本文小編為大家詳細介紹“Android應用中如何接入微信分享功能”，內容詳細，步驟清晰，細節處理妥當，希望這篇“Android應用中如何接入微信分享功能”文章能幫助大家解決疑惑，下面跟著小編的思路慢慢深入，一起來學習新知識吧。
注冊應用信息并下載必要工具
在微信開放平臺注冊應用信息
下載 簽名生成工具獲取待接入應用的簽名
應用信息填入簽名
注意：由于一般調試簽名和正式簽名不一致，測試時可填入測試包的簽名，上線時需要改為正式包的簽名
接入
在build.gradle中，添加如下依賴：
dependencies {
compile 'com.tencent.mm.opensdk:wechat-sdk-android-with-mta:+'
}或：
dependencies {
compile 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:+'
}其中，前者包含統計功能
AndroidManifest.xml中添加權限和微信回調Activity
<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <!-- for mta statistics --> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> <uses-permission android:name="android.permission.READ_PHONE_STATE"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <activity android:name=".WXEntryActivity" android:exported="true" android:screenOrientation="portrait" android:theme="@style/AppTheme.Fullscreen.Translucent"/>
這里使用了一個透明的Activity來處理微信分享結果回調
主題：
<style name="AppTheme.Fullscreen" parent="Theme.AppCompat.NoActionBar"> <item name="android:windowNoTitle">true</item> <item name="android:windowFullscreen">true</item> <item name="android:windowTranslucentNavigation" tools:targetApi="kitkat">true</item> </style> <style name="AppTheme.Fullscreen.Translucent"> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:windowIsTranslucent">true</item> <item name="android:windowAnimationStyle">@android:style/Animation.Translucent</item> </style>
Activity
當微信分享成功，點擊返回App時，微信會主動調用WXEntryActivity，并將結果通過Intent傳給WXEntryActivity，此時調用api.handleIntent(getIntent(), this)對結果進行處理，handleIntent第二個參數為IWXAPIEventHandler，分享結果會在onResp方法中處理，在這里我們發送一個廣播，并在WXShare對象中對該廣播進行監聽
public class WXEntryActivity extends BaseActivity implements IWXAPIEventHandler {
private IWXAPI api;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Logger.i("WXEntryActivity");
WXShare share = new WXShare(this);
api = share
// .register()
.getApi();
//注意：
//第三方開發者如果使用透明界面來實現WXEntryActivity，需要判斷handleIntent的返回值，如果返回值為false，則說明入參不合法未被SDK處理，應finish當前透明界面，避免外部通過傳遞非法參數的Intent導致停留在透明界面，引起用戶的疑惑
try {
if (!api.handleIntent(getIntent(), this)) {
finish();
}
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
Logger.i("onNewIntent");
setIntent(intent);
if (!api.handleIntent(intent, this)) {
finish();
}
}
@Override
public void onReq(BaseReq baseReq) {
}
@Override
public void onResp(BaseResp baseResp) {
Intent intent = new Intent(WXShare.ACTION_SHARE_RESPONSE);
intent.putExtra(WXShare.EXTRA_RESULT, new WXShare.Response(baseResp));
sendBroadcast(intent);
finish();
}
}工具類
public class WXShare {
public static final String APP_ID = "wx0123456789";
public static final String ACTION_SHARE_RESPONSE = "action_wx_share_response";
public static final String EXTRA_RESULT = "result";
private final Context context;
private final IWXAPI api;
private OnResponseListener listener;
private ResponseReceiver receiver;
public WXShare(Context context) {
api = WXAPIFactory.createWXAPI(context, APP_ID);
this.context = context;
}
public WXShare register() {
// 微信分享
api.registerApp(APP_ID);
receiver = new ResponseReceiver();
IntentFilter filter = new IntentFilter(ACTION_SHARE_RESPONSE);
context.registerReceiver(receiver, filter);
return this;
}
public void unregister() {
try {
api.unregisterApp();
context.unregisterReceiver(receiver);
} catch (Exception e) {
e.printStackTrace();
}
}
public WXShare share(String text) {
WXTextObject textObj = new WXTextObject();
textObj.text = text;
WXMediaMessage msg = new WXMediaMessage();
msg.mediaObject = textObj;
// msg.title = "Will be ignored";
msg.description = text;
