How to Click Invisible Android UI Elements with UiAutomator by Calculating Coordinates

While learning UiAutomator, the author encountered UI elements whose bounds were reported as [0,0][0,0], making them impossible to click directly, especially in complex hierarchies such as the JD app coupon page.

To work around this, the author proposes using the size of a previously‑found control to calculate a reliable click coordinate and then performing the click on either the left or right half of the target element.

public void getUiObjectByResoureIdAndclickRightHalf(String id) throws UiObjectNotFoundException {
    // Get control size
    Rect sss = getUiObjextByResourceId(id).getBounds();
    // Compute offset to the right half (center + width/4)
    clickPiont(sss.centerX() + sss.width() / 4, sss.centerY());
}

public void getUiObjectByResoureIdAndclickLeftHalf(String id) throws UiObjectNotFoundException {
    // Get control size
    Rect sss = getUiObjextByResourceId(id).getBounds();
    // Compute offset to the left half (center - width/4)
    clickPiont(sss.centerX() - sss.width() / 4, sss.centerY());
}

The two helper methods first retrieve the Rect of the UI object via getUiObjextByResourceId(id).getBounds(), then calculate a point offset from the rectangle’s center by a quarter of its width, and finally invoke clickPiont(x, y) to simulate the tap.
