相信做app的都遇到要分享朋友圈,或者把东西分享给别人的这个功能,下面就是实现这个功能的代码。
要是遇到什么问题,在评论区留言,我会在第一时间回复哦!!!

1、第一步添加依赖

    implementation 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:+'
    implementation 'com.android.support:design:27.1.1'

2、写一个分享的界面layout_popup_share.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/bgcolor_tabbar"
    android:gravity="center"
    android:orientation="horizontal"
    android:paddingTop="16dp"
    android:paddingBottom="16dp">

    <Button
        android:id="@+id/bottom_share_qq"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@null"
        android:drawableTop="qq图片在最下面自己下载,自己导入吧,嘻嘻"
        android:scaleType="center"
        android:textColor="#666666"
        android:text="QQ"
        android:visibility="gone" />

    <Button
        android:id="@+id/bottom_share_qzone"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:background="@null"
        android:drawableTop="qq空间图片在最下面自己下载,自己导入吧,嘻嘻"
        android:scaleType="center"
        android:textColor="#666666"
        android:text="QQ空间"
        android:visibility="gone" />

    <Button
        android:id="@+id/bottom_share_wechat"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:textColor="#666666"
        android:layout_marginLeft="40dp"
        android:background="@null"
        android:drawableTop="微信图片在最下面自己下载,自己导入吧,嘻嘻"
        android:scaleType="center"
        android:text="微信" />

    <Button
        android:id="@+id/bottom_share_wxcircle"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:layout_marginRight="40dp"
        android:textColor="#666666"
        android:background="@null"
        android:drawableTop="微信朋友圈图片在最下面自己下载,自己导入吧,嘻嘻"
        android:scaleType="center"
        android:text="朋友圈" />

    <Button
        android:id="@+id/bottom_share_sina"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:textColor="#666666"
        android:background="@null"
        android:drawableTop="新浪微博图片在最下面自己下载,自己导入吧,嘻嘻"
        android:scaleType="center"
        android:text="微博"
        android:visibility="gone" />
    <TextView
        android:id="@+id/version_name_tv"
        android:visibility="gone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
</LinearLayout>

3、新建类WeChatShareUtil


import android.content.Context;
import android.graphics.Bitmap;


import com.tencent.mm.opensdk.modelmsg.SendMessageToWX;
import com.tencent.mm.opensdk.modelmsg.WXImageObject;
import com.tencent.mm.opensdk.modelmsg.WXMediaMessage;
import com.tencent.mm.opensdk.modelmsg.WXTextObject;
import com.tencent.mm.opensdk.modelmsg.WXWebpageObject;
import com.tencent.mm.opensdk.openapi.IWXAPI;
import com.tencent.mm.opensdk.openapi.WXAPIFactory;

import java.io.ByteArrayOutputStream;

public class WeChatShareUtil {

    //从官网申请的合法appId
    public static final String APP_ID = "xxxx";

    private static final int TIMELINE_SUPPORTED_VERSION = 0x21020001;

    //IWXAPI是第三方app和微信通信的openapi接口
    private IWXAPI api;
    private Context context;
    public static WeChatShareUtil weChatShareUtil;

    public static WeChatShareUtil getInstance(Context context) {
        if (weChatShareUtil == null) {
            weChatShareUtil = new WeChatShareUtil();
        }
        if (weChatShareUtil.api != null) {
            weChatShareUtil.api.unregisterApp();
        }
        weChatShareUtil.context = context;
        weChatShareUtil.regToWx();
        return weChatShareUtil;
    }

    //注册应用id到微信
    private void regToWx() {
        //通过WXAPIFactory工厂,获取IWXAPI的实例
        api = WXAPIFactory.createWXAPI(context, APP_ID, true);
        //将应用的appId注册到微信
        api.registerApp(APP_ID);
    }

    /**
     * 分享文字到朋友圈或者好友
     *
     * @param text  文本内容
     * @param scene 分享方式:好友还是朋友圈
     */
    public boolean shareText(String text, int scene) {
        //初始化一个WXTextObject对象,填写分享的文本对象
        WXTextObject textObj = new WXTextObject();
        textObj.text = text;
        return share(textObj, text, scene);
    }

    /**
     * 分享图片到朋友圈或者好友
     *
     * @param bmp   图片的Bitmap对象
     * @param scene 分享方式:好友还是朋友圈
     */
    public boolean sharePic(Bitmap bmp, int scene) {
        //初始化一个WXImageObject对象
        WXImageObject imageObj = new WXImageObject(bmp);
        //设置缩略图
        Bitmap thumb = Bitmap.createScaledBitmap(bmp, 60, 60, true);
        bmp.recycle();
        return share(imageObj, thumb, scene);
    }

    /**
     * 分享网页到朋友圈或者好友,视频和音乐的分享和网页大同小异,只是创建的对象不同。
     * 详情参考官方文档:

