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.
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);
}
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
}
}
