问题描述

我想像 greenify 一样使用 AccessibilityService 在 android 设置中单击按钮，但我找不到特定的按钮.请帮帮我.

I want to click button in android settings using AccessibilityService like greenify did, but I cannot find the specific button. please help me.

MyAccessibilityService .java:

public class MyAccessibilityService extends AccessibilityService {

    private static final String TAG = MyAccessibilityService.class
            .getSimpleName();

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        Log.i(TAG, "ACC::onAccessibilityEvent: " + event.getEventType());

        //TYPE_WINDOW_STATE_CHANGED = 32,
        if (AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED == event.getEventType()) {
            AccessibilityNodeInfo nodeInfo = event.getSource();
            Log.i(TAG, "ACC::onAccessibilityEvent: nodeInfo=" + nodeInfo.getText());

            List<AccessibilityNodeInfo> list = nodeInfo.findAccessibilityNodeInfosByViewId("com.android.settings:id/left_button");
            for (AccessibilityNodeInfo node : list) {
                Log.i(TAG, "ACC::onAccessibilityEvent: " + event.getEventType()
                        + " " + node);
            }

仅当 type 为 TYPE_WINDOW_STATE_CHANGED 时，我才能获取 nodeInfo 对象.

Only when type is TYPE_WINDOW_STATE_CHANGED , I could get the nodeInfo object.

推荐答案

打开一个应用的 Appinfo 并启用强制关闭按钮进行测试:

Open one app's Appinfo with force close button enabled to test:

public class MyAccessibilityService extends AccessibilityService {
    private static final String TAG = MyAccessibilityService.class
            .getSimpleName();

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        Log.i(TAG, "ACC::onAccessibilityEvent: " + event.getEventType());

        //TYPE_WINDOW_STATE_CHANGED == 32
        if (AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED == event
                .getEventType()) {
            AccessibilityNodeInfo nodeInfo = event.getSource();
            Log.i(TAG, "ACC::onAccessibilityEvent: nodeInfo=" + nodeInfo);
            if (nodeInfo == null) {
                return;
            }

            List<AccessibilityNodeInfo> list = nodeInfo
                    .findAccessibilityNodeInfosByViewId("com.android.settings:id/left_button");
            for (AccessibilityNodeInfo node : list) {
                Log.i(TAG, "ACC::onAccessibilityEvent: left_button " + node);
                node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
            }

            list = nodeInfo
                    .findAccessibilityNodeInfosByViewId("android:id/button1");
            for (AccessibilityNodeInfo node : list) {
                Log.i(TAG, "ACC::onAccessibilityEvent: button1 " + node);
                node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
            }
        }

    }

    @Override
    public void onServiceConnected() {
        Log.i(TAG, "ACC::onServiceConnected: ");
    }

    @Override
    public void onInterrupt() {
        // TODO Auto-generated method stub

    }
}
