条件下按钮用法的文本值

Question

I'm trying to make condition where I wanto compare text value of button but it always doesn't match...

<Button android:layout_width="90dp" android:layout_height="40dp" android:gravity="center" android:text="+" android:id="@+id/baton1" android:layout_gravity="left|center_vertical" />

I've tried to print out the value and it shows like "[+]"...

if (btn.toString().equals("[+]")) {

Answer 1

I assume you did the necessary stuff to reach the button object from the class file.

As I know, You need to use getText() method while getting the text property of the objects.

So, you should do something like that;

if (btn.getText().equals("+"))
