Is it possible to use adb commands to click on a view by finding its ID?

Question

Suppose I have an app (in debug/release build , made by me or not), which has an ID for a specific view.

Is it possible to call adb command to click on this view?

Answer 1

Using what @pskink explained in the comments above, here's how I achieved this:

First, I ran this command:

adb shell dumpsys activity top

Then, I used this code to parse it:

public class ViewCoordsGetter {
    public static Rect getViewBoundyingBox(String viewIdStr) {
        final List<String> viewHierarchyLog = //result of the command
        for (int i = 0; i < viewHierarchyLog.size(); ++i) {
            String line = viewHierarchyLog.get(i);
            if (line.contains(":id/" + viewIdStr + "}")) {
                Rect result = getBoundingBoxFromLine(line);
                if (i == 0)
                    return result;
                int currentLineStart = getStartOfViewDetailsInLine(line);
                for (int j = i - 1; j >= 0; --j) {
                    line = viewHierarchyLog.get(j);
                    if ("View Hierarchy:".equals(line.trim()))
                        break;
                    int newLineStart = getStartOfViewDetailsInLine(line);
                    if (newLineStart < currentLineStart) {
                        final Rect boundingBoxFromLine = getBoundingBoxFromLine(line);
                        result.left += boundingBoxFromLine.left;
                        result.right += boundingBoxFromLine.left;
                        result.top += boundingBoxFromLine.top;
                        result.bottom += boundingBoxFromLine.top;
                        currentLineStart = newLineStart;
                    }
                }
                return result;
            }
        }
        return null;
    }

    private static int getStartOfViewDetailsInLine(String s) {
        int i = 0;
        while (true)
            if (s.charAt(i++) != ' ')
                return --i;
    }

    private static Rect getBoundingBoxFromLine(String line) {
        int endIndex = line.indexOf(',', 0);
        int startIndex = endIndex - 1;
        while (!Character.isSpaceChar(line.charAt(startIndex - 1)))
            --startIndex;
        int left = Integer.parseInt(line.substring(startIndex, endIndex));
        startIndex = endIndex + 1;
        endIndex = line.indexOf('-', startIndex);
        endIndex = line.charAt(endIndex - 1) == ',' ? line.indexOf('-', endIndex + 1) : endIndex;
        int top = Integer.parseInt(line.substring(startIndex, endIndex));
        startIndex = endIndex + 1;
        endIndex = line.indexOf(',', startIndex);
        int right = Integer.parseInt(line.substring(startIndex, endIndex));
        startIndex = endIndex + 1;
        //noinspection StatementWithEmptyBody
        for (endIndex = startIndex + 1; Character.isDigit(line.charAt(endIndex)); ++endIndex)
            ;
        int bot = Integer.parseInt(line.substring(startIndex, endIndex));
        return new Rect(left, top, right, bot);
    }
}