     * @param url         网页的url
     * @param title       显示分享网页的标题

     * @param scene       分享方式:好友还是朋友圈
     */
    public boolean shareUrl(String url, String title, Bitmap thumb, String description, int scene) {
        //初试话一个WXWebpageObject对象,填写url
        WXWebpageObject webPage = new WXWebpageObject();
        webPage.webpageUrl = url;
        return share(webPage, title, thumb, description, scene);
    }

    private boolean share(WXMediaMessage.IMediaObject mediaObject, Bitmap thumb, int scene) {
        return share(mediaObject, null, thumb, null, scene);
    }

    private boolean share(WXMediaMessage.IMediaObject mediaObject, String description, int scene) {
        return share(mediaObject, null, null, description, scene);
    }

    private boolean share(WXMediaMessage.IMediaObject mediaObject, String title, Bitmap thumb, String description, int scene) {
        //初始化一个WXMediaMessage对象,填写标题、描述
        WXMediaMessage msg = new WXMediaMessage(mediaObject);
        if (title != null) {
            msg.title = title;
        }
        if (description != null) {
            msg.description = description;
        }
        if (thumb != null) {
            msg.thumbData = bmpToByteArray(thumb, true);
        }
        //构造一个Req
        SendMessageToWX.Req req = new SendMessageToWX.Req();
        req.transaction = String.valueOf(System.currentTimeMillis());
        req.message = msg;
        req.scene = scene;
        return api.sendReq(req);
    }

    //判断是否支持转发到朋友圈
    //微信4.2以上支持,如果需要检查微信版本支持API的情况, 可调用IWXAPI的getWXAppSupportAPI方法,0x21020001及以上支持发送朋友圈
    public boolean isSupportWX() {
        int wxSdkVersion = api.getWXAppSupportAPI();
        return wxSdkVersion >= TIMELINE_SUPPORTED_VERSION;
    }

    private byte[] bmpToByteArray(final Bitmap bmp, final boolean needRecycle) {
        ByteArrayOutputStream output = new ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.PNG, 100, output);
        if (needRecycle) {
            bmp.recycle();
        }
        byte[] result = output.toByteArray();
        try {
            output.close();
        } catch (Exception e) {
            e.printStackTrace();
        }

        return result;
    }
}

4、在项目文件夹中,创建一个 wxpi 文件夹,一定要是这个名字,大小写都不能错
android实现微信分享、朋友圈分享功能_第1张图片

新建类WXEntryActivity

public class WXEntryActivity extends Activity implements IWXAPIEventHandler {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        IWXAPI api = WXAPIFactory.createWXAPI(this, WeChatShareUtil.APP_ID, false);
        api.handleIntent(getIntent(),this);
        finish();
    }

    @Override
    public void onReq(BaseReq baseReq) {

    }

    @Override
    public void onResp(BaseResp baseResp) {
        String result;
        switch (baseResp.errCode) {
            case BaseResp.ErrCode.ERR_OK:
                result = "分享成功";
                break;
            case BaseResp.ErrCode.ERR_USER_CANCEL:
                result = null;
                break;
            default:
                result = "分享失败";
                break;
        }
        if (result != null) {
//            Toast.makeText(this, baseResp.errCode + result, Toast.LENGTH_SHORT).show();
        }
    }
}

5、在需要点击分享的地方,添加分享的点击事件

    BottomSheetDialog shareDialog;
                shareDialog = new BottomSheetDialog(MineWebViewActivity.this, R.style.BottomDialog);
                View view = View.inflate(MineWebViewActivity.this, R.layout.layout_popup_share, null);

                Button wechat = view.findViewById(R.id.bottom_share_wechat);
                wechat.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Log.d("share", "nativeshare 微信分享 ");
                        if (weChatShareUtil.isSupportWX()) {
                            String desc = "百度";
                            boolean result = true;
                            String url ="http://www.baidu.com";
                            String title="百度";
                            Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.icon_logo);//添加一个logo图片就可以了	
                            result = weChatShareUtil.shareUrl(url,title,bitmap,desc, SendMessageToWX.Req.WXSceneSession);
                        } else {
                            Toast.makeText(MineWebViewActivity.this, "手机上微信版本不支持分享到朋友圈", Toast.LENGTH_SHORT).show();
                        }
                    }
                });
                Button wxcircle = view.findViewById(R.id.bottom_share_wxcircle);
                wxcircle.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {

                        Log.d("share", "nativeshare 微信朋友圈分享 ");
                        if (weChatShareUtil.isSupportWX()) {
                            String desc = "百度";
                            boolean result = true;
                            String url ="http://www.baidu.com";
                            String title="百度";
                            Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.icon_logo);
                            result = weChatShareUtil.shareUrl(url,title,bitmap,desc, SendMessageToWX.Req.WXSceneTimeline);
                        } else {
                            Toast.makeText(MineWebViewActivity.this, "手机上微信版本不支持分享到朋友圈", Toast.LENGTH_SHORT).show();
                        }
                    }
                });
                shareDialog.setContentView(view);
                shareDialog.show();
