使用南尘的ImagePicker实现仿微信的相册图片选择以及拍照上传
来源：互联网 发布：泰德奥plc编程软件 编辑：程序博客网 时间：2024/05/17 22:52
在记录之前先放上原作的GitHub项目地址：ImagePicker
南尘的框架写得相当不错，我们可以在我们的项目中添加依赖直接使用，但是我在使用的时候发现了一个小bug，就在图片预览的界面选择了图片后，点击返回到所有图片界面时，在预览被选中的图片的CheckBox没有勾上，但是图片是确实已经添加上去了，于是我在他源码的基础上进行了修改，但是我感觉我修改的方法有点low，欢迎大神指点更高级的修改方法。
首先先来说一下这个框架怎么使用，因为这里我要修改源码，所以我直接将源码的module导入到我的工程了，然后在gradle里面加一句：compile project(':imagepicker')
另外，我用了glide框架来加载图片，所以还要加上：compile 'com.github.bumptech.glide:glide:3.7.0'
假设我们添加图片的界面就是MainActivity，所以先上其布局代码activity_main.xml
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="16dp"> <android.support.v7.widget.RecyclerView android:id="@+id/recyclerView" android:layout_width="match_parent" android:layout_height="match_parent" android:choiceMode="singleChoice" android:divider="@null" android:fadingEdge="none" android:listSelector="@android:color/transparent" android:scrollbarStyle="outsideOverlay" app:layoutManager="android.support.v7.widget.GridLayoutManager" app:spanCount="4" tools:listitem="@layout/list_item_image"/></RelativeLayout>其次先新建两个工具类
第一个是图片的加载器，这里我使用的是Glide加载：GlideImageLoader
package demo.yang.com.myimagepicker;import android.app.Activity;import android.net.Uri;import android.widget.ImageView;import com.bumptech.glide.Glide;import com.bumptech.glide.load.engine.DiskCacheStrategy;import com.lzy.imagepicker.loader.ImageLoader;import java.io.File;/** * Created by yxy on 2017/4/10. * email:1084625746@qq.com */public class GlideImageLoader implements ImageLoader { @Override public void displayImage(Activity activity, String path, ImageView imageView, int width, int height) { Glide.with(activity) .load(Uri.fromFile(new File(path))) .error(R.mipmap.f) .placeholder(R.mipmap.f) .diskCacheStrategy(DiskCacheStrategy.ALL) .into(imageView); } @Override public void clearMemoryCache() { }}至于里面的error和placeholder的图片资源大家就自己随便放吧第二个是一个自定义dialog（这个是南尘大神写的）：SelectDialog
package demo.yang.com.myimagepicker;import android.app.Activity;import android.app.Dialog;import android.os.Bundle;import android.text.TextUtils;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.view.ViewGroup.LayoutParams;import android.view.Window;import android.view.WindowManager;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.BaseAdapter;import android.widget.Button;import android.widget.ListView;import android.widget.TextView;import java.util.List;/** * 选择对话框 * * Author: nanchen * Email: liushilin520@foxmail.com * Date: 2017-03-22 11:38 */public class SelectDialog extends Dialog implements OnClickListener,OnItemClickListener { private SelectDialogListener mListener;

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" > <translate android:duration="200" android:fromXDelta="0" android:fromYDelta="1000" android:toXDelta="0" android:toYDelta="0" /></set>photo_dialog_out_anim.xml

只有一列时：dialog_item_bg_only.xml
<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true"><shape> <solid android:color="#CACACB" /> <corners android:bottomLeftRadius="5dp" android:bottomRightRadius="5dp" android:topLeftRadius="5dp" android:topRightRadius="5dp" /> </shape></item> <item><shape> <solid android:color="#EBEBEB" /> <corners android:bottomLeftRadius="5dp" android:bottomRightRadius="5dp" android:topLeftRadius="5dp" android:topRightRadius="5dp" /> </shape></item></selector>多条数据时，第一条数据的背景：select_dialog_item_bg_top.xml

