Implement long Press and drag in Android Automation test

In the Android application automation process, you'll see a scene that needs to be long pressed and dragged, such as a UC browser, long pressed on a navigation icon to make it removable, and then move it to another place, swapping it with other navigation icons, with a drag in the Robotium (float FromX, float ToX, float fromY, float toy,int stepcount) method, but because the drag does not have a long press this step, therefore cannot make the application in the movable state, cannot complete such common and simple operation.

Drag method source code implementation is as follows:

public void drag (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, FromX, FromY, 0);

try {

Inst.sendpointersync (event);

catch (SecurityException ignored) {}

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);

try {

Inst.sendpointersync (event);

catch (SecurityException ignored) {}

}

Eventtime = Systemclock.uptimemillis ();

event = Motionevent.obtain (Downtime, eventtime, Motionevent.action_up,tox, ToY, 0);

try {

Inst.sendpointersync (event);

catch (SecurityException ignored) {}

}

Can be seen in fact, through the Motionevent action_down analog screen operation, action_move simulation gestures on the screen, action_up analog gesture left the screen, thus completing the entire drag process, And in fact the various click-Class methods in Robotium are also done by simulating different gestures.

Therefore, in order to complete the long press and drag operation, as long as the Action_down, stay for a period of time can simulate long press operation.

Delay one second, simulate long press operation

Eventtime = Systemclock.uptimemillis () + 1000;

Xstop added 10 point coordinates, the view coordinates obtained need to make a little adjustment according to the application actual situation

Moved a little bit again, not to do so can not activate the applied state of the test, causing the view to move back to the original position
