android : using weight to textviews for linearlayout in java file

Question

Is there any way of generating weight to textviews for linearlayout in java file.

This is the code im using but its not alligned properly

java file:

LinearLayout afternoonLayout = (LinearLayout) findViewById(R.id.afternoonLayoutId);

    if(afternoonSession !=null && afternoonSession.size() >= 0){

        TextView txtAfternoon = new TextView(this);
        txtAfternoon.setText("Afternoon");
        txtAfternoon.setTextSize(22);
        txtAfternoon.setGravity(Gravity.LEFT);
        txtAfternoon.setTypeface(null, Typeface.BOLD);
        txtAfternoon.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

        if(afternoonSession.has("Vitals")){

            txtAfternoonVitals = new TextView(this);
            txtAfternoonVitals.setText("Vitals " + "- " + "                      " + afternoonSession.get("Vitals").toString().replace("\"", ""));
            txtAfternoonVitals.setTextSize(16);
            txtAfternoonVitals.setGravity(Gravity.START);
            txtAfternoonVitals.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

        }else{
            txtAfternoonVitals = new TextView(this);
            txtAfternoonVitals.setText("Vitals " + "- " + "                      " + "Not Done");
            txtAfternoonVitals.setTextColor(Color.RED);
            txtAfternoonVitals.setTextSize(16);
            txtAfternoonVitals.setGravity(Gravity.START);
            txtAfternoonVitals.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

        }

        if(afternoonSession.has("Lunch")){

            txtAfternoonLunch = new TextView(this);
            txtAfternoonLunch.setText("Lunch " + "- " + "                     " + afternoonSession.get("Lunch").toString().replace("\"", ""));
            txtAfternoonLunch.setTextSize(16);
            txtAfternoonLunch.setGravity(Gravity.START);
            txtAfternoonLunch.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

        }else{
            txtAfternoonLunch = new TextView(this);
            txtAfternoonLunch.setText("Lunch " + "- " + "                     " + "Not Done");
            txtAfternoonLunch.setTextColor(Color.RED);
            txtAfternoonLunch.setTextSize(16);
            txtAfternoonLunch.setGravity(Gravity.START);
            txtAfternoonLunch.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

        }

        if(afternoonSession.has("Oral Medication")){

            txtAfternoonOral = new TextView(this);
            txtAfternoonOral.setText("Oral Medication " + "- " + "    " + afternoonSession.get("Oral Medication").toString().replace("\"", ""));
            txtAfternoonOral.setTextSize(16);
            txtAfternoonOral.setGravity(Gravity.START);
            txtAfternoonOral.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

        }else{
            txtAfternoonOral = new TextView(this);
            txtAfternoonOral.setText("Oral Medication " + "- " + "    " + "Not Done");
            txtAfternoonOral.setTextColor(Color.RED);
            txtAfternoonOral.setTextSize(16);
            txtAfternoonOral.setGravity(Gravity.START);
            txtAfternoonOral.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

        }

        afternoonLayout.setPadding(10,10,10,10);
        afternoonLayout.addView(txtAfternoon);
        afternoonLayout.addView(txtAfternoonVitals);
        afternoonLayout.addView(txtAfternoonLunch);
        afternoonLayout.addView(txtAfternoonOral);


    }

I have alligned the code using blankspace, this is not the proper way of doing since im getting different allignment in different mobile versions

Output needed:

  Afternoon
  vitals            02:00pm 
  Lunch             03:00pm
  Oral Medication   04:00pm

But i am getting unalligned textview in different mobile versions.Is there any way of adding weight to java file.Since im doing string concatination i am unable to use weights

This is the output i am getting

enter image description here

Why don't you use recyclerview for this purpose and create a proper row with weights that will be easy for this requirement ? — Faraz Ahmed, Mar 07 '17 at 12:09
You can also assign weights to each textView and just ensure that the width and height is both set to match_parent — Janwilx72, Mar 07 '17 at 12:09
Add third parameter to setLayoutParams like this - txtAfternoon.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT,1f)); — Ragini, Mar 07 '17 at 12:12
@FarazAhmed : need to change logic as well, so its better to implement using this format — , Mar 07 '17 at 12:13
I think the guy needs more of a monospace font adjustment, than adjustment of the weights of the view. — H.A.H., Mar 07 '17 at 12:16

You can set layoutweight and weightSum from java code like below:

LinearLayout layout = (LinearLayout)findViewById(R.id.afternoonLayoutId);
layout.setWeightSum(10F);
LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) layout.getLayoutParams(); 
//you can  create new LayoutParams too ...
layoutParams.weight = 0.5f;
txtAfternoonVitals = new TextView(layout.getContext());
txtAfternoon .setLayoutParams(layoutParams);

Weights can adjust the textview to be with different heights. I seriously doubt that this is what you want. If I understand your "align with blankspace", you are looking how to apply monospace font, so that the hours are aligned. Good luck.
