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

【测试步骤】长按一条接收到的彩信，快捷菜单——“选择性复制”

【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:

                    AdapterView.AdapterContextMenuInfo info;

                    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()) {

}

//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;

}

//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:layout_width="match_parent"

android:layout_height="wrap_content"

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。
