- 當(dāng)服務(wù)未開(kāi)啟時(shí)，快速的跳轉(zhuǎn)到開(kāi)啟服務(wù)的界面。
if (!OpenAccessibilitySettingHelper.isAccessibilitySettingsOn(this,
AccessibilitySampleService.class.getName())){// 判斷服務(wù)是否開(kāi)啟
OpenAccessibilitySettingHelper.jumpToSettingPage(this);// 跳轉(zhuǎn)到開(kāi)啟頁(yè)面
} else {
Toast.makeText(this, "服務(wù)已開(kāi)啟", Toast.LENGTH_SHORT).show();
}
用到的方法具體實(shí)現(xiàn)：
/**
* 開(kāi)啟無(wú)障礙服務(wù)幫助類
* Created by mazaiting on 2017/8/18.
*/
public class OpenAccessibilitySettingHelper {
/**
* 跳轉(zhuǎn)到無(wú)障礙服務(wù)設(shè)置頁(yè)面
* @param context 設(shè)備上下文
*/
public static void jumpToSettingPage(Context context){
Intent intent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
/**
* 判斷是否有輔助功能權(quán)限
* @return true 已開(kāi)啟
* false 未開(kāi)啟
*/
public static boolean isAccessibilitySettingsOn(Context context,String className){
if (context == null){
return false;
}
ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningServiceInfo> runningServices =
activityManager.getRunningServices(100);// 獲取正在運(yùn)行的服務(wù)列表
if (runningServices.size()<0){
return false;
}
for (int i=0;i<runningServices.size();i++){
ComponentName service = runningServices.get(i).service;
if (service.getClassName().equals(className)){
return true;
}
}
return false;
}
}
2.模擬點(diǎn)擊，創(chuàng)建模擬點(diǎn)擊的Activity為AccessibilityNormalSampleActivity，并在AndroidManifest.xml將AccessibilityNormalSampleActivity與AccessibilitySampleService配置在同一個(gè)進(jìn)程，若不在同一進(jìn)程，則獲取到的AccessibilityService與AccessibilityEvent為空。
android:process=":BackgroundService"
配置文件為：
<!-- 注冊(cè)輔助功能服務(wù) -->
<service
android:name=".service.AccessibilitySampleService"
android:enabled="true"
android:exported="true"
android:label="@string/accessibility_tip"
android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"
android:process=":BackgroundService">
<!-- android:label="@string/accessibility_tip" 在設(shè)置中顯示的文字 -->
<intent-filter>
<action android:name="android.accessibilityservice.AccessibilityService" />
</intent-filter>
<!-- 通過(guò)xml文件完成輔助功能相關(guān)配置，也可以在onServiceConnected中動(dòng)態(tài)配置 -->
<meta-data
android:name="android.accessibilityservice"
android:resource="@xml/accessibility_config" />
</service>
<activity android:name=".ui.AccessibilityNormalSampleActivity"
android:process=":BackgroundService"></activity>
AccessibilityNormalSampleActivity界面布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/activity_accessibility_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:orientation="vertical">
<CheckBox
android:id="@+id/normal_sample_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="復(fù)選框開(kāi)關(guān)"/>
<RadioButton
android:id="@+id/normal_sample_radiobutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="單選按鈕"/>
<ToggleButton
android:id="@+id/normal_sample_togglebutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"/>
<Button
android:id="@+id/normal_sample_back"
android:layout_marginTop="20dp"
android:text="退出本頁(yè)面"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
3.創(chuàng)建一個(gè)單例類來(lái)控制模擬點(diǎn)擊AccessibilityOperator。
/**
* 控制無(wú)障礙服務(wù)
* Created by mazaiting on 2017/8/18.
