Right Alignment for Spinner via Java (Not via XML)

Question

Spinners need to be Right aligned on the Screen

I tried to use everything like setGravity and other, Nothing worked.

I tried to search also a lot for this Right alignment, everywhere solution is available in XML format but NOT in Java format. Can someone Please help :)

Code

        final LinearLayout lm = (LinearLayout) findViewById(R.id.linearLayout1);
        LinearLayout ll = new LinearLayout(this);
        ll.setOrientation(LinearLayout.HORIZONTAL);

        final Spinner spinner = new Spinner(this);
        spinner.setOnItemSelectedListener(this);
        ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, categories);
        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(dataAdapter);
        spinner.setEnabled(false);
        ll.addView(spinner);
        lm.addView(ll);

Abir : Now its showing this.

I think this should solve your problem:

    final LinearLayout lm = (LinearLayout) findViewById(R.id.linearLayout1);
    LinearLayout ll = new LinearLayout(this);
    ll.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
    ll.setGravity(Gravity.RIGHT);
    ll.setOrientation(LinearLayout.HORIZONTAL);

    final Spinner spinner = new Spinner(this);
    spinner.setOnItemSelectedListener(this);
    ArrayAdapter<String> dataAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, categories);
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(dataAdapter);
    spinner.setEnabled(false);
    ll.addView(spinner);
    lm.addView(ll);

You should set your dynamic linearLayout's width and height. and then set its gravity to RIGHT. Then your spinner will be aligned on the right side of the view.

Thanks for the reply. :) But now everything is going to Right. I think because we setGravity for Linearlayout, It has shiifted everthing. – Bharat Mar 09 '16 at 08:55
Please find the new image @top. I need only Spinner to Right most side. – Bharat Mar 09 '16 at 08:57
I thought you only had one child as Spinner. – Abir Hasan Shawon Mar 09 '16 at 09:00

I have 3 ...1CheckBox, 1TextView & 1 Spinner. I want only Spinner Right Aligned. Can you please help? :) – Bharat Mar 09 '16 at 09:02
So you want a CheckBox, then a TextView after that a Spinner. Now my question is, Do you want the spinner right after the TextView or aligned at the end of the view? – Abir Hasan Shawon Mar 09 '16 at 09:18
Spinner is already after TextView. I want only Spinner aligned at the end of the view. i.e. After textView, there will be some space and then Spinner will Right Aligned. – Bharat Mar 09 '16 at 09:36
i have provided another answer. check it out, i hope it solves your problem :) – Abir Hasan Shawon Mar 09 '16 at 09:40
Thanks for your help. I will check and let you know :) – Bharat Mar 09 '16 at 09:42

I hope this will work for you. It's a bit complex, cause it has multiple nested views. But this will solve the issue and i think you will get the view you want.

    final LinearLayout lm = (LinearLayout) findViewById(R.id.linearLayout1);
    LinearLayout ll = new LinearLayout(this);
    ll.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
    ll.setWeightSum(1);
    ll.setOrientation(LinearLayout.HORIZONTAL);


    final CheckBox box = new CheckBox(this);
    box.setLayoutParams(new LinearLayout.LayoutParams(0, ViewGroup.LayoutParams.WRAP_CONTENT, .1f));

    final TextView tv = new TextView(this);
    tv.setLayoutParams(new LinearLayout.LayoutParams(0, ViewGroup.LayoutParams.WRAP_CONTENT, .3f));
    tv.setText("STD_MOBILE");

    LinearLayout l2 = new LinearLayout(this);
    l2.setLayoutParams(new LinearLayout.LayoutParams(0, ViewGroup.LayoutParams.WRAP_CONTENT, .6f));
    l2.setGravity(Gravity.RIGHT);
    l2.setOrientation(LinearLayout.HORIZONTAL);


    final Spinner spinner = new Spinner(this);
    spinner.setOnItemSelectedListener(this);
    ArrayAdapter<String> dataAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, categories);
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(dataAdapter);
    spinner.setEnabled(false);


    l2.addView(spinner);

    ll.addView(box);
    ll.addView(tv);
    ll.addView(l2);
    lm.addView(ll);

I have used weight to specify the exact space for your childViews. Then made the Spinner's parent layout's gravity to right.

its working Abir. Thanks for all the effort you have put in. :) — Bharat, Mar 09 '16 at 10:42

You have to use a custom view here to give alignment to the Spinner values. Create a CustomView like this answer has created and add android:gravity to the TextView as right.

Set the CustomView to your adapter using

adapter.setDropDownViewResource(android.R.layout.your_custom_created_view);
