一、三种常用的定时器
|
||
1.Handler类的postDelayed方法：
|
||
|
||
final Handler mHandler = new Handler();
|
||
Runnable r = new Runnable() {
|
||
|
||
@Override
|
||
public void run() {
|
||
//do something
|
||
//每隔1s循环执行run方法
|
||
mHandler.postDelayed(this, 1000);
|
||
}
|
||
};
|
||
|
||
//主线程中调用：
|
||
mHandler.postDelayed(r, 100);//延时100毫秒
|
||
2.用handler+timer+timeTask方法：
|
||
|
||
final Handler handler = new Handler() {
|
||
@Override
|
||
public void handleMessage(Message msg) {
|
||
if (msg.what == 1) {
|
||
//do something
|
||
}
|
||
super.handleMessage(msg);
|
||
}
|
||
};
|
||
|
||
Timer timer = new Timer();
|
||
TimerTask timerTask = new TimerTask() {
|
||
@Override
|
||
public void run() {
|
||
Message message = new Message();
|
||
message.what = 1;
|
||
handler.sendMessage(message);
|
||
}
|
||
};
|
||
|
||
//主线程中调用：
|
||
timer.schedule(timerTask, 1000, 500);//延时1s，每隔500毫秒执行一次run方法
|
||
3.Thread+handler方法：
|
||
|
||
final Handler handler = new Handler() {
|
||
@Override
|
||
public void handleMessage(Message msg) {
|
||
if (msg.what == 1) {
|
||
//do something
|
||
}
|
||
super.handleMessage(msg);
|
||
|
||
}
|
||
};
|
||
|
||
class MyThread extends Thread {//这里也可用Runnable接口实现
|
||
|
||
@Override
|
||
public void run() {
|
||
while (true) {
|
||
try {
|
||
Thread.sleep(1000);//每隔1s执行一次
|
||
Message msg = new Message();
|
||
msg.what = 1;
|
||
handler.sendMessage(msg);
|
||
} catch (InterruptedException e) {
|
||
e.printStackTrace();
|
||
}
|
||
|
||
}
|
||
}
|
||
}
|
||
//主线程中调用：
|
||
new Thread(new MyThread()).start();
|
||
4.ScheduledThreadPoolExecutor方法：
|
||
|
||
private ScheduledThreadPoolExecutor mThreadPoolExecutor;
|
||
if (mThreadPoolExecutor != null) {
|
||
mThreadPoolExecutor.shutdownNow();
|
||
}
|
||
mThreadPoolExecutor = new ScheduledThreadPoolExecutor(1);
|
||
mThreadPoolExecutor.scheduleWithFixedDelay(new Runnable() {
|
||
@Override
|
||
public void run() {
|
||
}
|
||
}, 0, 500, TimeUnit.MILLISECONDS);
|
||
二、三种延时的快捷方法：
|
||
1.Handler的postDelayed方法：
|
||
|
||
new Handler().postDelayed(new Runnable() {
|
||
|
||
@Override
|
||
public void run() {
|
||
//do something
|
||
}
|
||
}, 1000); //延时1s执行
|
||
2.timer + TimerTask方法：
|
||
|
||
Timer timer = new Timer();
|
||
timer.schedule(new TimerTask() {
|
||
@Override
|
||
public void run() {
|
||
//do something
|
||
}
|
||
},1000);//延时1s执行
|
||
3.Thread方法：
|
||
|
||
new Thread(new Runnable() {
|
||
@Override
|
||
public void run() {
|
||
try {
|
||
Thread.sleep(1000);//延时1s
|
||
//do something
|
||
} catch (InterruptedException e) {
|
||
e.printStackTrace();
|
||
}
|
||
}
|
||
}).start();
|
||
自带定时器 CountDownTimer
|
||
利用 CountDownTimer 实现一个时长为 5 秒的 View 倒计时显示，要求从 5s 开始每隔 1 秒倒计时显示到 1s
|
||
|
||
|
||
CountDownTimer countDownTimer = new CountDownTimer(totalTime, 2000) {
|
||
@Override
|
||
public void onTick(long millisUntilFinished) {
|
||
updateFileData(fileId); //执行任务
|
||
}
|
||
|
||
@Override
|
||
public void onFinish() {
|
||
if (User.getInstance().isLoginIng()) {
|
||
if (countDownTimer != null) {
|
||
countDownTimer.start();
|
||
}
|
||
}
|
||
}
|
||
};
|
||
countDownTimer.start();
|
||
|
||
|
||
三、定时轮询
|
||
为什么使用Service
|
||
普通的线程也可以达到在后台做事情的功能，那么为什么使用 Service呢？是因为 Service是系统的组件，它的优先级比普通的线程要高，
|
||
不容易被系统回收。而且 线程不好控制，Service相对好控制一些。运行在前台的Activity是不会被系统回收 的，而Service如果不想被
|
||
系统回收，就需要在Service中设置一下
|
||
startForeground(int,Notification)
|
||
具体的使用场景有：
|
||
a、拥有长连接QQ
|
||
b、定时轮询
|
||
c、服务里面注册广播接收者。有些广播接收者只能通过代码注册，比如屏幕锁屏、 屏幕解锁、电量发生变化等。
|
