当前创建的Application,TeachCourse可以确定支持Android API版本为21,无法运行在当期API版本19的模拟器上 3.解决办法:打开manifest文件,修改如下:android:minSdkVersion...基本上没有区别,主要是一些bug修复。 2表示比1版本更高一些,但既不是主要版本变更,也不是次要版本变更。 所以更新基本不会涉及功能及api变化。 View缺省为可见的,在应用可以通过setVisibility 修改View的可见性,View可用性可以有如下三种状态: View.VISIBLE View可见 View.INVISIBLE View不可以见,但仍然占据可见时...嗯,你可以选着的,19应该是Android4.2吧,你可以去官网下载,API从15到23,API 23就到6.0了。 在布局文件中手写ListView标签试试,或者关闭布局文件页面重新打开可能是下载的服务器地址被墙了/reference/packages.html 这个是最全的,就是英文看起来有点儿麻烦。 有中文的,不过翻译不全而且翻译的不好。建议看英文文档不需要下载, 你下载android的SDK里面就有api文档 例如 解压android的sdk即 android-sdk-windows-2.1 后,就可以在android-sdk-windows-2.1的文件夹下看到一个documenta...你的程序使用的API版本为12 但是你的模拟器的API版本却是0 换一e个d模拟器,将API版本换成8 就可以8了p。。。 zi颉oЗlЕ┓ek萤j困vrXЁoЗ hprof-conv.exe如果不存在的话,从别的地方copy过来一个就行。如果存在的还报这个错误,考虑是不是adb.exe的问题。

作者：janking
字体：[ ] 类型：转载 时间：
这篇文章主要介绍了Android实现QQ抢红包插件,可以支持抢QQ拼手气红包，普通红包，口令红包，感兴趣的小伙伴们可以参考一下
又想到快要过年了，到时候还不知道群里要发好多红包，所以我将之前在网上宕的一份微信抢红包的代码修改了一下，实现了QQ抢红包！可以支持抢QQ拼手气红包，普通红包，口令红包，现在再也不怕20年单身手速的人跟我抢红包了！
先看测试效果图：
1.抢QQ口令红包&
&&&&&&&&&&&&&&&&&&&&&&&&&&&&
&可以看见，只要红包一发出，自动填写口令并发出，帮你将红包抢到手！
2.抢QQ拼手气红包&&&&&&&&&&&&&&&&&
拼手气红包也是一样，只要红包一发出，自动帮你把红包抢到手，是不是很爽的感觉？
3.抢QQ好友发送的红包
只要好友或者群里的人把红包一发出，就会第一时间让你抢到红包！所以只要在群里面开启插件，抢红包从来都是百发百中！好了废话不多说了，也不吹嘘有多牛多好了，下面直接给大家上代码：
MainActivity:
/*MainActivity中的代码基本没改变：*/
public class MainActivity extends AppCompatActivity {
private final Intent mAccessibleIntent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS);
private Button switchP
@Overrideprotected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
switchPlugin = (Button) findViewById(R.id.button_accessible);
updateServiceStatus();
/*开启插件的按钮*/
public void onButtonClicked(View view) {startActivity(mAccessibleIntent);}
@Overrideprotected void onResume() {
super.onResume();
updateServiceStatus();
private void updateServiceStatus() {
boolean serviceEnabled =
AccessibilityManager accessibilityManager = (AccessibilityManager) getSystemService(Context.ACCESSIBILITY_SERVICE);
List&AccessibilityServiceInfo& accessibilityServices = accessibilityManager.getEnabledAccessibilityServiceList(AccessibilityServiceInfo.FEEDBACK_GENERIC);
for (AccessibilityServiceInfo info : accessibilityServices) {
if (info.getId().equals(getPackageName() + "/.QQHongbaoService")) {
serviceEnabled =
if (serviceEnabled) {
switchPlugin.setText("关闭插件");
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
switchPlugin.setText("开启插件");
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);}
这里是MainActivity中的全部代码，是不是很少的样子，主要是实现了一个按钮去开启ACCESSIBILITY_SERVICE。这个插件主要就是借助AccessibilityService这个服务来实现。所以剩下的代码就都在这个服务中了！
QQHongbaoService：
public class QQHongbaoService extends AccessibilityService {
private static final String WECHAT_OPEN_EN = "Open";
private static final String WECHAT_OPENED_EN = "You've opened";
private final static String QQ_DEFAULT_CLICK_OPEN = "点击拆开";
private final static String QQ_HONG_BAO_PASSWORD = "口令红包";
private final static String QQ_CLICK_TO_PASTE_PASSWORD = "点击输入口令";
private boolean mLuckyMoneyR
private String lastFetchedHongbaoId =
private long lastFetchedTime = 0;
private static final int MAX_CACHE_TOLERANCE = 5000;
private AccessibilityNodeInfo rootNodeI
private List&AccessibilityNodeInfo& mReceiveN
@TargetApi(Build.VERSION_CODES.KITKAT)
