这篇文章主要介绍了如何使用Android原生态实现分享转发功能,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获,下面让小编带着大家一起了解一下。

导读:

之前刚学安卓时,写过一篇"Android调用系统shareAPI实现分享转发功能"的文章,随着安卓版本的迭代更新以及其他APP的优化,安卓的这个shareAPI好像失效了,不怎么好使,已经获取不到有分享功能的APP列表,点击分享也会直接崩溃。并不是说我之前那篇文章的代码有错,只能说是时代有了变化,旧的方法已经不能满足新的需求

最近开发一个收款APP,想把分享功能加入进去,然后发现旧的方法已经不行,这就难过了,网上一些大佬建议用第三方APP自带的分享SDK,但是我觉得用第三方的SDK太麻烦了,每个 APP都要申请接口账号和接口密钥,即便是使用其他人封装好的分享框架,也是需要去申请账号密钥的,一点也不方便,还是喜欢安卓原生态写法,简单便捷、一劳永逸。

经过我几番研究,最终完美实现了,效果图如下:

一、xml布局文件

1、res/layout目录下创建share_dialog.xml

                                                       

2、res/layout目录下创建appinfo_item.xml

          

3、在res/values/styles.xml 中,添加以下代码,用来实现弹出窗背景效果:

二、创建一个实体类 AppInfo.java,用来保存应用信息

package net.zy13.skhelper.entity; import android.graphics.drawable.Drawable; /** * APP信息实体类 */public class AppInfo {    private String appName;    private String packageName;    private String versionName;    private int versionCode;    private String launchClassName;    private Drawable appIcon;     public String getAppName() {        return appName;    }     public void setAppName(String appName) {        this.appName = appName;    }     public String getPackageName() {        return packageName;    }     public void setPackageName(String packageName) {        this.packageName = packageName;    }     public String getVersionName() {        return versionName;    }     public void setVersionName(String versionName) {        this.versionName = versionName;    }     public int getVersionCode() {        return versionCode;    }     public void setVersionCode(int versionCode) {        this.versionCode = versionCode;    }     public String getLaunchClassName() {        return launchClassName;    }     public void setLaunchClassName(String launchClassName) {        this.launchClassName = launchClassName;    }     public Drawable getAppIcon() {        return appIcon;    }     public void setAppIcon(Drawable appIcon) {        this.appIcon = appIcon;    }}