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = buildTransaction("text");
req.message = msg;
req.scene = SendMessageToWX.Req.WXSceneSession;
boolean result = api.sendReq(req);
Logger.i("text shared: " + result);
return this;
}
public IWXAPI getApi() {
return api;
}
public void setListener(OnResponseListener listener) {
this.listener = listener;
}
private String buildTransaction(final String type) {
return (type == null) ? String.valueOf(System.currentTimeMillis()) : type + System.currentTimeMillis();
}
private class ResponseReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Response response = intent.getParcelableExtra(EXTRA_RESULT);
Logger.d("type: " + response.getType());
Logger.d("errCode: " + response.errCode);
String result;
if (listener != null) {
if (response.errCode == BaseResp.ErrCode.ERR_OK) {
listener.onSuccess();
} else if (response.errCode == BaseResp.ErrCode.ERR_USER_CANCEL) {
listener.onCancel();
} else {
switch (response.errCode) {
case BaseResp.ErrCode.ERR_AUTH_DENIED:
result = "發送被拒絕";
break;
case BaseResp.ErrCode.ERR_UNSUPPORT:
result = "不支持錯誤";
break;
default:
result = "發送返回";
break;
}
listener.onFail(result);
}
}
}
}
public static class Response extends BaseResp implements Parcelable {
public int errCode;
public String errStr;
public String transaction;
public String openId;
private int type;
private boolean checkResult;
public Response(BaseResp baseResp) {
errCode = baseResp.errCode;
errStr = baseResp.errStr;
transaction = baseResp.transaction;
openId = baseResp.openId;
type = baseResp.getType();
checkResult = baseResp.checkArgs();
}
@Override
public int getType() {
return type;
}
@Override
public boolean checkArgs() {
return checkResult;
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(this.errCode);
dest.writeString(this.errStr);
dest.writeString(this.transaction);
dest.writeString(this.openId);
dest.writeInt(this.type);
dest.writeByte(this.checkResult ? (byte) 1 : (byte) 0);
}
protected Response(Parcel in) {
this.errCode = in.readInt();
this.errStr = in.readString();
this.transaction = in.readString();
this.openId = in.readString();
this.type = in.readInt();
this.checkResult = in.readByte() != 0;
}
public static final Creator<Response> CREATOR = new Creator<Response>() {
@Override
public Response createFromParcel(Parcel source) {
return new Response(source);
}
@Override
public Response[] newArray(int size) {
return new Response[size];
}
};
}
}接口
public interface OnResponseListener {
void onSuccess();
void onCancel();
void onFail(String message);
}使用
在需要使用微信分享的Activity中：
@Override
protected void onCreate(Bundle savedInstanceState) {
wxShare = new WXShare(this);
wxShare.setListener(new OnResponseListener() {
@Override
public void onSuccess() {
// 分享成功
}
@Override
public void onCancel() {
// 分享取消
}
@Override
public void onFail(String message) {
// 分享失敗
}
});
}
@Override
protected void onStart() {
super.onStart();
wxShare.register();
}
@Override
protected void onDestroy() {
wxShare.unregister();
super.onDestroy();
}啟動分享
wxShare.share("這是要分享的文字");到這里微信分享就完成啦！
另外，在微信官方例程中，有個定時刷新應用注冊信息的receiver
AndroidManifest.xml中添加:
<receiver android:name=".AppRegister" android:permission="com.tencent.mm.plugin.permission.SEND"> <intent-filter> <action android:name="com.tencent.mm.plugin.openapi.Intent.ACTION_REFRESH_WXAPP"/> </intent-filter> </receiver>
代碼：
public class AppRegister extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
final IWXAPI api = WXAPIFactory.createWXAPI(context, null);
// 將該app注冊到微信
api.registerApp(WXShare.APP_ID);
}
