How to set dynamically the width of button according to its text content in android?

Question

I want to have button size according to the text content. For example, if size of text is about 4 letters then width of button be should big enough to adjust 4 letters only.Here is My Code:

layout = (LinearLayout) dialog.getCustomView().findViewById(R.id.layoutTags);
layout.setOrientation(LinearLayout.VERTICAL);  //Can also be done in xml by android:orientation="vertical"
layout.setWeightSum(1);
layout.removeAllViews();
layout.invalidate();
float rowneed = ((float) count1 / 5);
k = 0;
for (int i = 0; i < ceil(rowneed); i++) {
    LinearLayout row = new LinearLayout(getContext());
    row.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
    row.removeAllViews();
    for (int j = 0; j < 5; j++) {
        btnTag = new Button(getContext());
        btnTag.setHeight(15);
        btnTag.setWidth(1);
        btnTag.setMinimumWidth(155);
        btnTag.setMinimumHeight(135);

        if (k < count1) {
            btnTag.setText(filteredTags.get(k).gettagName());
            btnTag.setId(k);
            k++;
            btnTag.setVisibility(View.VISIBLE);

        } else {
            btnTag.setVisibility(View.INVISIBLE);
        }
        Log.e("count", " " + k + " " + count1 + " " + ceil(rowneed) + " " + edtTag.getText().toString());
        btnTag.setTextSize(7);
        btnTag.setGravity(0);

        row.addView(btnTag);
    }
    layout.addView(row);
}

Why not have wrap_content for width and height in xml instead? — Shashank Udupa, Mar 20 '17 at 06:18

@ShashankUdupa ,because we are creating multiple buttons dynamically. thank you – — Priya singh, Mar 20 '17 at 06:31
@RavindraShekhawat thank you for the link. But ,I want to resize a button not a text. Any Help! — Priya singh, Mar 20 '17 at 06:39
You just need to change view use button instead of textview throughout code. Atleast try first there is no such function provided by android to resize view dynamically on basis of text size so you will have to put efforts ..:-) — Ravindra Shekhawat, Mar 20 '17 at 06:42
try `btnTag.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));` — Naz141, Mar 20 '17 at 06:48
Did you remove these `btnTag.setHeight(15); btnTag.setWidth(1); btnTag.setMinimumWidth(155); btnTag.setMinimumHeight(135); btnTag.setGravity(0);` and use the above code? — Naz141, Mar 20 '17 at 08:33

Set LayoutParams in java

ViewGroup.LayoutParams p = button.getLayoutParams();
p.width= ViewGroup.LayoutParams.WRAP_CONTENT;
button.setLayoutParams(p);

Use this :

button.setLayoutParams(new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT,
1.0f));
