1, 基于百度地图API开发,用于实现地理位置选取,发送,展示,与消息编辑界面切入点有两处,代码如下:
| case R.id.menuitem_location_share: // Begin : add by qiang.liu 2013-12-9 for multi send from contact if (ensureMultiRecipient()) { Toast.makeText(getApplicationContext(), R.string.confirm_send_multi_audio, Toast.LENGTH_SHORT).show(); return; } // End : add by qiang.liu 2013-12-9 for multi send from contact //Begin: add by liuxue 2013-11-26 if (mNetWorkStatus) { if (!rcsIsConnected()) { Toast.makeText(ComposeMessageActivity.this, strNetworkUnavailable, Toast.LENGTH_SHORT).show(); return; } } //End: add by liuxue 2013-11-26 if (isRecipientsEditorVisible() && TextUtils.isEmpty(mRecipientsEditor.getText())) { showToastNoContacts(); return; } //yexiaoyan 20131224 change begin if(!isRcs){ Toast.makeText(getApplicationContext(), R.string.msg_tost_notRcs, Toast.LENGTH_SHORT).show(); return; } //yexiaoyan 20131224 change end // zhangmeie 20131224 change begin Intent intent = new Intent(ComposeMessageActivity.this,LocationActivity.class); intent.putExtra(LocationActivity.MESSAGE_TYPE,LocationActivity.LOCATION_EDITOR); startActivityForResult(intent, REQUEST_CODE_LOCATION_MESSAGE); |
获得经,纬度,地理位置后返回到消息编辑界面切入点如下:
| caseREQUEST_CODE_LOCATION_MESSAGE: { if (sendByRCS && mConversation != null && aService != null && ensureCapabilityRcs(formatNumber(mConversation.getRecipients().get(0).getNumber())) && rcsIsConnected()) { if (mNetWorkStatus) { Bundle bundle = (Bundle)data.getExtras(); double lat =bundle.getDouble(LocationActivity.MESSAGE_LAT); double lng =bundle.getDouble(LocationActivity.MESSAGE_LNG); String mAddress =bundle.getString(LocationActivity.MESSAGE_ADDRESS); try { aService.sendLocation(getSingleRecipientNumber(), lat,lng, mAddress, ""); } catch (Exception ex) { ex.printStackTrace(); }
mConversation.ensureThreadId(); onMessageSent(); } else { String message = getString(R.string.network_not_ready); Toast.makeText(ComposeMessageActivity.this, message, Toast.LENGTH_SHORT) .show(); } } break; |
2, 主要类文件有:
com.android.mms.ui.LocationActivity.java
com.android.mms.ui.LocationMapView.java
com.android.mms.ui.MyBaiduLotion.java
LocationActivity是地理位置选择或详情,若处于选择状态,地图中心位置为手机持有者地理位置,可拖动地图选择目标位置,点击发送按钮,发送位置给接收端;若处于详情状态,中心位置通过选择位置消息经纬度位置,拖动不可再选择位置,发送按钮不可见.
LocationMapView继承百度地图MapView类,新增OnMapViewChangedListener借口,拖动地图调用重写onTouchEvent方法触发OnMapViewChangedListener监听,在 LocationActivity类实现的OnMapViewChangedListener中,获得经纬度,及时更新选中地理位置
MyBaiduLotion主要是通过经纬度逆解析出地理位置
3, 然后必须在配置文件注册百度服务
| <service android:name="com.baidu.location.f" android:enabled="true" android:process=":remote"> <intent-filter> <actionandroid:name="com.baidu.location.service_v3.3" > </action> </intent-filter> </service>
|
4, 独立的百度地图 privatestaticfinal String key = "xxxxxxxxxxxxxxxxxxxx";
5,关于jar与so,在Mms/src/libs文件夹下,导入baidumapapi_v2_3_1.jar,locSDK_3.3.jar,armeabi文件夹(包括libBaiduMapSDK_v2_3_1.so和liblocSDK3.so),若要在源码里面编译必须在Mms/Android.mk加入jar配置信息
| ….................... LOCAL_STATIC_JAVA_LIBRARIES += liblocsdk
LOCAL_STATIC_JAVA_LIBRARIES += liblocbaidusdk …........................ include $(CLEAR_VARS)
................ LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := liblocsdk:libs/locSDK_3.3.jar
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := liblocbaidusdk:libs/baidumapapi_v2_3_1.jar
.................. include $(BUILD_MULTI_PREBUILT) …................... |
注意若要在源码编译必须在Mms/proguard.flags文件中导入百度架包,如下:
| -keep class com.baidu.** { *;
}
-keep class vi.com.gdi.bgl.android.**{
*;
} |
