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> 代码如下：
