android批量图片上传_安卓如何选择多张图片_本地多图片选择Demo

调用系统图库的代码，但是调用之后，点击一张照片图库就会关闭，并将图片数据返回

如果要做一个照片批量上传功能的话，一张一张去选择照片的话，用户绝对会抓狂

先给大家贴一下单选的代码

Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
intent.addCategory(Intent.CATEGORY_OPENABLE); 
intent.setType("image/*"); 
startActivityForResult(intent, CHOOSE_PHOTO); 

调用系统图库，如何一次性选择多张图片，或者直接选择一个图片文件夹啊

经过我查阅资料后发现系统图库是不支持图片多选的（也许是我没有查到吧）

所以就只能挂接选择图片文件夹来实现我们的需求咯

大致实现过程是将本地所有有图片的文件夹先找出来、然后让用户去选择到底是进入那个文件夹、以下是部分代码

public List<FileTraversal> LocalImgFileList(){
    List<FileTraversal> data=new ArrayList<FileTraversal>();
    String filename="";
    List<String> allimglist=listAlldir();
    List<String> retulist=new ArrayList<String>();
    if (allimglist!=null) {
        Set set = new TreeSet();
        String []str;
        for (int i = 0; i < allimglist.size(); i++) {
            retulist.add(getfileinfo(allimglist.get(i)));
        }
        for (int i = 0; i < retulist.size(); i++) {
            set.add(retulist.get(i));
        }
        str= (String[]) set.toArray(new String[0]);
        for (int i = 0; i < str.length; i++) {
            filename=str[i];
            FileTraversal ftl= new FileTraversal();
            ftl.filename=filename;
            data.add(ftl);
        }
        
        for (int i = 0; i < data.size(); i++) {
            for (int j = 0; j < allimglist.size(); j++) {
                if (data.get(i).filename.equals(getfileinfo(allimglist.get(j)))) {
                    data.get(i).filecontent.add(allimglist.get(j));
                }
            }
        }
    }
    return data;
}

然后当用户点击以item的时候、进入另外一个画面、展示该文件夹下面所有图片、以下是部分代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.photogrally);
    
    imgGridView=(GridView) findViewById(R.id.gridView1);
    bundle= getIntent().getExtras();
    fileTraversal=bundle.getParcelable("data");
    imgsAdapter=new ImgsAdapter(this, fileTraversal.filecontent,onItemClickClass);
    imgGridView.setAdapter(imgsAdapter);
    select_layout=(LinearLayout) findViewById(R.id.selected_image_layout);
    relativeLayout2=(RelativeLayout) findViewById(R.id.relativeLayout2);
    choise_button=(Button) findViewById(R.id.button3);
    hashImage=new HashMap<Integer, ImageView>();
    filelist=new ArrayList<String>();
//        imgGridView.setOnItemClickListener(this);
    util=new Util(this);
}

class BottomImgIcon implements OnItemClickListener{
    
    int index;
    public BottomImgIcon(int index) {
        this.index=index;
    }
    
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
            long arg3) {
        
    }
}

@SuppressLint("NewApi")
public ImageView iconImage(String filepath,int index,CheckBox checkBox) 
                        throws FileNotFoundException{
    LinearLayout.LayoutParams params=new LayoutParams(relativeLayout2.
    getMeasuredHeight()-10, relativeLayout2.getMeasuredHeight()-10);
    ImageView imageView=new ImageView(this);
    imageView.setLayoutParams(params);
    imageView.setBackgroundResource(R.drawable.imgbg);
    float alpha=100;
    imageView.setAlpha(alpha);
    util.imgExcute(imageView, imgCallBack, filepath);
    imageView.setOnClickListener(new ImgOnclick(filepath,checkBox));
    return imageView;
}

ImgCallBack imgCallBack=new ImgCallBack() {
    @Override
    public void resultImgCall(ImageView imageView, Bitmap bitmap) {
        imageView.setImageBitmap(bitmap);
    }
};

class ImgOnclick implements OnClickListener{
    String filepath;
    CheckBox checkBox;
    public ImgOnclick(String filepath,CheckBox checkBox) {
        this.filepath=filepath;
        this.checkBox=checkBox;
    }
    @Override
    public void onClick(View arg0) {
        checkBox.setChecked(false);
        select_layout.removeView(arg0);
        choise_button.setText("已选择("+select_layout.getChildCount()+")张");
        filelist.remove(filepath);
    }
}
