java– 在ImageButton中使用gif

概述如果有人点击它,如何在ImageButton的src中切换动画GIF图像和静态图像？在onCreate()我有这个aButton3=(ImageButton)findViewById(R.id.imageButton3);SharedPreferencessharedPreferences=getSharedPreferences("NAME",Context.MODE_PRIVATE);Booleane=sharedPrefere

如果有人点击它,如何在Imagebutton的src中切换动画gif图像和静态图像？

在onCreate()我有这个

abutton3 = (Imagebutton) findVIEwByID(R.ID.imagebutton3);SharedPreferences sharedPreferences = getSharedPreferences("name", Context.MODE_PRIVATE);Boolean e = sharedPreferences.getBoolean("clicked3", false);

当有人单击Imagebutton时会执行以下 *** 作

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();    }}

解决方法:

我想出了一个方法,它工作得非常好.
首先我定义了全局变量

AnimationDrawable myFrameAnimation;

然后在onCreate()中我用一个变量定义了该按钮.

abutton3 = (Imagebutton) findVIEwByID(R.ID.imagebutton3);

然后为该按钮创建一个onClickListener()方法.

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();            }        }    });

这里“trans”是一个纯粹透明的图像,因此单击之前我之前的图像不会显示.

在“frame_animation”中,我定义了图像的所有帧以获得完美的动画图像

<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" />