public void recycle(AccessibilityNodeInfo info) {
if (info.getChildCount() == 0) {
/*这个if代码的作用是：匹配“点击输入口令的节点，并点击这个节点”*/
if(info.getText()!=null&&info.getText().toString().equals(QQ_CLICK_TO_PASTE_PASSWORD)) {
info.getParent().performAction(AccessibilityNodeInfo.ACTION_CLICK);
/*这个if代码的作用是：匹配文本编辑框后面的发送按钮，并点击发送口令*/
if (info.getClassName().toString().equals("android.widget.Button") && info.getText().toString().equals("发送")) {
info.performAction(AccessibilityNodeInfo.ACTION_CLICK);
for (int i = 0; i & info.getChildCount(); i++) {
if (info.getChild(i) != null) {
recycle(info.getChild(i));
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public void onAccessibilityEvent(AccessibilityEvent event) {
this.rootNodeInfo = event.getSource();
if (rootNodeInfo == null) {
mReceiveNode =
checkNodeInfo();
/* 如果已经接收到红包并且还没有戳开 */
if (mLuckyMoneyReceived && (mReceiveNode != null)) {
int size = mReceiveNode.size();
if (size & 0) {
String id = getHongbaoText(mReceiveNode.get(size - 1));
long now = System.currentTimeMillis();
if (this.shouldReturn(id, now - lastFetchedTime))
lastFetchedHongbaoId =
lastFetchedTime =
AccessibilityNodeInfo cellNode = mReceiveNode.get(size - 1);
if (cellNode.getText().toString().equals("口令红包已拆开")) {
cellNode.getParent().performAction(AccessibilityNodeInfo.ACTION_CLICK);
if (cellNode.getText().toString().equals(QQ_HONG_BAO_PASSWORD)) {
AccessibilityNodeInfo rowNode = getRootInActiveWindow();
if (rowNode == null) {
Log.e(TAG, "noteInfo is　null");
recycle(rowNode);
mLuckyMoneyReceived =
private void checkNodeInfo() {
if (rootNodeInfo == null) {
/* 聊天会话窗口，遍历节点匹配“点击拆开”，“口令红包”，“点击输入口令” */
List&AccessibilityNodeInfo& nodes1 = this.findAccessibilityNodeInfosByTexts(this.rootNodeInfo, new String[]{QQ_DEFAULT_CLICK_OPEN, QQ_HONG_BAO_PASSWORD, QQ_CLICK_TO_PASTE_PASSWORD, "发送"});
if (!nodes1.isEmpty()) {
String nodeId = Integer.toHexString(System.identityHashCode(this.rootNodeInfo));
if (!nodeId.equals(lastFetchedHongbaoId)) {
mLuckyMoneyReceived =
mReceiveNode = nodes1;
private String getHongbaoText(AccessibilityNodeInfo node) {
/* 获取红包上的文本 */
AccessibilityNodeInfo i = node.getParent().getChild(0);
content = i.getText().toString();
} catch (NullPointerException npe) {
private boolean shouldReturn(String id, long duration) {
if (id == null)
// 名称和缓存不一致
if (duration & MAX_CACHE_TOLERANCE && id.equals(lastFetchedHongbaoId)) {
private List&AccessibilityNodeInfo& findAccessibilityNodeInfosByTexts(AccessibilityNodeInfo nodeInfo, String[] texts) {
for (String text : texts) {
if (text == null)
List&AccessibilityNodeInfo& nodes = nodeInfo.findAccessibilityNodeInfosByText(text);
if (!nodes.isEmpty()) {
if (text.equals(WECHAT_OPEN_EN) && !nodeInfo.findAccessibilityNodeInfosByText(WECHAT_OPENED_EN).isEmpty()) {
return new ArrayList&&();
public void onInterrupt() {}
QQHongbaoService的全部代码也在这里，代码不多。首先，在这个服务中主要是通过findAccessibilityNodeInfosByText这个方法去获我们需要的节点；然后用performAction(AccessibilityNodeInfo.ACTION_CLICK)这个方法去点击红包节点，关键思路大概就是这样！另外如果是口令红包，我们需要先按照上面的步骤将红包戳开，然后通过performAction(AccessibilityNodeInfo.ACTION_CLICK)去点击输入口令，最后再通过点击去发送即可实现！QQHongbaoService需要在AndroidManifest.xml文件中注册，
注册的&application&节点如下图：
总体来看，只是将微信抢红包的代码做了少量的修改，在这里要感谢各位大神对微信抢红包源码的贡献！最后也希望这篇文章能给大家有所帮助，在抢红包大战中虐死单身狗，再也不怕你20年的单身手速了！！！
