###1.骚扰拦截需求分析
1.界面
1.1 黑名单列表界面
1.2 添加黑名单界面
2.功能
2.1 黑名单的添加、删除
2.2 拦截电话
2.3 拦截短信
###2.黑名单数据库的创建
1.分析需要的字段
id 主键自增长,phone 电话号码,mode 拦截模式
2.创建数据库打开类BlackNumberDBOpenHelper,继承SQLiteOpenHelper
public class BlackNumberDBOpenHelper extends SQLiteOpenHelper {
public BlackNumberDBOpenHelper(Context context) {
super(context, "address.db", null, 1);
}
//数据库第一次被创建的时候调用,适合初始化数据库的表结构
@Override
public void onCreate(SQLiteDatabase db) {
//id 主键自增长, phone 电话号码 mode 拦截模式
db.execSQL("create table blacknumber (_id integer primary key autoincrement, phone varchar(20),mode varchar(2))");
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
}
}
3.创建数据库数据操作类BlackNumberDao,实现增删改查方法
###3.增删改查单元测试
1.创建测试类TestBlackNumberDao,继承AndroidTestCase,测试增删改查方法
2.在清单文件中对测试类进行如下配置:
2.1 manifest节点下添加
<instrumentation
android:name="android.test.InstrumentationTestRunner"
android:targetPackage="com.hb.mobilesafe" >
</instrumentation>
2.2 application节点下添加
<uses-library android:name="android.test.runner"/>###4.android:layout_weight的用法
1.android:layout_weight:权重比例,将剩余空间按比例分配。只可在线性布局中使用
2.指定android:layout_weight属性后,
如果线性布局是水平的,View的宽度=原有宽度+线性布局剩余空间的占比
如果线性布局是竖直的,View的高度=原有高度+线性布局剩余空间的占比
3.Android官方推荐,在使用android:layout_weight时,
如果线性布局是水平的,要将android:layout_width设置为0dp
如果线性布局是竖直的,要将android:layout_height设置为0dp

###2.挂断电话
//加入权限
<uses-permission android:name="android.permission.CALL_PHONE" /> /**
* 挂断电话
*/
public void endCall() { //系统内部调用方式
//ITelephony.Stub.asInterface(ServiceManager.getService(Context.TELEPHONY_SERVICE));
try { //ServiceManager获取不到,需要反射调用
Class clazz = getClassLoader().loadClass("android.os.ServiceManager");
Method method = clazz.getDeclaredMethod("getService", String.class);
IBinder iBinder = (IBinder) method.invoke(null, Context.TELEPHONY_SERVICE); //挂断电话需要用到AIDL,拷贝需要用到的AIDL文件,ITelephony.aidl和NeighboringCellInfo.aidl,包名要与原包名一致
ITelephony iTelephony = ITelephony.Stub.asInterface(iBinder);
iTelephony.endCall();
} catch (Exception e) {
e.printStackTrace();
}
}
###3.删除呼叫记录
//加入权限
<uses-permission android:name="android.permission.READ_CALL_LOG" />
<uses-permission android:name="android.permission.WRITE_CALL_LOG" /> /**
* 删除黑名单号码的呼叫记录
* @param incomingNumber 来电黑名单号码
*/
public void deleteCallLog(final String incomingNumber) {
final ContentResolver resolver = getContentResolver(); //CallLog.Calls.CONTENT_URI 等价于 Uri.parse("content://call_log/calls");
final Uri uri = Uri.parse("content://call_log/calls");
//利用内容观察者 观察呼叫记录的数据库,如果生成了呼叫记录就立刻删除呼叫记录
resolver.registerContentObserver(uri, true, new ContentObserver(new Handler()) {
@Override
public void onChange(boolean selfChange) {
//当内容观察者观察到数据库的内容变化的时候调用的方法.
