mMakePic = null;

    /**
     * 显示还是编辑
     */
    private int type = Constatnt.SHOW;

    /**
     * 图片选取的最大数量，当达到最大数量是，不显示增加按钮
     */
    private int maxCount = Constatnt.MAX_COUNT;

    public int getType() {
        return type;
    }

    public void setType(int type) {
        this.type = type;
    }

    public int getMaxCount() {
        return maxCount;
    }

    public void setMaxCount(int maxCount) {
        this.maxCount = maxCount;
    }

    public MakePhotoAdapter(Context context, List photoInfoList, IMakePic makePic) {
        this(context, photoInfoList, makePic, Constatnt.EDIT);
    }

    public MakePhotoAdapter(Context context, List photoInfoList, IMakePic makePic, int type) {
        mContext = context;
        mPhotoInfoList = photoInfoList;
        mMakePic = makePic;
        this.type = type;
        mInflater = LayoutInflater.from(mContext);
    }

    /**
     * 判断是否需要显示一个增加按钮，当达到最大数量是不显示增加按钮
     * @return
     */
    @Override
    public int getItemCount() {
        if (getType() == Constatnt.SHOW) {
            return mPhotoInfoList.size();
        }
        else {
            int num = mPhotoInfoList.size();
            return num == getMaxCount() ? getMaxCount() : ++num;
        }
    }

    /**
     * 判断选择哪种布局，一种是显示布局，一种是增加布局（有删除按钮）
     * @param position
     * @return
     */
    @Override
    public int getItemViewType(int position) {
        if (getType() == Constatnt.SHOW) {
            return Constatnt.ITEM_CONTENT;
        }
        else {
            if (position == mPhotoInfoList.size()) {
                return Constatnt.ITEM_ADD;
            }
            return Constatnt.ITEM_CONTENT;
        }
    }

    /**
     * 返回列表数据
     *
     * @return
     */
    public List getDataList() {
        return this.mPhotoInfoList;
    }

     * @param dataList
     */

        notifyDataSetChanged();
    }



    @Override
