java - Android UIAutomator 长按设备

Question

我想在指定时间长按指定点。不幸的是，类中没有像长按这样的方法:UiDevice我可能可以编写自己的方法，如下所示:

private void longClick(int x, int y, long time) {
    android.graphics.Point point = new android.graphics.Point(x, y);
    android.graphics.Point[] points = new android.graphics.Point[2];
    points[0] = point;
    points[1] = point;
    getUiDevice().swipe(points, time / 5); // according to documentation, each step lasts 5ms
}

或者使用反射并调用 longTap:

private void longClick(int x, int y) {
    Field mUiAutomationBridgeField = getUiDevice().getClass().getDeclaredField("mUiAutomationBridge");
    mUiAutomationBridgeField.setAccessible(true);
    Object mUiAutomationBridge = mUiAutomationBridgeField.get(getUiDevice());
    Field mInteractionControllerField = mUiAutomationBridge.getClass().getDeclaredField("mInteractionController");
    mInteractionControllerField.setAccessible(true);
    Object mInteractionController = mInteractionControllerField.get(mUiAutomationBridge);
    Method longTap = mInteractionController.getClass().getDeclaredMethod("longTap", int.class, int.class);
    longTap.setAccessible(true);
    longTap.invoke(mInteractionController, x, y);
}

但是它不是令人满意的解决方案，知道如何做得更好吗？为什么他们会错过这种方法？

Answer 1

getUiDevice().getInstance().swipe(x, y, x, y, 400);

起点和终点相同。然后就可以模拟uiDevice长按了。
