I have four buttons in a LinearLayout. I want to set the width of these Button as 25%. How to do that?

To change the width at runtime use the below code:

button_1=findViewById(R.id.button_1);
button_1.setLayoutParams(new LinearLayout.LayoutParams(100,100));

but you want to set the width of 4 buttons as 25%.

Now for this You can pass the weight attribute into LayoutParams.

The syntax for runtime equal weight is:

LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT, weight in float);
yourView.setLayoutParams(param);

You can use below code to change width of buttons at runtime:

Button button1=findViewById(R.id.button1);
Button button2=findViewById(R.id.button2);
Button button3=findViewById(R.id.button3);
Button button4=findViewById(R.id.button4);
LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT,1.0f);
button1.setLayoutParams(param);
button2.setLayoutParams(param);
button3.setLayoutParams(param);
button4.setLayoutParams(param);

I hope its work for you.
