How to toggle between an animated GIF image and a static one in ImageButton's src when someone clicks it?
in onCreate()
I have this
aButton3 = (ImageButton) findViewById(R.id.imageButton3);
SharedPreferences sharedPreferences = getSharedPreferences("NAME", Context.MODE_PRIVATE);
Boolean e = sharedPreferences.getBoolean("clicked3", false);
The following gets executed when someone clicks the ImageButton
public void buttonClick2(View v) {
SharedPreferences sharedPreferences = getSharedPreferences("NAME", Context.MODE_PRIVATE);
Boolean d = sharedPreferences.getBoolean("clicked2", false);
if (!d) {
toggleSound.start();
aButton2.setImageResource(R.drawable.on);
sharedPreferences = getSharedPreferences("NAME", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("clicked2", true);
editor.commit();
}
if(d){
toggleSound.start();
aButton2.setImageResource(R.drawable.off);
sharedPreferences = getSharedPreferences("NAME", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor = sharedPreferences.edit();
editor.putBoolean("clicked2", false);
editor.commit();
}
}
I figured out a way and it was working absolutely fine. First I defined global variable
AnimationDrawable myFrameAnimation;
Then in onCreate() i defined the button with a variable.
aButton3 = (ImageButton) findViewById(R.id.imageButton3);
Then create a onClickListener() method for that button.
aButton3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
SharedPreferences sharedPreferences = getSharedPreferences("NAME", Context.MODE_PRIVATE);
Boolean e = sharedPreferences.getBoolean("clicked3", false);
if (!e) {
toggleSound.start();
aButton3.setImageResource(R.drawable.trans);
aButton3.setBackgroundResource(R.drawable.frame_animation);
myFrameAnimation=(AnimationDrawable) aButton3.getBackground();
myFrameAnimation.start();
aButton4.setImageResource(R.drawable.reg1);
def=1;
count=1;
sharedPreferences = getSharedPreferences("NAME", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("clicked3", true);
editor.commit();
editor.putInt("clicked5", def);
editor.commit();
editor.putInt("clicked4", count);
editor.commit();
}
if(e){
toggleSound.start();
aButton3.setBackgroundResource(R.drawable.frame_animation2);
myFrameAnimation=(AnimationDrawable) aButton3.getBackground();
myFrameAnimation.start();
aButton3.setImageResource(R.drawable.newoff);
aButton4.setImageResource(R.drawable.reg0);
count=0;
def=0;
sharedPreferences = getSharedPreferences("NAME", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor = sharedPreferences.edit();
editor.putBoolean("clicked3", false);
editor.commit();
editor.putInt("clicked4", count);
editor.commit();
editor.putInt("clicked6", def);
editor.commit();
}
}
});
Here "trans" is a purely transparent image so that my previous image before click does not show after click.
In "frame_animation" I defined all the frames of the image to get a perfect animated image
<animation-list android:oneshot="false" xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/pic1" android:duration="5" />
<item android:drawable="@drawable/pic2" android:duration="5" />
<item android:drawable="@drawable/pic3" android:duration="5" />
<item android:drawable="@drawable/pic4" android:duration="5" />
<item android:drawable="@drawable/pic5" android:duration="5" />
<item android:drawable="@drawable/pic6" android:duration="5" />
<item android:drawable="@drawable/pic7" android:duration="5" />
<item android:drawable="@drawable/pic8" android:duration="5" />
<item android:drawable="@drawable/pic9" android:duration="5" />
