無障礙點擊核心代碼

// 自定義無障礙服務類，繼承自Android系統的AccessibilityService
public class MyAccessibilityService extends AccessibilityService {// 當系統產生無障礙事件時的回調方法（如界面變化、焦點切換等）@Overridepublic void onAccessibilityEvent(AccessibilityEvent event) {// 這里可以監聽屏幕內容變化（默認空實現）}// 當系統需要中斷服務時的回調方法（如用戶關閉服務）@Overridepublic void onInterrupt() {// 服務中斷處理邏輯（默認空實現）}// 核心方法：通過坐標執行點擊操作public void clickAtPoint(int x, int y) {// 構建手勢描述對象GestureDescription.Builder builder = new GestureDescription.Builder();// 創建路徑對象（用于定義手勢軌跡）Path path = new Path();// 將路徑起點移動到目標坐標path.moveTo(x, y);// 在同一個坐標點畫線（形成點擊手勢）path.lineTo(x, y); // 單點點擊的核心邏輯// 構建手勢描述：// 添加手勢筆畫（Stroke），參數說明：// path - 手勢路徑// 0    - 開始時間（單位：毫秒，0表示立即開始）// 50   - 持續時間（單位：毫秒，50ms足夠完成點擊）GestureDescription gesture = builder.addStroke(new GestureDescription.StrokeDescription(path, 0, 50)).build();// 執行手勢操作dispatchGesture(gesture, new GestureResultCallback() {// 手勢成功完成的回調@Overridepublic void onCompleted(GestureDescription gestureDescription) {super.onCompleted(gestureDescription);Log.d("TAG", "點擊完成"); // 日志記錄點擊成功}// 手勢被取消的回調@Overridepublic void onCancelled(GestureDescription gestureDescription) {super.onCancelled(gestureDescription);Log.e("TAG", "點擊取消"); // 日志記錄點擊失敗}}, null); // 第三個參數Handler可設置為null（使用默認線程）}

無障礙滑動核心代碼

public class MyAccessibilityService extends AccessibilityService {// 核心方法：通過坐標執行滑動操作public void swipe(int startX, int startY, int endX, int endY, int durationMs) {GestureDescription.Builder builder = new GestureDescription.Builder();Path path = new Path();// 定義滑動路徑path.moveTo(startX, startY);     // 起點path.lineTo(endX, endY);          // 終點// 構建手勢描述：// 參數說明：// path - 滑動路徑// 0    - 開始時間（0表示立即開始）// durationMs - 滑動持續時間（毫秒）GestureDescription gesture = builder.addStroke(new GestureDescription.StrokeDescription(path, 0, durationMs)).build();// 執行滑動操作dispatchGesture(gesture, new GestureResultCallback() {@Overridepublic void onCompleted(GestureDescription gestureDescription) {super.onCompleted(gestureDescription);Log.d("TAG", "滑動完成");}@Overridepublic void onCancelled(GestureDescription gestureDescription) {super.onCancelled(gestureDescription);Log.e("TAG", "滑動取消");}}, null);}

通過無障礙服務在指定坐標 (100,100) 處粘貼剪貼板內容 "你好"?

public class MyAccessibilityService extends AccessibilityService {// 核心方法：在指定坐標粘貼文本public void pasteTextAtPoint(int x, int y, String text) {// 1. 模擬點擊坐標以聚焦輸入框clickAtPoint(x, y);// 2. 等待輸入框獲得焦點（建議300-500ms延遲）new Handler(Looper.getMainLooper()).postDelayed(() -> {// 3. 獲取當前窗口根節點AccessibilityNodeInfo rootNode = getRootInActiveWindow();if (rootNode == null) return;// 4. 查找焦點所在的輸入控件AccessibilityNodeInfo focusedNode = rootNode.findFocus(AccessibilityNodeInfo.FOCUS_INPUT);if (focusedNode != null) {// 5. 設置剪貼板內容setClipboardText(text);// 6. 執行粘貼操作Bundle args = new Bundle();args.putInt(AccessibilityNodeInfo.ACTION_ARGUMENT_MOVEMENT_GRANULARITY_INT, AccessibilityNodeInfo.MOVEMENT_GRANULARITY_CHARACTER);focusedNode.performAction(AccessibilityNodeInfo.ACTION_PASTE, args);// 或者直接設置文本（API 21+）// Bundle setTextArgs = new Bundle();// setTextArgs.putCharSequence(//     AccessibilityNodeInfo.ACTION_ARGUMENT_SET_TEXT_CHARSEQUENCE, //     text// );// focusedNode.performAction(//     AccessibilityNodeInfo.ACTION_SET_TEXT, //     setTextArgs// );}rootNode.recycle();}, 500); // 延遲500ms確保焦點穩定}// 點擊坐標方法private void clickAtPoint(int x, int y) {Path path = new Path();path.moveTo(x, y);GestureDescription gesture = new GestureDescription.Builder().addStroke(new StrokeDescription(path, 0, 50)).build();dispatchGesture(gesture, null, null);}// 設置剪貼板內容private void setClipboardText(String text) {ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);ClipData clip = ClipData.newPlainText("label", text);clipboard.setPrimaryClip(clip);}

無障礙返回

public class MyAccessibilityService extends AccessibilityService {// 核心方法：模擬返回鍵public void performBack() {// 調用系統級返回操作boolean isSuccess = performGlobalAction(GLOBAL_ACTION_BACK);Log.d("TAG", "返回操作結果: " + (isSuccess ? "成功" : "失敗"));}@Overridepublic void onAccessibilityEvent(AccessibilityEvent event) {// 可監聽返回操作后的界面變化（可選）}@Overridepublic void onInterrupt() {// 中斷處理}
}

無障礙回到主頁

public class MyAccessibilityService extends AccessibilityService {// 核心方法：模擬Home鍵public void pressHomeButton() {boolean isSuccess = performGlobalAction(GLOBAL_ACTION_HOME);Log.d("TAG", "Home鍵操作結果: " + (isSuccess ? "成功" : "失敗"));}@Overridepublic void onAccessibilityEvent(AccessibilityEvent event) {// 可監聽界面變化（可選）}@Overridepublic void onInterrupt() {// 中斷處理}
