Java实现安卓手机模拟操作

第一部分：安卓模拟操作基础

1.1 安卓输入系统概述

1.1.1 输入事件传递机制

安卓系统中的输入事件遵循以下传递路径：

1. 硬件层：触摸屏、物理按键等硬件设备产生原始输入信号
2. 内核层：Linux内核通过设备驱动接收原始输入事件
3. 系统服务层：InputManagerService处理输入事件
4. 应用层：事件通过View层级传递到具体应用

1.1.2 输入事件类型

• 按键事件(KeyEvent)：物理按键、键盘输入
• 触摸事件(MotionEvent)：触摸屏交互
• 轨迹球事件(TrackballEvent)：现已较少使用
• 游戏控制器事件：手柄等外设输入

1.2 模拟操作的核心类

1.2.1 Instrumentation类

public class Instrumentation {// 发送按键事件public void sendKeySync(KeyEvent event) { ... }// 发送触摸事件public void sendPointerSync(MotionEvent event) { ... }// 发送字符串public void sendStringSync(String text) { ... }
}

1.2.2 KeyEvent类

public class KeyEvent extends InputEvent implements Parcelable {// 常用按键代码public static final int KEYCODE_HOME = 3;public static final int KEYCODE_BACK = 4;public static final int KEYCODE_DPAD_CENTER = 23;public static final int KEYCODE_ENTER = 66;// 构造方法public KeyEvent(long downTime, long eventTime, int action, int code, int repeat) { ... }
}

1.2.3 MotionEvent类

public abstract class MotionEvent extends InputEvent implements Parcelable {// 动作类型public static final int ACTION_DOWN = 0;public static final int ACTION_UP = 1;public static final int ACTION_MOVE = 2;// 获取坐标public final float getX() { ... }public final float getY() { ... }// 创建事件public static MotionEvent obtain(long downTime, long eventTime,int action, float x, float y, int metaState) { ... }
}

1.3 权限要求

1.3.1 普通权限

<uses-permission android:name="android.permission.INTERNET" />

1.3.2 特殊权限

<!-- 注入事件权限 -->
<uses-permission android:name="android.permission.INJECT_EVENTS" tools:ignore="ProtectedPermissions" />

注意：INJECT_EVENTS是系统权限，普通应用无法获取，需要系统签名或root权限。

第二部分：基础模拟操作实现

2.1 按键模拟

2.1.1 单个按键操作

// 模拟返回键
public void simulateBackKey() {long downTime = SystemClock.uptimeMillis();long eventTime = SystemClock.uptimeMillis();KeyEvent downEvent = new KeyEvent(downTime, eventTime, KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK, 0);KeyEvent upEvent = new KeyEvent(downTime, eventTime, KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK, 0);try {Instrumentation inst = new Instrumentation();inst.sendKeySync(downEvent);inst.sendKeySync(upEvent);} catch (Exception e) {e.printStackTrace();}
}

2.1.2 组合按键操作

// 模拟Home键长按(打开最近任务)
public void simulateLongPressHome() {long downTime = SystemClock.uptimeMillis();long eventTime = SystemClock.uptimeMillis() + 1000; // 长按1秒KeyEvent downEvent = new KeyEvent(downTime, downTime, KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HOME, 0);KeyEvent upEvent = new KeyEvent(downTime, eventTime, KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HOME, 0);try {Instrumentation inst = new Instrumentation();inst.sendKeySync(downEvent);Thread.sleep(1000); // 保持按下状态inst.sendKeySync(upEvent);} catch (Exception e) {e.printStackTrace();}
}

2.2 触摸模拟

2.2.1 单点触摸

// 模拟在(x,y)位置的点击
public void simulateTap(int x, int y) {long downTime = SystemClock.uptimeMillis();long eventTime = SystemClock.uptimeMillis();// 按下动作MotionEvent downEvent = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_DOWN, x, y, 0);// 抬起动作MotionEvent upEvent = MotionEvent.obtain(downTime, eventTime + 100, MotionEvent.ACTION_UP, x, y, 0);try {Instrumentation inst = new Instrumentation();inst.sendPointerSync(downEvent);inst.sendPointerSync(upEvent);} catch (Exception e) {e.printStackTrace();} finally {downEvent.recycle();upEvent.recycle();}
}

