• 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:

    	@Override

    	}
    	/**
    	 * 含有视频的通话
    	 */
    	@Override

    	}
    	/**
    	 * 删除一个字符
    	 */
    	@Override
    	public void deleteChar() {
    		keyPressed(KeyEvent.KEYCODE_DEL);
    	}
    	/**
    	 * 删除所有的字符
    	 */
    	@Override
    	public void deleteAll() {
    		digits.getText().clear();
    	}
    
    }
    


    最终的显示效果如下:
