我使用Espresso测试我的应用程序,我需要在RecyclerView中测试拖放行为。不幸的是,我在Espresso中看不到任何拖动()动作,我错过了什么?
答案 0 :(得分:1)
我没有找到任何Espresso
拖动选项。只有swipeUp()
,swipeDown()
,swipeLwft()
,swipeRight()
,在这种情况下可能没用。
此外,在Google网上论坛中存在无法解答的问题:https://groups.google.com/forum/#!msg/android-test-kit-discuss/X3TDJBUT4Ho/OJAOkTOoxGcJ
虽然还有Espresso MotionEvents
类sendMovement()
方法,但我还没有尝试过。
使用以下代码:
public static void drag(Instrumentation inst, float fromX, float toX, float fromY,
float toY, int stepCount) {
long downTime = SystemClock.uptimeMillis();
long eventTime = SystemClock.uptimeMillis();
float y = fromY;
float x = fromX;
float yStep = (toY - fromY) / stepCount;
float xStep = (toX - fromX) / stepCount;
MotionEvent event = MotionEvent.obtain(downTime, eventTime,
MotionEvent.ACTION_DOWN, x, y, 0);
inst.sendPointerSync(event);
for (int i = 0; i < stepCount; ++i) {
y += yStep;
x += xStep;
eventTime = SystemClock.uptimeMillis();
event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_MOVE, x, y, 0);
inst.sendPointerSync(event);
}
eventTime = SystemClock.uptimeMillis();
event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_UP, x, y, 0);
inst.sendPointerSync(event);
inst.waitForIdleSync();
}