||
e、IntentService
|
||

|
||
|
||
|
||
四、沉浸式框架implementation 'com.hannesdorfmann.mosby3:mvp:3.0.0-alpha4'
|
||
|
||
五、获取结点元素 方式一：
|
||
// 遍历root下的子节点有哪些
|
||
for (int i = 0; i < root.getChildCount(); i++) {
|
||
AccessibilityNodeInfo child = root.getChild(i);
|
||
Log.e("TIAOSHI###", "----oneNode:" + child.getClassName() + ":" + child.getText() + ":" + child.getContentDescription());
|
||
if ("dmt.viewpager.DmtViewPager$d".equals(child.getClassName())) {
|
||
Log.e("TIAOSHI###ViewPager", "----twoNode:" + child.getChildCount());
|
||
for (int y = 0; y < child.getChildCount(); y++) {
|
||
AccessibilityNodeInfo child1 = child.getChild(y);
|
||
Log.e("TIAOSHI###", "----twoNode:" + child1.getClassName() + ":" + child1.getText() + ":" + child1.getContentDescription());
|
||
if ("android.widget.TabHost".equals(child1.getClassName())) {
|
||
for (int j = 0; j < child1.getChildCount(); j++) {
|
||
AccessibilityNodeInfo child2 = child1.getChild(j);
|
||
Log.e("TIAOSHI###", "----threeNode:" + child2.getClassName() + ":" + child2.getText());
|
||
|
||
}
|
||
}
|
||
|
||
}
|
||
|
||
}
|
||
}
|
||
|
||
六、横向滑动
|
||
AblViewUtil.scrollHorizontal(10,600,100,600, new GestureCallBack() {
|
||
@Override
|
||
public void succ(GestureDescription gestureDescription) {
|
||
|
||
}
|
||
|
||
@Override
|
||
public void fail(GestureDescription gestureDescription) {
|
||
|
||
}
|
||
});
|
||
|
||
七、停止服务
|
||
AblStepHandler.getInstance().setStop(true);
|
||
|
||
八、定时器
|
||
private void daojishizreo(int a) {
|
||
//启动计时器
|
||
//从0开始发射11个数字为：0-10依次输出，延时0s执行，每1s发射一次。
|
||
mdDisposable = Flowable.intervalRange(0, a + 1, 0, 1, TimeUnit.SECONDS)
|
||
.observeOn(AndroidSchedulers.mainThread())
|
||
.doOnNext(new Consumer<Long>() {
|
||
@Override
|
||
public void accept(Long aLong) throws Exception {
|
||
long b = a - aLong;
|
||
|
||
}
|
||
})
|
||
.doOnComplete(new Action() {
|
||
@Override
|
||
public void run() throws Exception {
|
||
AblStepHandler.getInstance().setStop(true);
|
||
Log.e("TIAOSHI###", "停止了");
|
||
}
|
||
})
|
||
.subscribe();
|
||
}
|
||
|
||
|
||
九、for循环找控件
|
||
/**
|
||
* 寻找留下你的精彩评论
|
||
*/
|
||
private AccessibilityNodeInfo findcoment() {
|
||
AccessibilityNodeInfo infooos=null;
|
||
AccessibilityNodeInfo rootttt = AblService.getInstance().getRootInActiveWindow();
|
||
for (int j = 0; j < rootttt.getChildCount(); j++) {
|
||
AccessibilityNodeInfo child = rootttt.getChild(j);
|
||
Log.e("TIAOSHI###", "----1Node:" + child.getClassName() + ":" + child.getText());
|
||
if (!"dmt.viewpager.DmtViewPager$d".equals(child.getClassName())) {
|
||
// Log.e("TIAOSHI###ViewPager", "----2Node:" + child.getChildCount());
|
||
for (int y = 0; y < child.getChildCount(); y++) {
|
||
AccessibilityNodeInfo child1 = child.getChild(y);
|
||
Log.e("TIAOSHI###", "----2Node:" + child1.getClassName() + ":" + child1.getText());
|
||
// if ("android.widget.LinearLayout".equals(child1.getClassName())) {
|
||
for (int x = 0; x < child1.getChildCount(); x++) {
|
||
AccessibilityNodeInfo child6 = child1.getChild(x);
|
||
Log.e("TIAOSHI###", "----3Node:" + child6.getClassName() + ":" + child6.getText());
|
||
for (int z = 0; z < child6.getChildCount(); z++) {
|
||
AccessibilityNodeInfo child7 = child6.getChild(z);
|
||
// Log.e("TIAOSHI###", "----4Node:" + child7.getClassName() + ":" + child7.getText());
|
||
// if ("android.widget.LinearLayout".equals(child7.getClassName())) {
|
||
for (int r = 0; r < child7.getChildCount(); r++) {
|
||
