实现在编辑区位置显示收信人统计信息

将收信人编辑区放到FrameLayout中，给FrameLayout再加一个LinearLayout孩子。

    <FrameLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/transparent">
        <LinearLayout
            android:id="@+id/layout_person"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingLeft="10dip"
            android:paddingRight="10dip"
            android:paddingTop="5dip"
            android:paddingBottom="5dip"
            android:clickable="true"
            android:background="@color/white"
            android:visibility="invisible">
            <TextView
                android:id="@+id/personName"
                android:textSize="14dip"
                android:textColor="@color/black"
                android:clickable="true"
                android:singleLine="true"
                android:ellipsize="middle"
                android:gravity="center_vertical"
                android:layout_gravity="center_vertical"
                android:layout_width="0dip"
                android:layout_weight="1"
                android:layout_height="wrap_content" />
            <ImageView
                android:id="@+id/addPerson"
                android:src="@drawable/ic_add_recipient"
                android:layout_marginLeft="20dip"
                android:layout_width="30dip"
                android:layout_height="30dip"
                android:scaleType="centerInside"/>
        </LinearLayout>
        <!-- 收件人编辑区 -->
        <com.txrj.sms.component.ScrollviewSupportMaxHeight
            android:id="@+id/recipients_scrollview"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/bg_recipient_input"
            android:scrollbars="vertical" >
            <com.txrj.sms.component.RecipientEditor
                android:id="@+id/recipients_editor"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="#00000000" />
        </com.txrj.sms.component.ScrollviewSupportMaxHeight>
    </FrameLayout>   

点击R.id.addPerson按钮时，跳转到联系人列表中。

findViewById(R.id.addPerson).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent it = new Intent(mContext, ContactListActivity.class);
        it.setAction(TxrjConstant.ACTION_ADD_RECIPIENT);
        it.putParcelableArrayListExtra(TxrjConstant.EXTRA_RECIPIENT_LIST, mRecipients);
        startActivityForResult(it, TxrjConstant.REQUEST_ADD_CONTACT);
    }
});

给layoutPerson，mPersonName添加ClickListener。

layoutPerson.setOnClickListener(personClickListener);
mPersonName.setOnClickListener(personClickListener);

显示收信人编辑区，并让收信人编辑框获取焦点。

View.OnClickListener personClickListener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        layoutPerson.setVisibility(View.INVISIBLE);
        layoutEditRecipient.setVisibility(View.VISIBLE);
        mRecipientInput.requestFocus();
    }
};
