类似微信抢红包也就是自动点击按钮实现
1 创建一个类继承AccessibilityService
public class AutoClickService extends AccessibilityService {
@Override
public void onCreate() {
super.onCreate();
}
@Override
protected void onServiceConnected() {
super.onServiceConnected();
}
private boolean onceClick = false;
@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR2)
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
}
@Override
public void onInterrupt() {
}
@Override
public void onDestroy() {
super.onDestroy();
}
2 在Mainfest文件中配置service
<service
android:name=".AutoClickService"
android:label="点击测试"
android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
<intent-filter>
<action android:name="android.accessibilityservice.AccessibilityService" />
</intent-filter>
<meta-data
android:name="android.accessibilityservice"
android:resource="@xml/auto_click_service_config" />
</service>其中android:resource="@xml/auto_click_service_config"配置文件在AndroidStudio中res文件加下xml文件夹中创建auto_click_service_config.xml
如果res文件夹下面没有xml文件夹，可以新建res ——>Android Resources File ——> Resource type 选择xml创建即可。
auto_click_service_config.xml如下
<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
android:accessibilityEventTypes="typeAllMask"
android:accessibilityFeedbackType="feedbackSpoken"
android:canRetrieveWindowContent="true"
android:accessibilityFlags="flagDefault|flagRetrieveInteractiveWindows|flagIncludeNotImportantViews|flagReportViewIds"
android:description="@string/auto_click_service_description"
android:packageNames="com.sz.lyw.demoactivity"
android:notificationTimeout="100" />其中android:packageNames换成你想要监听的APP包名。
注意：很多时候无障碍权限是默认关闭的，需要先判断一下是否已打开该权限
public static boolean isAccessibilitySettingsOn(Context mContext, Class<? extends AccessibilityService> clazz) {
int accessibilityEnabled = 0;
final String service = mContext.getPackageName() + "/" + clazz.getCanonicalName();
try {
accessibilityEnabled = Settings.Secure.getInt(mContext.getApplicationContext().getContentResolver(),
Settings.Secure.ACCESSIBILITY_ENABLED);
} catch (Settings.SettingNotFoundException e) {
e.printStackTrace();
}
TextUtils.SimpleStringSplitter mStringColonSplitter = new TextUtils.SimpleStringSplitter(':');
if (accessibilityEnabled == 1) {
String settingValue = Settings.Secure.getString(mContext.getApplicationContext().getContentResolver(),
Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES);
if (settingValue != null) {
mStringColonSplitter.setString(settingValue);
while (mStringColonSplitter.hasNext()) {
String accessibilityService = mStringColonSplitter.next();
if (accessibilityService.equalsIgnoreCase(service)) {
return true;
}
}
}
}
return false;
}如果没有打开可以通过 startActivity(new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS)); 打开
在上面清单文件配置service时 android:label="点击测试" ，点击红色框，然后允许即可
3 如何点击指定按钮
前两步已经将service创建配置好，接下来就是如何点击指定按钮，处理是在我们自定义的AutoClickService类中
public class AutoClickService extends AccessibilityService {
@Override
public void onCreate() {
super.onCreate();
Utils.logPrint(" onCreate ");
}
@Override
protected void onServiceConnected() {
super.onServiceConnected();
}
private boolean onceClick = false;
@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR2)
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
AccessibilityOperate.getOperate().updateEvent(this, event);
List<AccessibilityNodeInfo> accessibilityNodeInfos =
AccessibilityOperate.getOperate().findNodesByText("怎么着");
AccessibilityOperate.getOperate().setAimVeiwList(accessibilityNodeInfos);
}
@Override
public void onInterrupt() {
Utils.logPrint(" onInterrupt ");
}
@Override
public void onDestroy() {
super.onDestroy();
}
}其中AccessibilityOperate 是一个封装类
public class AccessibilityOperate {
public static AccessibilityOperate operate;
public static AccessibilityOperate getOperate() {
if (null == operate) {
synchronized (AccessibilityOperate.class) {
if (null == operate) {
operate = new AccessibilityOperate();
}
}
}
return operate;
}
private AccessibilityService mAccessibilityService;
private AccessibilityEvent mAccessibilityEvent;
public void updateEvent(AccessibilityService service, AccessibilityEvent event) {
if (service != null && mAccessibilityService == null) {
mAccessibilityService = service;
}
if (event != null) {
mAccessibilityEvent = event;
}
}
public List<AccessibilityNodeInfo> findNodesByText(String text) {
Utils.logPrint("______________________START_________________________");
AccessibilityNodeInfo nodeInfo = getRootNodeInfo();
if (nodeInfo != null) {
Utils.logPrint("toString：" + nodeInfo.toString());
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
//需要在xml文件中声明权限android:accessibilityFlags="flagReportViewIds"
// 并且版本大于4.3 才能获取到view 的 ID
Utils.logPrint("getClassName：" + nodeInfo.getViewIdResourceName());
}
Utils.logPrint("______________________END_________________________");
return nodeInfo.findAccessibilityNodeInfosByText(text);
} else {
Utils.logPrint("findNodesByText nodeInfo is null ");
}
return null;
}
public List<AccessibilityNodeInfo> findNodesById(String viewId) {
AccessibilityNodeInfo nodeInfo = getRootNodeInfo();
if (nodeInfo != null) {
if (Build.VERSION.SDK_INT >= 18) {
return nodeInfo.findAccessibilityNodeInfosByViewId(viewId);
}
}
return null;
}
private AccessibilityNodeInfo getRootNodeInfo() {
AccessibilityEvent curEvent = mAccessibilityEvent;
AccessibilityNodeInfo nodeInfo = null;
if (Build.VERSION.SDK_INT >= 16) {
if (mAccessibilityService != null) {
nodeInfo = mAccessibilityService.getRootInActiveWindow();
}
} else {
nodeInfo = curEvent.getSource();
}
return nodeInfo;
}
private List<AccessibilityNodeInfo> nodeInfos;
public void setAimVeiwList(List<AccessibilityNodeInfo> nodeInfos) {
this.nodeInfos = nodeInfos;
}
public boolean performClick() {
if (nodeInfos != null && !nodeInfos.isEmpty()) {
Utils.logPrint(" size " + nodeInfos.size());
AccessibilityNodeInfo node;
for (int i = 0; i < nodeInfos.size(); i++) {
node = nodeInfos.get(i);
// 获得点击View的类型
Utils.logPrint("node.toString()：" + node.toString());
// 进行模拟点击
if (node.isEnabled()) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
return node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
}
}
}
} else {
Utils.logPrint(" nodeInfos is null or empty ");
}
return false;
}
}AccessibilityOperate.getOperate().findNodesByText("怎么着"); 是我监听的APP界面有一个Button,按钮的text是 怎么着；
其中 performClick（）方法是在满足指定条件下调用；
我创建了一个AndroidAutoClickDemo的项目监听上图项目DemoActivity
然后在AndroidAutoClickDemo开启一个定时每6秒调用一次AccessibilityOperate.getOperate().performClick();
DemoActivity项目中就会在按钮被点击时弹出一个Toast;
具体点击策略视情况决定；