2.2.2 滑动操作

// 模拟从(startX,startY)滑动到(endX,endY)
public void simulateSwipe(int startX, int startY, int endX, int endY) {long downTime = SystemClock.uptimeMillis();// 按下动作MotionEvent downEvent = MotionEvent.obtain(downTime, downTime, MotionEvent.ACTION_DOWN, startX, startY, 0);// 移动动作MotionEvent moveEvent = MotionEvent.obtain(downTime, downTime + 50, MotionEvent.ACTION_MOVE, startX + (endX-startX)/2, startY + (endY-startY)/2, 0);// 抬起动作MotionEvent upEvent = MotionEvent.obtain(downTime, downTime + 100, MotionEvent.ACTION_UP, endX, endY, 0);try {Instrumentation inst = new Instrumentation();inst.sendPointerSync(downEvent);inst.sendPointerSync(moveEvent);inst.sendPointerSync(upEvent);} catch (Exception e) {e.printStackTrace();} finally {downEvent.recycle();moveEvent.recycle();upEvent.recycle();}
}

2.3 文本输入模拟

2.3.1 单个字符输入

// 模拟输入单个字符
public void simulateCharInput(char c) {try {Instrumentation inst = new Instrumentation();inst.sendCharacterSync(KeyEvent.KEYCODE_A); // 替换为对应字符的键码} catch (Exception e) {e.printStackTrace();}
}

2.3.2 字符串输入

// 模拟输入字符串
public void simulateTextInput(String text) {try {Instrumentation inst = new Instrumentation();inst.sendStringSync(text);} catch (Exception e) {e.printStackTrace();}
}

第三部分：高级模拟操作技术

3.1 多指触控模拟

3.1.1 MotionEvent多指支持

安卓通过指针索引(pointer index)和指针ID(pointer id)支持多点触控：

• 每个触摸点有唯一的pointer id
• pointer index是当前活动触摸点的索引

3.1.2 双指缩放实现

// 模拟双指缩放手势
public void simulatePinchZoom(int centerX, int centerY, float scaleFactor) {long downTime = SystemClock.uptimeMillis();int startDistance = 100; // 初始两指距离int endDistance = (int)(startDistance * scaleFactor);// 第一指按下MotionEvent downEvent1 = MotionEvent.obtain(downTime, downTime,MotionEvent.ACTION_DOWN,centerX - startDistance/2,centerY, 0);// 第二指按下MotionEvent downEvent2 = MotionEvent.obtain(downTime, downTime,MotionEvent.ACTION_POINTER_DOWN |(1 << MotionEvent.ACTION_POINTER_INDEX_SHIFT),centerX + startDistance/2,centerY, 0);// 移动过程List<MotionEvent> moveEvents = new ArrayList<>();for (int i = 1; i <= 5; i++) {float fraction = i / 5f;int currentDistance = (int)(startDistance + (endDistance - startDistance) * fraction);long eventTime = downTime + i * 50;MotionEvent moveEvent = MotionEvent.obtain(downTime, eventTime,MotionEvent.ACTION_MOVE,centerX - currentDistance/2,centerY, 0);moveEvent.setLocation(centerX + currentDistance/2, centerY);moveEvents.add(moveEvent);}// 抬起第二指MotionEvent upEvent2 = MotionEvent.obtain(downTime, downTime + 300,MotionEvent.ACTION_POINTER_UP |(1 << MotionEvent.ACTION_POINTER_INDEX_SHIFT),centerX + endDistance/2,centerY, 0);// 抬起第一指MotionEvent upEvent1 = MotionEvent.obtain(downTime, downTime + 350,MotionEvent.ACTION_UP,centerX - endDistance/2,centerY, 0);try {Instrumentation inst = new Instrumentation();inst.sendPointerSync(downEvent1);inst.sendPointerSync(downEvent2);for (MotionEvent event : moveEvents) {inst.sendPointerSync(event);event.recycle();}inst.sendPointerSync(upEvent2);inst.sendPointerSync(upEvent1);} catch (Exception e) {e.printStackTrace();} finally {downEvent1.recycle();downEvent2.recycle();upEvent1.recycle();upEvent2.recycle();}
}

