HI all:
sourcefile:android-sdk-linux/sources/android-15/android/test/
TouchUtils.java
public static int dragViewToX(InstrumentationTestCase test, View
v, int gravity, int toX) {
int[] xy = new int[2];
getStartLocation(v, gravity, xy);
final int fromX = xy[0];
final int fromY = xy[1];
int deltaX = fromX - toX;
drag(test, fromX, toX, fromY, fromY, deltaX);
return deltaX;
}
public static void drag(InstrumentationTestCase test, float fromX,
float toX, float fromY,
float toY, int stepCount) {
Instrumentation inst = test.getInstrumentation();
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);
inst.waitForIdleSync();
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);
inst.waitForIdleSync();
}
eventTime = SystemClock.uptimeMillis();
event = MotionEvent.obtain(downTime, eventTime,
MotionEvent.ACTION_UP, x, y, 0);
inst.sendPointerSync(event);
inst.waitForIdleSync();
}
If the fromX is samller than toX, deltaX is negative, so stepCount
is negative too, It seems never move.
Am i make a bad decision? Please help me!