AccessibilityNodeInfo child2 = child7.getChild(r);
|
||
// Log.e("TIAOSHI###", "----5Node:" + child2.getClassName() + ":" + child2.getText());
|
||
|
||
for (int m = 0; m < child2.getChildCount(); m++) {
|
||
AccessibilityNodeInfo child3 = child2.getChild(m);
|
||
// Log.e("TIAOSHI###", "----6Node:" + child3.getClassName() + ":" + child3.getText());
|
||
for (int n = 0; n < child3.getChildCount(); n++) {
|
||
AccessibilityNodeInfo child4 = child3.getChild(n);
|
||
// Log.e("TIAOSHI###", "----7Node:" + child4.getClassName() + ":" + child4.getText());
|
||
|
||
for (int k = 0; k < child4.getChildCount(); k++) {
|
||
AccessibilityNodeInfo child5 = child4.getChild(k);
|
||
// Log.e("TIAOSHI###", "----8Node:" + child5.getClassName() + ":" + child5.getText());
|
||
|
||
for (int p = 0; p < child5.getChildCount(); p++) {
|
||
AccessibilityNodeInfo child8 = child5.getChild(p);
|
||
// Log.e("TIAOSHI###", "----9Node:" + child8.getClassName() + ":" + child8.getText());
|
||
|
||
}
|
||
|
||
}
|
||
|
||
}
|
||
|
||
}
|
||
}
|
||
// }
|
||
//
|
||
}
|
||
}
|
||
}
|
||
}
|
||
// }
|
||
}
|
||
return infooos;
|
||
}
|
||
|
||
十、超级大坑 目前无解
|
||
在做验证码登录的是时候，getRootInActiveWindow()方法的返回值为null,getWindow()方法也为null,网上查遍资料也没有
|
||
印象笔记搜索：getRootInActiveWindow()方法的返回值为null
|
||
解决办法是让，也没先返回home,然后再打开就可以了。
|
||
|
||
十一、导入手机联系人
|
||
遇到的两个问题：1是内容提供者的配置
|
||
2是权限的问题
|
||
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
|
||
int hasWriteContactsPermission = checkSelfPermission(Manifest.permission.READ_CONTACTS);
|
||
if (hasWriteContactsPermission != PackageManager.PERMISSION_GRANTED){
|
||
requestPermissions(new String[]{Manifest.permission.WRITE_CONTACTS},REQUEST_CODE_ASK_PERMISSIONS);
|
||
// return;
|
||
}
|
||
}
|
||
加入这段代码就好了。
|
||
|
||
十二、绑定服务 https://blog.csdn.net/imxiangzi/article/details/76039978?utm_medium=distribute.pc_relevant_t0.none-task-blog-BlogCommendFromBaidu-1.control&depth_1-utm_source=distribute.pc_relevant_t0.none-task-blog-BlogCommendFromBaidu-1.control

十四、在Android中用广播监听AccessibilityService的开启状态并更新UI界面https://blog.csdn.net/huang826336127/article/details/80139543
|
||
|
||
十五、Android RxJava/RxAndroid：takeWhile，直test测试条件通过才执行链式操作TestAblStep12
|
||
https://blog.csdn.net/zhangphil/article/details/79882700
|
||
|
||
十六、关机重启
|
||
AblStepHandler.getInstance().setStop(false);
|
||
AblStepHandler.sendMsg(AblSteps.STEP_25);
|
||
|
||
十七、退出抖音
|
||
AblStepHandler.getInstance().setStop(false);
|
||
AblStepHandler.sendMsg(AblSteps.STEP_192);//检测我的页面弹出了好友推荐对话框，并关闭
|
||
十八、捕捉弹框（获取事件）
|
||
// TODO Auto-generated method stub
|
||
// System.out.println("Enter->onAccessibilityEvent");
|
||
//判断是否是通知事件typeAnnouncement
|
||
if(event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED){
|
||
List<CharSequence> text = event.getText();
|
||
if(text.size()>0) {
|
||
CharSequence charSequence = text.get(0);
|
||
String s = charSequence.toString();
|
||
Log.e("TIAOSHI", "有弹出");
|
||
Log.e("TIAOSHI", "有弹出==" + s);
|
||
//获取消息来源
|
||
String sourcePackageName = (String) event.getPackageName();
|
||
//获取事件具体信息
|
||
Parcelable parcelable = event.getParcelableData();
|
||
//如果是下拉通知栏消息
|
||
if (parcelable instanceof Notification) {
|
||
} else {
|
||
//其它通知信息，包括Toast
|
||
String toastMsg = (String) event.getText().get(0);
|
||
Log.e("TIAOSHI", "有弹出" + toastMsg);
|
||
Log.e("Latest Toast Message:", "" + toastMsg + " [Source: " + sourcePackageName + "]");
|
||
EventBus.getDefault().post(new SixEvent("success", toastMsg));
|
||
}
|
||
}
|
