Question

Can someone please tell me how to set the android:layout_weight and android:layout_width XML attributes in code for dynamically created views?

Reference: XML Table layout? Two EQUAL-width rows filled with equally width buttons?

Answer 1

Use ViewGroup.LayoutParams.

LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, 
                                   LayoutParams.WRAP_CONTENT);
myview.setLayoutParams(lp);

You can also specify fixed pixel sizes in the constructor, instead of the constants. But fixed pixels are a bad idea on android due to the variety of devices.

You can calculate the pixels from a dp size though, which is ok:

float pixels = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 
                                         10, getResources.getDisplayMetrics());

(Here: convert 10dp to a pixel value)
