java - Android: Button does not change color when pressed -


i have made custom_button.xml in drawable folder when buttons pressed, , default. looks follows:

<selector xmlns:android="http://schemas.android.com/apk/res/android">  <item android:state_pressed="true" >     <shape>         <gradient             android:startcolor="@color/red"             android:endcolor="@color/light_red"             android:angle="270" />         <corners             android:radius="5dp" />     </shape> </item>  <item>     <shape>         <gradient             android:startcolor="@color/light_purple"             android:endcolor="@color/purple"             android:angle="270" />         <corners             android:radius="5dp" />     </shape> </item>

my buttons fine when not pressed, shows default purple button. when press it, not change red button should when state_pressed.

in activity_main.xml, buttons defined follows:

<button     android:id="@+id/button1"     android:layout_width="0dp"     android:layout_height="fill_parent"     android:layout_weight="1"     android:background="@drawable/custom_button"     android:layout_margin="5dp"/>

i'm using nested linearlayout if makes difference.

please let me know if there's i've missed!

edit: found out source of problem, not sure how fix it. when remove these following listeners createlisteners, buttons change color should.

 b1.setontouchlistener(new view.ontouchlistener() {         @override         public boolean ontouch(view v, motionevent event) {             if(event.getaction() == motionevent.action_down) {                 int beat = getbeat(1);                 m1 = mediaplayer.create(mainactivity.this, beat);                 m1.start();                 m1.setlooping(true);                 return true;             } else if (event.getaction() == motionevent.action_up) {                 m1.release();             }             return false;         }     });

what it's doing plays song long button pressed. how interfere button color?

it seems ontouchlistener() doesn't work correctly selector. have change background manually in action_down , action_up.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