super.onChange(selfChange);
resolver.delete(uri, "number=?", new String[]{incomingNumber});
}
});
}
###4.拦截短信
1.注册在清单文件中的广播接收者,无论应用是否启动都会接收到广播,想用开关控制拦截短信的功能,则在代码中注册短信广播接收者
receiver = new InnerSmsReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
filter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY);
registerReceiver(receiver, filter); private class InnerSmsReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
Log.i(Tag,"服务内部广播接受者接收到了短信");
Object[] objs = (Object[]) intent.getExtras().get("pdus");
for(Object obj: objs){
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) obj);
String body = smsMessage.getMessageBody();
if(body.contains("fapiao")){
//你的头发票亮的很 分词技术
Log.i(Tag,"发现发票垃圾短信,拦截");
abortBroadcast();
return;
}
String sender = smsMessage.getOriginatingAddress();
String mode = dao.find(sender);
if("2".equals(mode)||"3".equals(mode)){
Log.i(Tag,"发现黑名单短信,拦截");
abortBroadcast();
}
}
}
}
2.onDestroy中注销
unregisterReceiver(receiver);
receiver = null;###5.导入已存在的数据库
//assert资产目录里面的文件会原封不动的打包到apk里,不生成id /**
* 拷贝归属地的数据库
*/
private void copyAddressDB() {
File file = new File(getFilesDir(), "address.db");
//判断数据库文件是否存在
if (file.exists() && file.length() > 0) {
Log.i(TAG, "数据库存在,无需拷贝");
} else {
new Thread() {
public void run() {
// 把asset资产目录里面的数据库文件(在apk里面的)拷贝到手机系统里面
try {
InputStream is = getAssets().open("address.db");
File file = new File(getFilesDir(), "address.db");
FileOutputStream fos = new FileOutputStream(file);
byte[] buffer = new byte[1024];
int len = -1;
while ((len = is.read(buffer)) != -1) {
fos.write(buffer, 0, len);
}
fos.close();
is.close();
} catch (Exception e) {
e.printStackTrace();
}
};
}.start();
}
}
###6.查询号码归属地
/**
* 查询手机号码的归属地信息
* @param mobilenumber
* @return
*/
public static String findLocation(String mobilenumber) {
String path = "/data/data/com.hb.mobilesafe/files/address.db";
//打开已存在的数据库
SQLiteDatabase db = SQLiteDatabase.openDatabase(path, null,
SQLiteDatabase.OPEN_READONLY);
Cursor cursor = db.rawQuery(
"select location from data2 where id = (select outkey from data1 where id = ?)",
new String[]{mobilenumber.substring(0, 7)});
String location ="";
if(cursor.moveToNext()){
location = cursor.getString(0);
}
cursor.close();
db.close();
return location;
}
###7.判断一个号码是否是手机号码
// ^1[34578]\d{9}$
// ^ 匹配输入字符串的开始位置。
// [] 字符集合。匹配所包含的任意一个字符。
// \d 匹配一个数字字符。
// {} n 是一个非负整数。匹配确定的 n 次。
// $ 匹配输入字符串的结束位置。
boolean result = number.matches("^1[34578]\\d{9}$");###8.给EditText添加文本变化监听器
// 给文本输入框注册一个内容变化的监听器.
et_number.addTextChangedListener(new TextWatcher() {
//当文本变化之前调用的方法,s为改变前字符串,可获取被替换内容
//在s中从start开始的count个字符即将被after个字符替换
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) { }
//当文本变化之后调用的方法,s为改变后字符串,可获取替换内容
//在s中从start开始的before个字符刚刚被count个字符替换
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
if (s.length() >= 10) {
String location = AddressDBDao.findLocation(s.toString());
tv_location.setText("归属地为:" + location);
}
} //当文本变化之后调用的方法,s为改变后字符串,操作s可直接改变EditText内容,EditText内容改变会继续调用beforeTextChanged和onTextChanged方法
//s中有内容被改变
@Override
public void afterTextChanged(Editable s) { }
});
每次输入都会调用3个方法,调用顺序为beforeTextChanged-->onTextChanged-->afterTextChanged
###9.CharSequence、String、Editable
1.CharSequence:接口,只有length()、charAt(int index)、subSequence(int start, int end)、toString()四个方法
2.String:实现了CharSequence接口,具有很多操作字符串的方法,不可修改
3.Editable:实现了CharSequence接口,具有增删改等修改的方法,可修改
###10.动画插值器Interpolator
1.interpolator定义一个动画的变化率(the rate of change)。这使得基本的动画效果(alpha, scale, translate, rotate)得以加速,减速,重复等。
2.常用Interpolator
LinearInterpolator 以常量速率改变
AccelerateInterpolator 加速
DecelerateInterpolator 减速
AccelerateDecelerateInterpolator 先加速后减速
AnticipateInterpolator
OvershootInterpolator
AnticipateOvershootInterpolator
BounceInterpolator 弹跳
CycleInterpolator 循环播放特定的次数,速率改变沿着正弦曲线
###11.监听外拨电话
1.添加权限
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
2.注册广播接收者
receiver = new OutCallReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_NEW_OUTGOING_CALL);
registerReceiver(receiver, filter);
private class OutCallReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
String number = getResultData();
String address = AddressDBDao.findLocation(number);
Toast.makeText(ShowAddressService.this, address, 1).show();
}
}
3.释放资源
@Override
public void onDestroy() {
unregisterReceiver(receiver);
receiver = null;
super.onDestroy();
}
###12.通过WindowManager添加自定义View到窗体
1.添加权限
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
2.获取WindowManager
WindowManager mWM = (WindowManager) getSystemService(WINDOW_SERVICE);
3.自定义View
View mView;
4.设置布局参数
final WindowManager.LayoutParams params = mParams;
params.height = WindowManager.LayoutParams.WRAP_CONTENT;
params.width = WindowManager.LayoutParams.WRAP_CONTENT;
params.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
| WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE
| WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON;
params.format = PixelFormat.TRANSLUCENT;
params.type = WindowManager.LayoutParams.TYPE_TOAST;
5.添加到窗体
mWM.addView(view, mParams);
6.移除View
mWM.removeView(view);
