Android view layout_width - how to change programmatically?
android, android-layout
Solution
I believe your question is to change only width of view dynamically, whereas above methods will change layout properties completely to new one, so I suggest to getLayoutParams() from view first, then set width on layoutParams, and finally set layoutParams to the view, so following below steps to do the same.
View view = findViewById(R.id.nutrition_bar_filled);
LayoutParams layoutParams = view.getLayoutParams();
layoutParams.width = newWidth;
view.setLayoutParams(layoutParams);
Problem
This is my view, and I wish to change layout_width to "10dip". How do I do so programmatically? Note, this is not a LinearLayout, it's a View. ``` <View android:id="@+id/nutrition_bar_filled" android:background="@drawable/green_rectangle" android:layout_height="30dp" android:layout_width="50dp"/> ``` I know about LayoutParams. How do I use it to set the width to 10dip?
