pjsip视频通信开发(上层应用)之拨号界面整体界面功能实现

在前面的几章里面写了显示、键盘、拨号、删除功能,这里我将他们进行组合,形成一个拨号键盘全部功能。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" >
	
	 <RelativeLayout
        android: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.DigitsEditText
            android: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.Dialpad
        android: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" />

    <View
        android:layout_width="match_parent"
        android:layout_height="@dimen/dialpad_vertical_margin"
        android:background="#66000000" />

    <com.jwzhangjie.pjsip.widgets.DialerCallBar
        android: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>