3.2 复杂手势模拟

3.2.1 画圆手势

// 模拟画圆手势
public void simulateCircleGesture(int centerX, int centerY, int radius) {long downTime = SystemClock.uptimeMillis();int steps = 36; // 圆的细分段数double angleStep = 2 * Math.PI / steps;// 按下动作MotionEvent downEvent = MotionEvent.obtain(downTime, downTime,MotionEvent.ACTION_DOWN,centerX + radius,centerY, 0);// 移动动作序列List<MotionEvent> moveEvents = new ArrayList<>();for (int i = 1; i <= steps; i++) {double angle = angleStep * i;int x = (int)(centerX + radius * Math.cos(angle));int y = (int)(centerY + radius * Math.sin(angle));long eventTime = downTime + i * 20;MotionEvent moveEvent = MotionEvent.obtain(downTime, eventTime,MotionEvent.ACTION_MOVE,x, y, 0);moveEvents.add(moveEvent);}// 抬起动作MotionEvent upEvent = MotionEvent.obtain(downTime, downTime + steps * 20,MotionEvent.ACTION_UP,centerX + radius,centerY, 0);try {Instrumentation inst = new Instrumentation();inst.sendPointerSync(downEvent);for (MotionEvent event : moveEvents) {inst.sendPointerSync(event);event.recycle();}inst.sendPointerSync(upEvent);} catch (Exception e) {e.printStackTrace();} finally {downEvent.recycle();upEvent.recycle();}
}

3.3 无障碍服务实现模拟操作

3.3.1 无障碍服务配置

AndroidManifest.xml配置：

<service android:name=".MyAccessibilityService"android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"><intent-filter><action android:name="android.accessibilityservice.AccessibilityService" /></intent-filter><meta-data android:name="android.accessibilityservice"android:resource="@xml/accessibility_service_config" />
</service>

res/xml/accessibility_service_config.xml:

<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"android:description="@string/accessibility_service_description"android:accessibilityEventTypes="typeAllMask"android:accessibilityFlags="flagRequestFilterKeyEvents"android:canRequestFilterKeyEvents="true"android:canPerformGestures="true"android:settingsActivity="com.example.android.accessibility.ServiceSettingsActivity" />

3.3.2 手势分发实现

public class MyAccessibilityService extends AccessibilityService {@Overridepublic void onAccessibilityEvent(AccessibilityEvent event) {// 处理无障碍事件}@Overridepublic void onInterrupt() {// 服务中断处理}// 分发手势public boolean dispatchGesture(int x, int y) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {Path path = new Path();path.moveTo(x, y);GestureDescription.Builder builder = new GestureDescription.Builder();builder.addStroke(new GestureDescription.StrokeDescription(path, 0, 50));return dispatchGesture(builder.build(), null, null);}return false;}// 更复杂的多指手势public boolean dispatchMultiFingerGesture(List<Point> points) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {GestureDescription.Builder builder = new GestureDescription.Builder();for (Point point : points) {Path path = new Path();path.moveTo(point.x, point.y);builder.addStroke(new GestureDescription.StrokeDescription(path, 0, 100));}return dispatchGesture(builder.build(), null, null);}return false;}
}

第四部分：实用案例与应用场景

4.1 自动化测试应用

4.1.1 测试用例录制与回放

public class TestRecorder {private List<InputEvent> recordedEvents = new ArrayList<>();private boolean isRecording = false;public void startRecording() {recordedEvents.clear();isRecording = true;}public void stopRecording() {isRecording = false;}public void recordEvent(InputEvent event) {if (isRecording) {recordedEvents.add(event);}}public void replayEvents() {try {Instrumentation inst = new Instrumentation();for (InputEvent event : recordedEvents) {if (event instanceof KeyEvent) {inst.sendKeySync((KeyEvent)event);} else if (event instanceof MotionEvent) {inst.sendPointerSync((MotionEvent)event);}Thread.sleep(50); // 事件间延迟}} catch (Exception e) {e.printStackTrace();}}
}

4.2 游戏辅助工具

4.2.1 连点器实现

public class AutoClicker {private boolean isClicking = false;private int clickInterval = 500; // 毫秒private int targetX, targetY;private Thread clickingThread;public void startClicking(int x, int y) {targetX = x;targetY = y;isClicking = true;clickingThread = new Thread(() -> {while (isClicking) {simulateTap(targetX, targetY);try {Thread.sleep(clickInterval);} catch (InterruptedException e) {break;}}});clickingThread.start();}public void stopClicking() {isClicking = false;if (clickingThread != null) {clickingThread.interrupt();}}public void setClickInterval(int interval) {clickInterval = interval;}
}

