Android 统计通话时间的小软件

   现在很多人打电话都会使用一个套餐，比较划算。通常一个月有多少分钟免费呼叫，几十到几百条的免费短信。我自己写了一个小软件，可以统计一个月打出的电话总时间，可以帮助使用套餐的同学们把握好免费呼叫的时间。

   一般来讲，android会将通话记录都保存在一个特定的contentprovider中，用手机查看的通话记录也是从里面查询出来的数据。操作这个contentprovider的类就是CallLog类，它有一个内部类Calls，在Calls中对uri等成员都已经做好了定义，可以使用Calls的成员直接进行通话记录的查询。当然，对通话记录的插入也是通过这个类来实现的。

   另外值得一提的是，如果在手机的通话记录中将所有的通话记录都删除了话，是查不出任何数据的。

   程序的界面我采用了AlertDialog的形式，本来实现的功能和要显示的内容就很简单，使用Activity的话感觉有点大。整个程序只有一个类TelTime.java，其实说起来很简单，就是读取出所有的通话记录，然后一条一条地按时间进行分类求和而已。

    @Override
    public void onCancel(DialogInterface dialog) {
        finish();

    }

}

    要只显示一个Dialog，需要把背景的Activity设置为透明的就可以了，这个在manifest文件中进行设置：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android=""
      package="org.test"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-permission android:name="android.permission.READ_CONTACTS" />

    <application android:icon="@drawable/icon" android:label="@string/app_name">

        <activity android:name=".TelTime"
                  android:label="@string/app_name"
                  android:theme="@android:style/Theme.Translucent">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
</manifest>

    对于Dialog的布局也很简单，只是采用了四个TextView。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android=""
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TableLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:shrinkColumns="1"
        android:paddingTop="5dip">
        <TableRow>
            <TextView
                android:id="@+id/outtime"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="20dip"
                android:textColor="#fff00000" />
        </TableRow>
        <TableRow>
            <TextView
                android:id="@+id/intime"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="20dip"
                android:textColor="#ff00ffff"/>
        </TableRow>
          <TableRow>
            <TextView
                android:id="@+id/out"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="20dip"
                android:textColor="#fff0ff00" />
        </TableRow>
        <TableRow>
            <TextView
                android:id="@+id/in"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="20dip"
                android:textColor="#ff00ff00"/>
        </TableRow>
    </TableLayout>
</LinearLayout>

    最后，附上一个示例图片，如果有通话记录还会显示出你最关心的人和最关心你的人。
