3：監(jiān)聽用戶手勢

1：監(jiān)聽來電事件

1:拿到電話管理器
  TelePMG = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
2:創(chuàng)建電話監(jiān)聽器類繼承PhoneStateListener
  class MyPhoneStateListener extends PhoneStateListener{
        //重寫電話狀態(tài)改變的方法
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            switch (state){
                case TelephonyManager.CALL_STATE_IDLE:
                    //電話空閑狀態(tài)
                    System.out.println("空閑狀態(tài)");
                    if(mWindowManager!=null&&toast_view!=null){
                        //掛斷電話的時候移除吐司
                        mWindowManager.removeView(toast_view);
                    }
                    break;
                case TelephonyManager.CALL_STATE_OFFHOOK:
                    //忙碌狀態(tài)，就是占線
                    break;
                case TelephonyManager.CALL_STATE_RINGING:
                    //來電狀態(tài)
                    System.out.println("來電了號碼是"+incomingNumber);
                    //來電后打印吐司
                    showToast(incomingNumber);
                    break;
            }
            super.onCallStateChanged(state, incomingNumber);
        }
    }
3:創(chuàng)建電話監(jiān)聽器的對象
  myPhoneStateListener = new MyPhoneStateListener();
4:使用電話管理器的listen方法綁定監(jiān)聽器
  TelePMG.listen(myPhoneStateListener,PhoneStateListener.LISTEN_CALL_STATE);
5:使用完畢后記得用CLOSE方法關(guān)閉

2：查詢，打開，數(shù)據(jù)庫。匹配正則表達式

public class SelectAdressdb {
    //數(shù)據(jù)庫地址
    public static String  PATH = "data/data/com.joker.mobilesafe/files/address.db";
    private static String adress;
    //封裝查詢的方法
    public  static String SelectAdress (String phone){
        //截取電話前7位
        //匹配正則表達式，不然輸入一個沒有7位的數(shù)字時候會報錯
        System.out.println(phone+"```````````````");
        String regular = "^1[3-8]\\d{9}";
        if (phone.matches(regular)){
            phone = phone.substring(0,7);
            SQLiteDatabase db = SQLiteDatabase.openDatabase(PATH, null, SQLiteDatabase.OPEN_READONLY);
            //表的名字，需要得到查詢結(jié)果的字段，查詢條件，查詢條件的值，是否分組，分組后查詢條件，是否排序
            Cursor cursor = db.query("data1", new String[]{"outkey"}, "id=?", new String[]{phone}, null, null, null);
            if (cursor.moveToNext()){
                //這里傳入的0 是上面第二個條件數(shù)組的下標(biāo)值
                String outkey = cursor.getString(0);
                Cursor indexCursor = db.query("data2", new String[]{"location"}, "id=?", new String[]{outkey}, null, null, null);
                if (indexCursor.moveToNext()){
                    adress = indexCursor.getString(0);
                }else{
                    adress ="未知號碼";
                }
            }else {
                adress ="未知號碼";
            }
        }else {
            int length = phone.length();
            switch (length){
                case 3:
                    adress = "你難道連報警電話都不知道？";
                    break;
                default:
                    adress = "不知道是哪種情況";
                    break;
            }
        }
        return adress;
    }
}

3：監(jiān)聽用戶手勢

1:創(chuàng)建監(jiān)聽用戶手勢的類（第二個參數(shù)傳入監(jiān)聽用戶手勢的監(jiān)聽器）
  GestureDetector gestureDetector = new GestureDetector(this,SimpleOnGestureListener)
2:實現(xiàn)監(jiān)聽器的onFling方法（手勢起點參數(shù)，手勢移動當(dāng)前的參數(shù)，每秒x軸方向移動的像素，每秒y軸方向移動的像素）
  public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
                if (e1.getX()-e2.getX()>0){
                    //下一頁
                    String phone = et_phone_number.getText().toString();
                    if(!TextUtils.isEmpty(phone)){
                        Intent intent = new Intent(Set_up3.this, Set_up4.class);
                        startActivity(intent);
                        SpUtil.PutString(getApplicationContext(), FianlMath.CONTACT_MAN, phone);
                        finish();
                        overridePendingTransition(R.anim.next_anim_in,R.anim.next_anim_out);
                    }else {
                        Toast.makeText(Set_up3.this,"請輸入聯(lián)系人",Toast.LENGTH_SHORT).show();
                    }
                }else if (e1.getX()-e2.getX()<0){
                    //上一頁
                    Intent intent = new Intent(Set_up3.this, Set_up2.class);
                    startActivity(intent);
                    finish();
                    overridePendingTransition(R.anim.up_anim_in,R.anim.up_anim_out);
                }
                return super.onFling(e1, e2, velocityX, velocityY);
            }

重寫ontouchevent方法（這個方法用來捕捉用戶的手勢）
      public boolean onTouchEvent(MotionEvent event) {
        gestureDetector.onTouchEvent(event);
        return super.onTouchEvent(event);
    }