*/
public class AccessibilityOperator {
private static final String TAG = "AccessibilityOperator";
private static AccessibilityOperator mInstance;
private AccessibilityOperator(){}
public static AccessibilityOperator getInstance() {
if (mInstance == null){
synchronized (AccessibilityOperator.class){
if (mInstance == null){
mInstance = new AccessibilityOperator();
}
}
}
return mInstance;
}
}
- 創(chuàng)建一個(gè)用來(lái)模擬點(diǎn)擊的界面
在要點(diǎn)擊的Activity中創(chuàng)建一個(gè)Handler來(lái)執(zhí)行延時(shí)消息，創(chuàng)建AccessibilityOperator對(duì)象，在onCreate方法中獲取單例對(duì)象。
private Handler mHandler = new Handler(Looper.getMainLooper());
private AccessibilityOperator accessibilityOperator;
@Override protected void onCreate(Bundle savedInstanceState) {
.....// 省略布局填充
accessibilityOperator = AccessibilityOperator.getInstance();
}
并在onResume方法中進(jìn)行模擬點(diǎn)擊。此處只是調(diào)用AccessibilityOperator中的方法，因此直接貼代碼：
@Override protected void onResume() {
super.onResume();
// 執(zhí)行延時(shí)任務(wù)
clickText();
}
/**
* 按文本點(diǎn)擊
*/
private void clickText() {
clickTextItem("復(fù)選框",1);
clickTextItem("單選按鈕",2);
clickTextItem("關(guān)閉",3);
clickTextItem("退出本頁(yè)面",4);
}
/**
* 文本單個(gè)延時(shí)點(diǎn)擊
* @param text 文本內(nèi)容
* @param num 延時(shí)倍數(shù)
*/
private void clickTextItem(final String text,int num) {
mHandler.postDelayed(new Runnable() {
@Override public void run() {
final boolean isSuccess = accessibilityOperator.clickText(text);
runOnUiThread(new Runnable() {
@Override public void run() {
popToast(isSuccess, text);
}
});
}
},2000*num);
}
/**
* 彈出吐司
* @param isSuccess
* @param msg
*/
private void popToast(boolean isSuccess, String msg) {
if (isSuccess) {
Toast.makeText(this, msg + "點(diǎn)擊成功", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, msg + "點(diǎn)擊失敗", Toast.LENGTH_SHORT).show();
}
}
- 在accessibilityOperator.clickText(text)文本時(shí)，系統(tǒng)會(huì)先調(diào)用AccessibilitySampleService中的onAccessibilityEvent方法，因此在AccessibilityOperator創(chuàng)建一個(gè)updateEvent方法，來(lái)為AccessibilityService服務(wù)與AccessibilityEvent事件賦值。
private AccessibilityService mAccessibilityService;
private AccessibilityEvent mAccessibilityEvent;
/**
* 更新事件
* @param service
* @param event
*/
public void updateEvent(AccessibilityService service, AccessibilityEvent event) {
if (mAccessibilityService == null && service != null){
mAccessibilityService = service;
}
if (event != null){
mAccessibilityEvent = event;
}
}
- 對(duì)AccessibilityService與AccessibilityEvent賦值之后就可以正常使用了。clickText方法的完整內(nèi)容代碼：
/**
* 根據(jù)Text搜索所有符合條件的節(jié)點(diǎn)，模糊搜索方式
* @param text
* @return
*/
public boolean clickText(String text) {
AccessibilityNodeInfo nodeInfo = getRootNodeInfo();
if (nodeInfo!=null){
List<AccessibilityNodeInfo> nodeInfos =
nodeInfo.findAccessibilityNodeInfosByText(text);
return performClick(nodeInfos);
}
return false;
}
/**
* 獲取根節(jié)點(diǎn)
* @return
*/
private AccessibilityNodeInfo getRootNodeInfo() {
Log.e(TAG, "getRootNodeInfo: ");
AccessibilityEvent curEvent = mAccessibilityEvent;
AccessibilityNodeInfo nodeInfo = null;
if (Build.VERSION.SDK_INT >= 16){
if (mAccessibilityService!=null){
// 獲得窗體根節(jié)點(diǎn)
nodeInfo = mAccessibilityService.getRootInActiveWindow();
}
}else {
nodeInfo = curEvent.getSource();
}
return nodeInfo;
}
/**
* 模擬點(diǎn)擊
* @param nodeInfos
* @return true 成功； false 失敗。
*/
private boolean performClick(List<AccessibilityNodeInfo> nodeInfos) {
if (nodeInfos!=null && !nodeInfos.isEmpty()){// 判斷是否非空
AccessibilityNodeInfo nodeInfo;
for (int i=0;i<nodeInfos.size();i++){
nodeInfo = nodeInfos.get(i);// 獲得要點(diǎn)擊的View
// 進(jìn)行模擬點(diǎn)擊
if (nodeInfo.isEnabled()){// 如果可以點(diǎn)擊
return nodeInfo.performAction(AccessibilityNodeInfo.ACTION_CLICK);
}
}
}
return false;
}
getRootNodeInfo()返回的AccessibilityNodeInfo可以對(duì)它進(jìn)行遍歷，查詢它的子節(jié)點(diǎn)
AccessibilityNodeInfo nodeInfo = getRootNodeInfo();
if (nodeInfo!=null){
for (int i=0;i<nodeInfo.getChildCount();i++){
AccessibilityNodeInfo child = nodeInfo.getChild(i);
Log.e(TAG, "clickText: "+child.toString());
}
}
