大佬教程收集整理的这篇文章主要介绍了android – 如何使用AccessibilityService单击设置中的按钮？，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我想在使用Accessibilityservice的 android设置中单击按钮,就像greenify一样,但我找不到具体的按钮.请帮我. @H_683_2@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);
            }@H_772_5@ 
 编辑： 
 只有当type为TYPE_WINDOW_STATE_CHANGED时,我才能得到nodeInfo对象.

解决方法

打开一个应用程序的Appinfo,启用强制关闭按钮进行测试：

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

    }