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@mipmap/image_add_sel" android:state_focused="true"/> <item android:drawable="@mipmap/image_add_sel" android:state_pressed="true"/> <item android:drawable="@mipmap/image_add_sel" android:state_selected="true"/> <item android:drawable="@mipmap/image_add_nor"/></selector>下面是这两个图片资源
最后就是MainActivity的代码了
package demo.yang.com.myimagepicker;import android.content.Intent;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 android.view.View;import android.widget.AdapterView;import com.lzy.imagepicker.ImagePicker;import com.lzy.imagepicker.bean.ImageItem;import com.lzy.imagepicker.ui.ImageGridActivity;import com.lzy.imagepicker.ui.ImagePreviewDelActivity;import com.lzy.imagepicker.view.CropImageView;import java.util.ArrayList;import java.util.List;public class MainActivity extends AppCompatActivity implements ImagePickerAdapter.OnRecyclerViewItemClickListener { public static final int IMAGE_ITEM_ADD = -1;//设置是否为添加图片的那个image public static final int REQUEST_CODE_SELECT = 100; public static final int REQUEST_CODE_PREVIEW = 101; private ImagePickerAdapter adapter; private List<ImageItem> selImageList;//当前选择的所有图片 private int maxImgCount = 8;//允许选择的图片最大数量 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initImagePicker(); initWidget(); } private void initImagePicker(){ ImagePicker imagePicker = ImagePicker.getInstance(); imagePicker.setImageLoader(new GlideImageLoader());//设置图片加载器 imagePicker.setShowCamera(true);//显示拍照按钮 imagePicker.setCrop(true);//允许裁剪（单选的时候才有效） imagePicker.setSaveRectangle(true);//是否按矩形区域保存 imagePicker.setSelectLimit(maxImgCount);//选中数量限制 imagePicker.setStyle(CropImageView.Style.RECTANGLE);//裁剪框的形状 imagePicker.setFocusWidth(800);//裁剪框的宽度，单位像素 imagePicker.setFocusHeight(800);//裁剪框的高度，单位像素 imagePicker.setOutPutX(1000);//保存文件的宽度，单位像素 imagePicker.setOutPutY(1000);//保存文件的高度，单位像素 } private void initWidget(){ RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView); selImageList = new ArrayList<>(); adapter = new ImagePickerAdapter(maxImgCount,this,selImageList); adapter.setOnItemClickListener(this); recyclerView.setLayoutManager(new GridLayoutManager(this,4)); recyclerView.setHasFixedSize(true); recyclerView.setAdapter(adapter); } private SelectDialog showDialog(SelectDialog.SelectDialogListener listener,List<String> names){ SelectDialog dialog = new SelectDialog(this,R.style.transparentFrameWindowStyle,listener,names); if (!this.isFinishing()){ dialog.show(); } return dialog; } @Override public void onItemClick(View view, int position) { switch (position){ case IMAGE_ITEM_ADD: List<String> names = new ArrayList<>(); names.add("拍照"); names.add("相册"); showDialog(new SelectDialog.SelectDialogListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { switch (position){ case 0://直接调起相机 //打开选择，本次允许选择的数量 ImagePicker.getInstance().setSelectLimit(maxImgCount - selImageList.size()); Intent intent = new Intent(MainActivity.this, ImageGridActivity.class); intent.putExtra(ImageGridActivity.EXTRAS_TAKE_PICKERS,true); startActivityForResult(intent,REQUEST_CODE_SELECT); break; case 1://打开相册 //打开选择，本次允许选择的数量 ImagePicker.getInstance().setSelectLimit(maxImgCount - selImageList.size()); Intent intent1 = new Intent(MainActivity.this,ImageGridActivity.class); startActivityForResult(intent1,REQUEST_CODE_SELECT); break; default: break; } } },names); break; default: //打开预览 Intent intentPreView = new Intent(this, ImagePreviewDelActivity.class); intentPreView.putExtra(ImagePicker.EXTRA_IMAGE_ITEMS,(ArrayList<ImageItem>)adapter.getImages()); intentPreView.putExtra(ImagePicker.EXTRA_SELECTED_IMAGE_POSITION,position); intentPreView.putExtra(ImagePicker.EXTRA_FROM_ITEMS,true); startActivityForResult(intentPreView,REQUEST_CODE_PREVIEW); break; } } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (resultCode == ImagePicker.RESULT_CODE_ITEMS){//添加图片返回 if (data!=null&&requestCode==REQUEST_CODE_SELECT){ ArrayList<ImageItem> images = (ArrayList<ImageItem>) data.getSerializableExtra(ImagePicker.EXTRA_RESULT_ITEMS); if (images!=null){ selImageList.addAll(images); adapter.setImages(selImageList); Log.e("TAG", "onActivityResult: "+selImageList.get(0).path+" "+selImageList.get(1).path ); } } }else if (resultCode == ImagePicker.RESULT_CODE_BACK){//预览图片返回 if (data!=null&&requestCode == REQUEST_CODE_PREVIEW){ ArrayList<ImageItem> images = (ArrayList<ImageItem>) data.getSerializableExtra(ImagePicker.EXTRA_IMAGE_ITEMS); if (images!=null){ selImageList.clear(); selImageList.addAll(images); adapter.setImages(selImageList); } } } }}最后就是我在源码上的修改了，
首先是ImageRecyclerAdapter.java，这里我只粘出我添加的代码，先写一个函数来更新CheckBox的状态
public void updatecheck(ImageViewHolder holder,int position){ holder.cbCheck.setChecked(false); for (int j = 0;j<mSelectedImages.size();j++){ if (mSelectedImages.get(j).equals(images.get(position-1))){ holder.cbCheck.setChecked(true); } } }然后在onBindViewHolder里面进行调用接着是ImageGrideActivity.java，在activity的回调函数里面设置刷新，注意要放在resultCode为ImagePicker.RESULT_CODE_BACK的条件里面，即：
if (resultCode == ImagePicker.RESULT_CODE_BACK) { isOrigin = data.getBooleanExtra(ImagePreviewActivity.ISORIGIN, false); mRecyclerAdapter.notifyDataSetChanged(); }写到这儿，之前我所说的bug就解决了，另外发现，，，还有一个bug，，就是选择图片的预览界面的返回按钮点击后不会激起activity的回调，最后发现是没有findViewById，以及setOnClickListener，所以在ImagePreviewActivity初始化控件的时候添加上就可以了mBtnBack = (ImageView) topBar.findViewById(R.id.btn_back); mBtnBack.setVisibility(View.VISIBLE); mBtnBack.setOnClickListener(this);
到这儿所有想要的效果就都实现了，欢迎各路大神指点。