4.3 远程控制实现

4.3.1 通过Socket接收指令

public class RemoteControlService extends Service {private static final int PORT = 12345;private ServerSocket serverSocket;private boolean isRunning = true;@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {new Thread(() -> {try {serverSocket = new ServerSocket(PORT);while (isRunning) {Socket clientSocket = serverSocket.accept();handleClient(clientSocket);}} catch (IOException e) {e.printStackTrace();}}).start();return START_STICKY;}private void handleClient(Socket clientSocket) {try {BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));String inputLine;while ((inputLine = in.readLine()) != null) {processCommand(inputLine);}} catch (IOException e) {e.printStackTrace();}}private void processCommand(String command) {String[] parts = command.split(",");switch (parts[0]) {case "TAP":int x = Integer.parseInt(parts[1]);int y = Integer.parseInt(parts[2]);simulateTap(x, y);break;case "SWIPE":int startX = Integer.parseInt(parts[1]);int startY = Integer.parseInt(parts[2]);int endX = Integer.parseInt(parts[3]);int endY = Integer.parseInt(parts[4]);simulateSwipe(startX, startY, endX, endY);break;case "KEY":int keyCode = Integer.parseInt(parts[1]);simulateKey(keyCode);break;}}@Overridepublic void onDestroy() {isRunning = false;try {if (serverSocket != null) {serverSocket.close();}} catch (IOException e) {e.printStackTrace();}super.onDestroy();}@Nullable@Overridepublic IBinder onBind(Intent intent) {return null;}
}

第五部分：优化与进阶

5.1 性能优化

5.1.1 事件批量发送

public void sendEventsBulk(List<InputEvent> events) {try {Instrumentation inst = new Instrumentation();// 开始批量Method beginBatchMethod = Instrumentation.class.getDeclaredMethod("beginBatch");beginBatchMethod.setAccessible(true);beginBatchMethod.invoke(inst);// 发送事件for (InputEvent event : events) {if (event instanceof KeyEvent) {inst.sendKeySync((KeyEvent)event);} else if (event instanceof MotionEvent) {inst.sendPointerSync((MotionEvent)event);}}// 结束批量Method endBatchMethod = Instrumentation.class.getDeclaredMethod("endBatch");endBatchMethod.setAccessible(true);endBatchMethod.invoke(inst);} catch (Exception e) {e.printStackTrace();}
}

5.1.2 事件时间戳优化

// 更精确的事件时间戳控制
public void simulatePreciseTap(int x, int y, long duration) {long downTime = SystemClock.uptimeMillis();long upTime = downTime + duration;MotionEvent downEvent = MotionEvent.obtain(downTime, downTime,MotionEvent.ACTION_DOWN,x, y, 0);MotionEvent upEvent = MotionEvent.obtain(downTime, upTime,MotionEvent.ACTION_UP,x, y, 0);try {Instrumentation inst = new Instrumentation();inst.sendPointerSync(downEvent);Thread.sleep(duration);inst.sendPointerSync(upEvent);} catch (Exception e) {e.printStackTrace();} finally {downEvent.recycle();upEvent.recycle();}
}

5.2 兼容性处理

5.2.1 不同安卓版本适配

public void simulateClickCompat(int x, int y) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {// 使用无障碍服务APIif (myAccessibilityService != null) {myAccessibilityService.dispatchGesture(x, y);}} else {// 使用InstrumentationsimulateTap(x, y);}
}

5.2.2 不同设备分辨率适配

public Point convertCoordinates(int x, int y) {DisplayMetrics metrics = Resources.getSystem().getDisplayMetrics();int screenWidth = metrics.widthPixels;int screenHeight = metrics.heightPixels;// 假设原始坐标是基于1080x1920设计的float scaleX = screenWidth / 1080f;float scaleY = screenHeight / 1920f;return new Point((int)(x * scaleX), (int)(y * scaleY));
}

5.3 安全与权限管理

5.3.1 动态权限申请

private static final int REQUEST_INJECT_PERMISSION = 1;public void checkAndRequestPermissions(Activity activity) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {if (!Settings.canDrawOverlays(activity)) {Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,Uri.parse("package:" + activity.getPackageName()));activity.startActivityForResult(intent, REQUEST_INJECT_PERMISSION);}}
}@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {if (requestCode == REQUEST_INJECT_PERMISSION) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {if (Settings.canDrawOverlays(this)) {// 权限已授予} else {// 权限被拒绝}}}
}

结语
