Android應用中對於微信分享的實例及問題
如何分享
分享無相應
分享結果如何接收響應
微信 分享回調
(提示幾點關鍵問題： debug_key 一定要獲得對應的簽名碼 然後和weixin官網的appid對應 )
幾點注意事項
1)必須新建一個包位置是
<you package>.wxapi
2)並在此包下簡曆class
WXEntryActivity.class
3)AndroidManifest.xml 需要添加對應Activity的聲明
<activity
android:name="com.yinhang.pos.wxapi.WXEntryActivity"
android:exported="true"
android:theme="@android:style/Theme.Translucent" >
4) WXEntryActivity.class 的基本要求
public class WXEntryActivity extends BaseActivity implements IWXAPIEventHandler{
RelativeLayout
<RelativeLayout xmlns:andro
xmlns:tools="https://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".StartActivity" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
<Button
android:
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="share"
/>
</RelativeLayout>
manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:andro
package="com.example.weishare"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.weishare.activity.StartActivity"
android:exported="true"
android:launchMode="singleTop"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.weishare.wxapi.WXEntryActivity"
android:exported="true"
android:theme="@android:style/Theme.Translucent" >
</activity>
</application>
</manifest>
WXEntryActivity 響應 發送返回的關鍵
public class WXEntryActivity extends Activity implements IWXAPIEventHandler {
private IWXAPI api;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
api = WXAPIFactory.createWXAPI(this,
"your app id", false);
api.handleIntent(getIntent(), this);
}
@Override
public void onReq(BaseReq arg0) {
}
@Override
public void onResp(BaseResp resp) {
int result = 0;
switch (resp.errCode) {
case BaseResp.ErrCode.ERR_OK:
result = R.string.errcode_success;
break;
case BaseResp.ErrCode.ERR_USER_CANCEL:
result = R.string.errcode_cancel;
break;
case BaseResp.ErrCode.ERR_AUTH_DENIED:
result = R.string.errcode_deny;
break;
default:
result = R.string.errcode_unknown;
break;
}
Toast.makeText(this, result, Toast.LENGTH_LONG).show();
// TODO 微信分享 成功之後調用接口
this.finish();
}
}
StartActivity
public class StartActivity extends Activity {
private static final String APP_ID = "your app id";
private IWXAPI api;
private static final String text = "sdafljsalfdkj";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
findViewById(R.id.btn_share).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
final EditText editor = new EditText(StartActivity.this);
editor.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
editor.setText("默認發送信息");
// MMAlert.showAlert(StartActivity.class, "title", editor, "ok", "cancel", new DialogInterface.OnClickListener())
regToWx();
// 初始化一個WXTextObject對象
WXTextObject textObj = new WXTextObject();
textObj.text = text;
// 用WXTextObject對象初始化一個WXMediaMessage對象
WXMediaMessage msg = new WXMediaMessage();
msg.mediaObject = textObj;
// 發送文本類型的消息時，title字段不起作用
// msg.title = "Will be ignored";
msg.description = text;
// 構造一個Req
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = String.valueOf(System.currentTimeMillis());//buildTransaction("text"); // transaction字段用於唯一標識一個請求
req.message = msg;
// req.scene = isTimelineCb.isChecked() ? SendMessageToWX.Req.WXSceneTimeline : SendMessageToWX.Req.WXSceneSession;
Log.e("",api.sendReq(req) + "----------------");
// 調用api接口發送數據到微信
api.sendReq(req);
}
});
}
private void regToWx(){
api = WXAPIFactory.createWXAPI(this, APP_ID, true);
api.registerApp(APP_ID);
}
@Override
protected void onRestart() {
// TODO Auto-generated method stub
super.onRestart();
// Toast.makeText(this, "onRestart sdkjflsaj", Toast.LENGTH_LONG).show();
Log.e(this.getApplication().toString(), "---------onRestart-----------------------");
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
// Toast.makeText(this, "onResume lasdkjflsaj", Toast.LENGTH_LONG).show();
Log.e(this.getApplication().toString(), "---------onResume-----------------------");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.start, menu);
return true;
}
// @Override
// public void onReq(BaseReq arg0) {
// // TODO Auto-generated method stub
//// Toast.makeText(this, "onReqonReqonReqlasdkjflsaj", Toast.LENGTH_LONG).show();
// Log.e(this.getApplication().toString(), "---------onReq-----------------------");
// }
//
// @Override
// public void onResp(BaseResp arg0) {
// // TODO Auto-generated method stub
//// Toast.makeText(this, "onResponResponRespasdkjflsaj", Toast.LENGTH_LONG).show();;
// Log.e(this.getApplication().toString(), "---------onResp-----------------------");
//
//
// }
}