三、重写PopupWindow控件SharePopupWindow.java,自定义分享的弹窗

package net.zy13.skhelper.view; import java.io.File;import java.util.List; import android.app.ActionBar.LayoutParams;import android.content.ComponentName;import android.content.Context;import android.content.Intent;import android.graphics.Bitmap;import android.graphics.drawable.ColorDrawable;import android.net.Uri;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.GridView;import android.widget.LinearLayout;import android.widget.PopupWindow;import android.widget.TextView; import androidx.core.content.FileProvider; import net.zy13.skhelper.R;import net.zy13.skhelper.adapter.AppInfoAdapter;import net.zy13.skhelper.entity.AppInfo;import net.zy13.skhelper.utils.LogUtil;import net.zy13.skhelper.utils.MapTable;import net.zy13.skhelper.utils.ShareUtil; public class SharePopupWindow extends PopupWindow {     //每行显示多少个    private static final int NUM = 5;     private View mMenuView;    private GridView mGridView;    private TextView mTextViewClose;    private AppInfoAdapter mAdapter;     private List mAppinfoList;     private String imgpath;    private String shareTitle;    private String shareContent;    public void setImgpath(String imgpath) {        this.imgpath = imgpath;    }    public void setShareTitle(String shareTitle) {        this.shareTitle = shareTitle;    }    public void setShareContent(String shareContent) {        this.shareContent = shareContent;    }     /**     * 构造函数     * @param context     */    public SharePopupWindow(final Context context) {        super(context);        LayoutInflater inflater = (LayoutInflater) context  .getSystemService(Context.LAYOUT_INFLATER_SERVICE);        mMenuView = inflater.inflate(R.layout.share_dialog, null);        //获取控件        mGridView=(GridView) mMenuView.findViewById(R.id.sharePopupWindow_gridView);        mTextViewClose=(TextView) mMenuView.findViewById(R.id.sharePopupWindow_close);        //获取所有的非系统应用        mAppinfoList = ShareUtil.getAllApps(context);        //适配GridView        mAdapter=new AppInfoAdapter(context, mAppinfoList);        mGridView.setAdapter(mAdapter);         //修改GridView        changeGridView(context);         mGridView.setOnItemClickListener(new OnItemClickListener() {             @Override            public void onItemClick(AdapterView parent, View view, int position,                                    long id) {                // TODO Auto-generated method stub                //使用其他APP打开文件                Intent intent = new Intent();                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);                intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);                intent.setAction(Intent.ACTION_VIEW);                //LogUtil.debug("图片地址:"+imgpath);                //我这里分享的是图片,如果你要分享链接和文本,可以在这里自行发挥                Uri uri = FileProvider.getUriForFile(context, "fileprovider", new File(imgpath));                intent.setDataAndType(uri, MapTable.getMIMEType(imgpath));                context.startActivity(intent);            }        });        //取消按钮        mTextViewClose.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View arg0) {                // TODO Auto-generated method stub                dismiss();            }        });        //设置SelectPicPopupWindow的View        this.setContentView(mMenuView);        //设置SelectPicPopupWindow弹出窗体的宽        this.setWidth(LayoutParams.FILL_PARENT);        //设置SelectPicPopupWindow弹出窗体的高        this.setHeight(LayoutParams.WRAP_CONTENT);        //设置SelectPicPopupWindow弹出窗体可点击        this.setFocusable(true);        //设置窗口外也能点击(点击外面时,窗口可以关闭)        this.setOutsideTouchable(true);        //设置SelectPicPopupWindow弹出窗体动画效果        this.setAnimationStyle(R.style.circleDialog);        //实例化一个ColorDrawable颜色为半透明        ColorDrawable dw = new ColorDrawable(0x00000000);        //设置SelectPicPopupWindow弹出窗体的背景        this.setBackgroundDrawable(dw);    }     /**     * 将GridView改成单行横向布局     */    private void changeGridView(Context context) {        // item宽度        int itemWidth = dip2px(context, 90);        // item之间的间隔        int itemPaddingH = dip2px(context, 1);        //计算一共显示多少行;        int size = mAppinfoList.size();        //int row=(size<=NUM) ? 1 :( (size%NUM>0) ? size/NUM+1 : size/NUM );        //每行真正显示多少个        int rowitem = (size

四、使用provider

1、在清单文件AndroidManifest.xml标签内添加provider

                    

注意:要与activity标签同级

2、在res/xml目录添加filepaths.xml,代码如下:

                                            

