解决：长按一条接收到的彩信，快捷菜单“选择性复制”功能错误
【测试结果】功能错误，未实现选择性复制，实际是播放彩信内容
【预期结果】应该选择复制彩信内容
通过分析代码我们定位到以下代码：
private final class MsgListMenuClickListener implements MenuItem.OnMenuItemClickListener {
private MessageItem mMsgItem;
public MsgListMenuClickListener(MessageItem msgItem) {
mMsgItem = msgItem;
}
@Override
public boolean onMenuItemClick(MenuItem item) {
if (mMsgItem == null) {
return false;
}
......
case MENU_SELECT_COPY_MESSAGE_TEXT:
try {
info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
} catch (ClassCastException exception) {
Log.e(TAG, "Bad menuInfo.", exception);
return false;
}
final Cursor cursor = (Cursor) mMsgListAdapter.getItem(info.position);
if (mMsgItem.isSms()) {
showSmsMessageContent(cursor);
} else {
MessageUtils.viewMmsMessageAttachment(ComposeMessageActivity.this,
ContentUris.withAppendedId(Mms.CONTENT_URI, mMsgItem.mMsgId), null,
getAsyncDialog());
}
return true;
......
}
通过对以上代码我们发现，这里对彩信和短信分别进行了处理，在接着追踪代码时我们发现，如果信息为短信则现实短信的详细信息包括发件人，发件时间等，如果信息为彩信则直接进入彩信幻灯片播放界面，并播放幻灯片。与选项描述和原始业务逻辑相违背，因此作出一下修改。
我们只提取信息的文本，如果信息为彩信，并且彩信只有附件，则屏蔽该选项（Select text to copy）。
因此作出以下修改：
修改ComposeMessageActivity文件中， OnCreateContextMenuListener子类中onCreateContextMenu（）方法。
这是修改前的源文件：
......
// Forward is not available for undownloaded messages.
if (msgItem.isDownloaded() && (msgItem.isSms() || msgItem.mIsForwardable)) {
menu.add(0, MENU_FORWARD_MESSAGE, 0, R.string.menu_forward)
.setOnMenuItemClickListener(l);
}
if (!msgItem.isMms() || msgItem.isDownloaded()) {
menu.add(0, MENU_SELECT_COPY_MESSAGE_TEXT, 0, R.string.select_copy_message_text)
.setOnMenuItemClickListener(l);
}
//only failed send message have resend function
if (msgItem.isFailedMessage()) {
menu.add(0, MENU_RESEND, 0, R.string.menu_resend)
.setOnMenuItemClickListener(l);
}
......
下面是修改后的源代码：（将上述代码中蓝色加粗代码修改为下面红色加粗代码）
......
// Forward is not available for undownloaded messages.
if (msgItem.isDownloaded() && (msgItem.isSms() || msgItem.mIsForwardable)) {
menu.add(0, MENU_FORWARD_MESSAGE, 0, R.string.menu_forward)
.setOnMenuItemClickListener(l);
}
String selectText=null;
selectText=msgItem.mBody;
if( (!msgItem.isMms() || msgItem.isDownloaded())&&(selectText!=null)){
menu.add(0, MENU_SELECT_COPY_MESSAGE_TEXT, 0, R.string.select_copy_message_text)
.setOnMenuItemClickListener(l);
}
//only failed send message have resend function
if (msgItem.isFailedMessage()) {
menu.add(0, MENU_RESEND, 0, R.string.menu_resend)
.setOnMenuItemClickListener(l);
}
......
添加SelectTextToCopyActivity文件，该类为对信息文本内容进行自由复制操作界面：

添加activity_select_text_to_copy.xml文件，为相对应布局文件：
<?xml version="1.0" encoding="utf-8"?>
<!-- AddBy:yabin.huang BugID:SWBUG00030439 Date:20140626 --><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/outlayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
android:gravity="center_horizontal"
android:isScrollContainer="true"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="50dip"
android:orientation="vertical" >
<TextView
android:id="@+id/text_select"

android:autoLink="all"
android:linksClickable="false"
android:padding="20dp"
android:textColor="#000000"
android:textSize="18dip" />
</LinearLayout>
</LinearLayout>
并在清单文件中对Activity进行注册：
<activity android:name=".ui.SelectTextToCopyActivity"
android:label="@string/select_copy_message_text"
android:theme="@style/MmsHoloTheme"
android:configChanges="orientation|screenSize|keyboardHidden"
android:launchMode="singleTop" >
</activity>
OK！问题得到解决。
