Window displayWidth and displayHeight invalid on device rotate

[pingpongboss]

Maybe caching the displayWidth and displayHeight isn't the way to go. https://github.com/pingpongboss/StandOut/blob/master/library/src/wei/mark/standout/ui/Window.java#L80

Rotating the screen should also check the window size and bounds to make sure they fit in the screen if need be.

here's my workaround for this (for classes extending StandOutWindow):

public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

            if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        checkForEdges(111, null);
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        checkForEdges(111, null);
    }
}

private StandOutLayoutParams checkForEdges(int id, Window window) {
    if (window == null) {
        window = getWindow(id);
    }
    Drawable d = getResources().getDrawable(R.drawable.ic_nos);
    int w = d.getIntrinsicWidth();
    int h = d.getIntrinsicHeight();
    Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
    DisplayMetrics metrics = new DisplayMetrics();
    display.getMetrics(metrics);
    int widthPixels = metrics.widthPixels;
    int heightPixels = metrics.heightPixels;
    Log.i("A919Tool", "widthPixels: " + widthPixels + ", heightPixels: " + heightPixels);

    StandOutLayoutParams solp = new StandOutLayoutParams(id, w, h);
    if (window.getLayoutParams().x < 0) {
        solp.x = 0;
        solp.y = window.getLayoutParams().y;
        window.setLayoutParams(solp);
    }
    if (window.getLayoutParams().x > widthPixels-w) {
        solp.x = widthPixels-w;
        solp.y = window.getLayoutParams().y;
        window.setLayoutParams(solp);
    }
    if (window.getLayoutParams().x == heightPixels-w) { // like Gravity.RIGHT
        solp.x = widthPixels-w;
        solp.y = window.getLayoutParams().y;
        window.setLayoutParams(solp);
    }
    if (window.getLayoutParams().y < 0) {
        solp.y = 0;
        solp.x = window.getLayoutParams().x;
        window.setLayoutParams(solp);
    }
    if (window.getLayoutParams().y > heightPixels-h-getStatusBarHeight()) {
        solp.y = heightPixels-h-getStatusBarHeight();
        solp.x = window.getLayoutParams().x;
        window.setLayoutParams(solp);
    }

    if (window.getLayoutParams().y == widthPixels-h-getStatusBarHeight()) { //like Gravity.BOTTOM
        solp.y = heightPixels-h-getStatusBarHeight();
        solp.x = window.getLayoutParams().x;
        window.setLayoutParams(solp);
    }

saveX = window.getLayoutParams().x;
    saveY = window.getLayoutParams().y;
    window.edit().setPosition(saveX, saveY).commit();

    this.sPreferences = PreferenceManager.getDefaultSharedPreferences(this.getApplicationContext());
    Editor edtr = this.sPreferences.edit();
    edtr.putInt("saveX", saveX);
    edtr.putInt("saveY", saveY);
    edtr.commit();
    return solp;
}

Does not seem to work. BTW, can we know what this drawable "ic_nos" refers to ?

[viju85]

Never mind. found another way to fix this.

I also find the way to rotate window. Currently window only allow for portrait orientation. I can capture orientation changing by overriding onConfigurationChanged method.But Xposition never change.

[yikhinzaw]

Now i can do screen rotation without doing any brocast receiver for orientation changing.I only update window.setPosition method. In that method , you need to define displaywidth and height to get latest width and height.

That is what I did as well. On Oct 23, 2013 12:58 AM, "yikhinzaw" [email protected] wrote:

i'm facing the same problem but still i've not found a solution by myself. rotating the screen do not update screen width/height so i can not wander a window around. someone have shared the code somewhere??? thanks

[yikhinzaw]

You need to update in Standout Library. In Library, there has setPosition method in winodw.java. You need to called Display Height and width in those method. as follows,

private Editor setPosition(int x, int y, boolean skip) {

        DisplayMetrics metrics = mContext.getResources()
                .getDisplayMetrics();
        displayHeight = (int) (metrics.heightPixels - 25 * metrics.density);
        displayHeight = metrics.heightPixels;

                                  //others are the same as original code.

    }

tankyou. i'vecopied it in getlayoutparams so w/h are always up to date

@yikhinzaw thanks, you code works if correct what i think is a mistake. Booth lines are display height, not width. The code below makes it work as it should.

  DisplayMetrics metrics = mContext.getResources()
            .getDisplayMetrics();
    displayHeight = (int) (metrics.heightPixels - 25 * metrics.density);
    displayWidth = metrics.widthPixels;

                              //others are the same as original code.

}
