Pinch gestures

[Manasa Muchchatti]

Hi,

I need to automate Solo to do pinch(Two finger gesture) in my test cases for some scenarios. Can anyone know how to simulate it.?

Thanks

Hello,

I think currently it is not possible.

Please share information, if you find the way.

Best regards,

Yahor

Hi,

I need to do a three finger tap on the device screen to perform some functionality on my android application. Can i simulate this with Robotium?

Hi,

I've managed to do so using the code below. Of course you need to determine the start points and measure of pinching that suits your own app:

private void moveZoomTilt() {

long downTime = SystemClock.uptimeMillis();

// event time MUST be retrieved only by this way!

long eventTime = SystemClock.uptimeMillis();

Instrumentation inst = getInstrumentation();

View view = solo.getView(R.id.crop_window);

Rect viewRect = new Rect();

view.getGlobalVisibleRect(viewRect);

//set Overall coords and properties of gestures

PointerCoords[] pointCoords = new PointerCoords[2];

pointCoords[0] = new PointerCoords();

pointCoords[0].pressure = 1;

pointCoords[0].size = 1;

pointCoords[1] = new PointerCoords();

pointCoords[1].pressure = 1;

pointCoords[1].size = 1;

PointerProperties[] props = new PointerProperties[2];

props[0] = new PointerProperties();

props[0].id = 0;

props[0].toolType = MotionEvent.TOOL_TYPE_FINGER;

props[1] = new PointerProperties();

props[1].id = 1;

props[1].toolType = MotionEvent.TOOL_TYPE_FINGER;

//Pinch

// Set start point of fingers. Both in the vertical middle, the first on 1/3 of the horizantal scale, the second on 2/3

float finger2XStart = viewRect.left + (viewRect.width() / 3);

float finger2YStart = viewRect.top + (viewRect.height() / 2);

float finger3XStart = viewRect.left + ((viewRect.width() / 3)*2);

float finger3YStart = viewRect.top + (viewRect.height() / 2);

// finger tracks

float[] tracking2X = { -15, -30, -45, -30, -15, 0, 15, 30, 45, 30, 15, 0, -15, -30 };

float[] tracking2Y = { 0,0,0,0,0,0,0,0,0,0,0,0,0,0 };

float[] tracking3X = { 15, 30, 45, 30, 15, 0, -15, -30, -45, -30, -15, 0, 15, 30 };

float[] tracking3Y = { 0,0,0,0,0,0,0,0,0,0,0,0,0,0 };

// set Start Coordinates 

pointCoords[0].x = finger2XStart;   

pointCoords[0].y = finger2YStart; 

pointCoords[1].x = finger3XStart;   

pointCoords[1].y = finger3YStart; 

try {

// first finger down

event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_DOWN, 1, props, pointCoords, 0, 0, 1, 1, 0, 0, 0, 0);

inst.sendPointerSync(event);

// second finger down

event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_POINTER_2_DOWN, 2, props, pointCoords, 0, 0, 1, 1, 0, 0, 0, 0);

inst.sendPointerSync(event);

// move fingers (in j steps)

for(int j = 0; j < tracking2X.length; j++) {

eventTime = SystemClock.uptimeMillis() + 50;

pointCoords[0].x = finger2XStart + tracking2X[j];

pointCoords[0].y = finger2YStart + tracking2Y[j];

pointCoords[1].x = finger3XStart + tracking3X[j];

pointCoords[1].y = finger3YStart + tracking3Y[j];

event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_MOVE, 2, props, pointCoords, 0, 0, 1, 1, 0, 0, 0, 0);

inst.sendPointerSync(event);

}

eventTime = SystemClock.uptimeMillis();

// second finger up

event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_POINTER_2_UP, 2, props, pointCoords, 0, 0, 1, 1, 0, 0, 0, 0);

inst.sendPointerSync(event);

// first finger up

event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_UP, 1, props, pointCoords, 0, 0, 1, 1, 0, 0, 0, 0);

inst.sendPointerSync(event);

} catch (Exception exception) {

Log.e("pinchError", exception.getMessage());

}

Hi Jores,

I tried to implement the above code, my view after this stmnt View view = solo.getView(R.id.crop_window); is null.. so it didnt do anything.

I use that to first get the ID and secondly the bounds of my view (named "crop_window"). I only use it to get the location of where i should start my pinch gesture. You can decide any way you want where you want to start your "fingers" for your pinch gesture, and use these points in the finger2XStart (etc.) variables.

When i browsed for 'Error inflating class' i found out that this error occurs when the view size is big.. So any idea...