五、写一个工具类

ShareUtil.java

package net.zy13.skhelper.utils; import android.content.Context;import android.content.Intent;import android.content.pm.ApplicationInfo;import android.content.pm.PackageInfo;import android.content.pm.PackageManager;import android.content.pm.ResolveInfo;import android.graphics.Bitmap; import net.zy13.skhelper.MainApplication;import net.zy13.skhelper.entity.AppInfo; import java.io.BufferedOutputStream;import java.io.File;import java.io.FileOutputStream;import java.io.IOException;import java.util.ArrayList;import java.util.List; public class ShareUtil {    /**     * 查询手机内所有的应用列表     * @param context     * @return     */    public static List getAllApps(Context context) {        List appList = new ArrayList();        PackageManager pm=context.getPackageManager();        List packages = pm.getInstalledPackages(0);        for (int i = 0;i< packages.size();i++) {            PackageInfo packageInfo = packages.get(i);            AppInfo tmpInfo = new AppInfo();            tmpInfo.setAppName(packageInfo.applicationInfo.loadLabel(pm).toString());            tmpInfo.setPackageName(packageInfo.packageName);            tmpInfo.setVersionName(packageInfo.versionName);            tmpInfo.setVersionCode(packageInfo.versionCode);            tmpInfo.setAppIcon(packageInfo.applicationInfo.loadIcon(pm));            //如果非系统应用,则添加至appList            if ((packageInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0) {                //排除当前应用(替换成你的应用包名即可)                if(!packageInfo.packageName.equals("net.zy13.skhelper")) {                    appList.add(tmpInfo);                }            }        }        return  appList;    }    /**     * 保存图片到缓存里     * @param bitmap     * @return     */    public static String SaveTitmapToCache(Bitmap bitmap){        // 默认保存在应用缓存目录里 Context.getCacheDir()        File file=new File(MainApplication.getAppContext().getCacheDir(),System.currentTimeMillis()+".png");        try {            BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file));            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);            bos.flush();            bos.close();        } catch (IOException e) {            e.printStackTrace();        }        return file.getPath();    }}

六、GridView的适配器 AppInfoAdapter.java

package net.zy13.skhelper.adapter; import android.annotation.SuppressLint;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.AdapterView.OnItemClickListener;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.TextView; import net.zy13.skhelper.R;import net.zy13.skhelper.entity.AppInfo; import java.util.List; public class AppInfoAdapter extends BaseAdapter {     private Context context;    private List mAppinfoList;    private OnItemClickListener mOnItemClickLitener;     public AppInfoAdapter(Context context, List mAppinfoList) {        super();        this.context = context;        this.mAppinfoList = mAppinfoList;    }     @Override    public int getCount() {        // TODO Auto-generated method stub        return mAppinfoList.size();    }     @Override    public Object getItem(int arg0) {        // TODO Auto-generated method stub        return null;    }     @Override    public long getItemId(int arg0) {        // TODO Auto-generated method stub        return 0;    }     @SuppressLint("NewApi")    @Override    public View getView(int position, View convertView, ViewGroup parent) {        // TODO Auto-generated method stub        AppInfo appInfo = mAppinfoList.get(position);        // 加载布局        View view;        ViewHolder viewHolder;        if (convertView == null) {            view = LayoutInflater.from(context).inflate(R.layout.appinfo_item, null);            viewHolder = new ViewHolder(view);            // 将ViewHolder存储在View中            view.setTag(viewHolder);        } else {            view = convertView;            // 重新获取ViewHolder            viewHolder = (ViewHolder) view.getTag();         }        //设置控件的值        viewHolder.imageViewIcon.setImageDrawable(appInfo.getAppIcon());        String name=appInfo.getAppName();        viewHolder.textViewName.setText(name);        return view;    }     class ViewHolder {        ImageView imageViewIcon;        TextView textViewName;         public ViewHolder(View view) {            this.imageViewIcon = (ImageView) view.findViewById(R.id.appinfo_item_icon);            this.textViewName = (TextView) view.findViewById(R.id.appinfo_item_name);        }    } }

七、自定义分享窗口SharePopupWindow的调用

 private LinearLayout mLayoutRoot; private ImageView mImageView; //获取根布局mLayoutRoot=(LinearLayout)view.findViewById(R.id.LayoutRoot);//获取图片控件mImageView=(ImageView)view.findViewById(R.id.image_qrcode);  // 获取ImageView图片mImageView.setDrawingCacheEnabled(true);Bitmap bitmap =Bitmap.createBitmap(mImageViewQrcode.getDrawingCache());mImageView.setDrawingCacheEnabled(false);String imgpath=ShareUtil.SaveTitmapToCache(bitmap);//实例化分享窗口SharePopupWindow spw = new SharePopupWindow(mContext);spw.setImgpath(imgpath);// 显示窗口spw.showAtLocation(mLayoutRoot, Gravity.BOTTOM, 0, 0);
