Android微信登陸和微信分享，和登陸分享的回撥處理
阿新 • • 發佈：2019-02-19
首先是微信登陸。
直接上程式碼
在點選登陸時候
public class LandActivity extends Activity { private Button land; private LinearLayout skip; private IWXAPI api; private Handler handler=new Handler(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_land); api= WXAPIFactory.createWXAPI(LandActivity.this,"wx9433d9bf10c7a032",true); init(); } public void init(){ land= (Button) findViewById(R.id.land);//登陸 land.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { SharedPreferences sharedPreferences=getSharedPreferences("landingwx", Context.MODE_PRIVATE); SharedPreferences.Editor editor=sharedPreferences.edit(); editor.putString("landingwx","oneland"); editor.commit(); api.registerApp("wx9433d9bf10c7a032"); SendAuth.Req req = new SendAuth.Req(); //授權讀取使用者資訊 req.scope = "snsapi_userinfo"; //自定義資訊 req.state = "beoka"; //向微信傳送請求 api.sendReq(req); handler.postDelayed(new Runnable() { @Override public void run() { finish(); } },20000); } });
這個其實就可以調取登陸了，但是我們還要請求接口才行 。
請求介面 我放到回撥裡面說、
接下來是我們這個分享
public class AboutActivity extends Activity { private ImageView about_b; private ImageView about_update; private TextView share; private IWXAPI api; private int modelIndex; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_about); api= WXAPIFactory.createWXAPI(AboutActivity.this,"wx9433d9bf10c7a032",true); api.registerApp("wx9433d9bf10c7a032"); about_b= (ImageView) findViewById(R.id.about_b); about_b.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { finish(); } }); about_update= (ImageView) findViewById(R.id.about_update); about_update.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Toast toast=Toast.makeText(AboutActivity.this,"已是最新版本",Toast.LENGTH_LONG); toast.setGravity(Gravity.CENTER, 0, 0); toast.show(); } }); share= (TextView) findViewById(R.id.share); share.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Dialog(); } }); } private void share2weixin(int flag) { if (!api.isWXAppInstalled()) { Toast.makeText(AboutActivity.this, "您還未安裝微信客戶端", Toast.LENGTH_SHORT).show(); return; } WXWebpageObject webpage = new WXWebpageObject(); webpage.webpageUrl = "http://mp.weixin.qq.com/s/ObyplzD9MQJ1OcXATN64hQ"; WXMediaMessage msg = new WXMediaMessage(webpage); msg.title = "頭部按摩器"; msg.description = "四川千里倍益康"; Bitmap thumb = BitmapFactory.decodeResource(getResources(), R.mipmap.beoka); msg.setThumbImage(thumb); SendMessageToWX.Req req = new SendMessageToWX.Req(); req.transaction = String.valueOf(System.currentTimeMillis()); req.message = msg; req.scene = flag; api.sendReq(req); finish(); } private void Dialog() { AlertDialog.Builder builder = new AlertDialog.Builder(this); final String[] models = new String[]{"微信好友", "微信朋友圈"}; builder.setTitle("分享給朋友"); //設定標題 builder.setSingleChoiceItems(models, modelIndex, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss();//消除對話方塊 modelIndex = which; if(modelIndex==1){ share2weixin(1); }else if(modelIndex==0) { share2weixin(0);//分享到朋友圈 } } }).show(); } }
這裡我只列舉了一個分享網頁的方法。其他差不多
接下來是回撥
主要就是這裡區分 登陸和分享的回撥處理public class WXEntryActivity extends Activity implements IWXAPIEventHandler{ private IWXAPI api; private String body; private String bod; private String nickname; private String headimgurl; private String unionid; private static final int RETURN_MSG_TYPE_LOGIN = 1; private static final int RETURN_MSG_TYPE_SHARE = 2; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_wxentry); api= WXAPIFactory.createWXAPI(WXEntryActivity.this,"wx9433d9bf10c7a032"); api.registerApp("wx9433d9bf10c7a032"); //等待微信回撥 api.handleIntent(getIntent(), this); } // 微信傳送請求到第三方應用時，會回撥到該方法 @Override public void onReq(BaseReq baseReq) { } // 第三方應用傳送到微信的請求處理後的響應結果，會回撥到該方法 @Override public void onResp(BaseResp baseResp) { Bundle bundle=getIntent().getExtras(); SendAuth.Resp resp=new SendAuth.Resp(bundle);//這個是登陸必須用到的，要用來獲取code值的。 //而區分分享回撥返回的結果和登陸回撥返回的結果 是用baseResp.getType()== ConstantsAPI.COMMAND_SENDAUTH //和baseResp.getType()==ConstantsAPI.COMMAND_SENDMESSAGE_TO_WX //注意哈 這裡的baseResp和resp是不同的哈。resp這個是登陸用到的 //獲取到code之後，需要呼叫介面獲取到access_token if(baseResp.errCode==BaseResp.ErrCode.ERR_OK){ if(baseResp.getType()== ConstantsAPI.COMMAND_SENDAUTH){ String code=resp.token;
