Android使用AccessibilityService

标签：log type AccessibilityEvent AccessibilityService 使用 Android TYPE event VIEW

介绍

AccessibilityService设计初衷在于帮助残障用户使用android设备和应用，在后台运行，可以监听用户界面的一些状态转换，例如页面切换、焦点改变、通知、Toast等，并在触发AccessibilityEvents时由系统接收回调。后来被开发者另辟蹊径，用于一些插件开发，比如微信红包助手，还有一些需要监听第三方应用的插件。

AcyService 

import android.accessibilityservice.AccessibilityService;
import android.view.accessibility.AccessibilityEvent;

public class AcyService extends AccessibilityService {

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        PrintUtils.printEvent(event);
    }


    @Override
    public void onInterrupt() {
        PrintUtils.log("onInterrupt");
    }

    @Override
    protected boolean onGesture(int gestureId) {
        PrintUtils.log("onGesture");
        return super.onGesture(gestureId);
    }

    @Override
    protected void onServiceConnected() {
        super.onServiceConnected();
        PrintUtils.log("onServiceConnected");

    }


}

所有用法输出，代码是这个人的，我们这行，代码都是祖传，一个人写的代码，几万人用毫不夸张

    public static void log(CharSequence log) {

            case AccessibilityEvent.TYPE_GESTURE_DETECTION_START:

        }

        for (CharSequence txt : event.getText()) {
            log("text:" + txt);
        }

        log("-------------------------------------------------------------");
    }
}

MainActivity

        Intent intent = new Intent(android.provider.Settings.ACTION_ACCESSIBILITY_SETTINGS);
        startActivity(intent);

manifest文件中添加

   <service
        android:name=".AcyService"
        android:enabled="true"
        android:exported="true"
        android:label="@string/app_name"
        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/services_config" />
    </service>

services_config放xml中

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeAllMask"
    android:accessibilityFeedbackType="feedbackGeneric"
    android:accessibilityFlags="flagReportViewIds"

    android:canRetrieveWindowContent="true"
    android:description="@string/app_name"
    android:notificationTimeout="100" />
