java - 一个 ImageButton 可以工作，其他的则崩溃应用程序

Question

我在一个 Activity 中有 6 个 ImageButton，第一个可以正常工作，但在设备上单击其他按钮时，应用程序会崩溃。 我对其余的 ImageButtons 使用了相同的代码 - 我错过了什么吗？

布局文件看起来很完美。使用此代码。我用过R.id:

// Load the ImageView that will host the animation and
// set its background to our AnimationDrawable XML resource.
ImageView blackRotButton = (ImageView)findViewById(R.id.BlackRotAnim);
blackRotButton.setBackgroundResource(R.drawable.black_rot_anim);

// Get the background, which has been compiled to an AnimationDrawable object.
AnimationDrawable diseaseButton1Animation = (AnimationDrawable) blackRotButton.getBackground();

// Start the animation (looped playback by default).
diseaseButton1Animation.start();

// Load the ImageView that will host the animation and
// set its background to our AnimationDrawable XML resource.
ImageView bacterialBrownSpotButton = (ImageView)findViewById(R.id.BacterialBrownSpotAnim);
bacterialBrownSpotButton.setBackgroundResource(R.drawable.bacterial_brown_spot_anim);

// Get the background, which has been compiled to an AnimationDrawable object.
AnimationDrawable diseaseButton2Animation = (AnimationDrawable) bacterialBrownSpotButton.getBackground();

// Start the animation (looped playback by default).
diseaseButton2Animation.start();

// Load the ImageView that will host the animation and
// set its background to our AnimationDrawable XML resource.
ImageView budBlasttButton = (ImageView)findViewById(R.id.BudBlastAnim);
budBlasttButton.setBackgroundResource(R.drawable.bud_blast_anim);

// Get the background, which has been compiled to an AnimationDrawable object.
AnimationDrawable diseaseButton3Animation = (AnimationDrawable) budBlasttButton.getBackground();

// Start the animation (looped playback by default).
diseaseButton3Animation.start();

// Load the ImageView that will host the animation and
// set its background to our AnimationDrawable XML resource.
ImageView rotButton = (ImageView)findViewById(R.id.RotAnim);
rotButton.setBackgroundResource(R.drawable.rot_anim);

// Get the background, which has been compiled to an AnimationDrawable object.
AnimationDrawable diseaseButton4Animation = (AnimationDrawable) rotButton.getBackground();

// Start the animation (looped playback by default).
diseaseButton4Animation.start();

// Load the ImageView that will host the animation and
// set its background to our AnimationDrawable XML resource.
ImageView sunBurnButton = (ImageView)findViewById(R.id.SunBurnAnim);
sunBurnButton.setBackgroundResource(R.drawable.sun_burn_anim);

// Get the background, which has been compiled to an AnimationDrawable object.
AnimationDrawable diseaseButton5Animation = (AnimationDrawable) sunBurnButton.getBackground();

// Start the animation (looped playback by default).
diseaseButton5Animation.start();

// Load the ImageView that will host the animation and
// set its background to our AnimationDrawable XML resource.
ImageView virusButton = (ImageView)findViewById(R.id.VirusAnim);
virusButton.setBackgroundResource(R.drawable.virus_anim);

// Get the background, which has been compiled to an AnimationDrawable object.
AnimationDrawable diseaseButton6Animation = (AnimationDrawable) virusButton.getBackground();

// Start the animation (looped playback by default).
diseaseButton6Animation.start();}
