如何检测具有 wrap_content 属性的 TextView 的宽度？

Question

I have a layout with element TextView

<TextView android:textColor="#ffffff" android:text="18 августа"
                    android:id="@+id/program_day1" android:layout_gravity="center"
                    android:textSize="18sp" android:textStyle="bold"
                    android:layout_height="wrap_content" android:layout_width="wrap_content"
                    android:layout_weight="1" android:gravity="center" />

How can I detect the real size (and margins) of this in the onStart (or other) event? Now it shows "-2" values

Answer 1

try with myTextView.getPaint().measureText(myTextViewtext) it didn't return the size of the view but the size of the text,hope it could help you

Answer 2

Views don't get height or width until they are actually drawn on screen.

Try to show the width in the onSizeChanged function. Check if a real size will be shown. Use getwidth .

Answer 3

Apart from that, you can use TextView.getWidth() and Textview.getHeight() to get w/h and
LayoutParams lp = (LayoutParams) TextView.getLayoutParams(); to get margin values
