使用rhino脚本引擎，调用安卓API，申请无障碍权限获取节点信息并且打印出来

可以使用以下代码实现：

import android.accessibilityservice.AccessibilityService;
import android.view.accessibility.AccessibilityNodeInfo;
import org.mozilla.javascript.Context;
import org.mozilla.javascript.Function;
import org.mozilla.javascript.Scriptable;
import org.mozilla.javascript.ScriptableObject;
import org.mozilla.javascript.annotations.JSFunction;

public class RhinoAccessibilityService extends AccessibilityService {

    private Context rhinoContext;
    private Scriptable rhinoScope;

    @Override
    public void onCreate() {
        super.onCreate();
        rhinoContext = Context.enter();
        rhinoScope = rhinoContext.initStandardObjects();
        ScriptableObject.putProperty(rhinoScope, "service", Context.javaToJS(this, rhinoScope));
        ScriptableObject.putProperty(rhinoScope, "printNodeInfo", new PrintNodeInfoFunction());
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Context.exit();
    }

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        // Do nothing
    }

    @Override
    public void onInterrupt() {
        // Do nothing
    }

    @JSFunction
    public void requestAccessibilityPermission() {
        performGlobalAction(GLOBAL_ACTION_ACCESSIBILITY_SETTINGS);
    }

    @JSFunction
    public void printNodeInfo() {
        AccessibilityNodeInfo rootNode = getRootInActiveWindow();
        if (rootNode != null) {
            printNodeInfoRecursive(rootNode, "");
        }
    }

    private void printNodeInfoRecursive(AccessibilityNodeInfo node, String indent) {
        String text = node.getText() != null ? node.getText().toString() : "";
        String className = node.getClassName() != null ? node.getClassName().toString() : "";
        String viewIdResourceName = node.getViewIdResourceName() != null ? node.getViewIdResourceName().toString() : "";
        System.out.println(indent + className + " " + viewIdResourceName + " " + text);
        for (int i = 0; i < node.getChildCount(); i++) {
            AccessibilityNodeInfo childNode = node.getChild(i);
            if (childNode != null) {
                printNodeInfoRecursive(childNode, indent + "  ");
            }
        }
    }

    private class PrintNodeInfoFunction extends Function {
        @Override
        public Object call(Context cx, Scriptable scope, Scriptable thisObj, Object[] args) {
            printNodeInfo();
            return null;
        }
    }
}

然后在你的 Rhino 脚本中，可以这样调用：

service.requestAccessibilityPermission();
service.printNodeInfo();

这将会请求无障碍权限，并打印出当前活动窗口的节点信息。
