在前面的幾章里面寫了顯示、鍵盤、撥號、刪除功能，這里我將他們進行組合，形成一個撥號鍵盤全部功能。首先是布局

?

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"tools:context=".SipHome" ><RelativeLayoutandroid:id="@+id/topField"android:layout_width="fill_parent"android:layout_height="0dip"android:layout_marginBottom="0dip"android:layout_weight="@integer/dialpad_layout_weight_digits"android:background="@drawable/dialpad_background"android:orientation="horizontal"android:padding="0dip" ><com.jwzhangjie.pjsip.ui.dialpad.DigitsEditTextandroid:id="@+id/digitsText"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@android:color/transparent"android:contentDescription="@string/description_digits_edittext"android:gravity="center"android:imeActionLabel="@string/call"android:imeOptions="actionGo"android:nextFocusRight="@+id/accountChooserButton"android:textAppearance="@style/DialtactsDigitsTextAppearance"android:textColor="@android:color/white" /></RelativeLayout><include layout="@layout/dialpad_compose_3x5" /> </LinearLayout>

dialpad_compose_3x5：

<?xml version="1.0" encoding="utf-8"?> <merge xmlns:android="http://schemas.android.com/apk/res/android" ><com.jwzhangjie.pjsip.widgets.Dialpadandroid:id="@+id/dialPad"android:layout_width="match_parent"android:layout_height="0dip"android:layout_gravity="center_horizontal"android:layout_weight="@integer/dialpad_layout_weight_dialpad"android:background="@drawable/dialpad_background"android:paddingBottom="10dip"android:paddingLeft="5dip"android:paddingRight="5dip" /><Viewandroid:layout_width="match_parent"android:layout_height="@dimen/dialpad_vertical_margin"android:background="#66000000" /><com.jwzhangjie.pjsip.widgets.DialerCallBarandroid:id="@+id/dialerCallBar"android:layout_width="match_parent"android:layout_height="0dip"android:layout_gravity="center_horizontal"android:layout_weight="@integer/dialpad_layout_weight_additional_buttons"android:background="@drawable/dialpad_background"android:orientation="horizontal" /></merge>

代碼如下：
