【问题描述】：
发布我的问题here too.
初学者..我正在做一个学校地图应用程序。
首先我有 4 个按钮的背景（level3、level4、level5、level6）。
我尝试单击所有按钮，通常单击其中的 3 个后，下一个将崩溃。（每个级别按钮进入关卡地图，单击房间图像按钮，我将进入画廊图像切换器）
我在每个级别的地图中至少有 5 个ImageSwitchers，所以总共有超过 20 个ImageSwitcher 画廊。
我使用Drawable 而不是Bitmap 完成了所有工作。我有很多图片（因为它是一张学校地图，显示我学校的所有照片，以及所有这些背景和ImageButton）
我做了一些研究，有问题的是那些使用位图的人。一些可以解决的方法是system.gc();和bitmap.recycle（虽然不太清楚怎么用）
在我的主要背景中 - starttour.java
public class StartTour extends Activity {
private SoundManager mSoundManager;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ttour);
mSoundManager = new SoundManager();
mSoundManager.initSounds(getBaseContext());
mSoundManager.addSound(1, R.raw.beep);
//play music
final MediaPlayer mPlayer = MediaPlayer.create(this, R.raw.jazz);
mPlayer.start();
final Button button = (Button) findViewById(R.id.back);
button.setOnClickListener(new Button.OnClickListener() {
// Implement the OnClickListener callback
public void onClick(View v) {
// do something when the button is clicked
startActivity(new Intent("android.com.Android"));
mSoundManager.playSound(1);
mPlayer.stop();
}
});
final Button button1 = (Button) findViewById(R.id.level3);
button1.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
// Perform action on click
startActivity(new Intent("android.com.Lvl3"));
mSoundManager.playSound(1);
mPlayer.stop();
}
});
final Button button2 = (Button) findViewById(R.id.level4);
button2.setOnClickListener(new Button.OnClickListener() {

// Perform action on click
startActivity(new Intent("android.com.Lvl4"));
mSoundManager.playSound(1);
mPlayer.stop();
}
});
final Button button3 = (Button) findViewById(R.id.level5);
button3.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
// Perform action on click
startActivity(new Intent("android.com.Lvl5"));
mSoundManager.playSound(1);
mPlayer.stop();
}
});

button4.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
// Perform action on click
startActivity(new Intent("android.com.Lvl6"));
mSoundManager.playSound(1);
mPlayer.stop();
}
});

如果我先点击任何按钮并进入关卡地图，当我查看图像切换器图片时它会崩溃。

如果有人可以提供帮助真的很感激..谢谢
PS：我的应用中有大量图片。我在每个级别至少有 5 个ImageSwitcher 画廊，所以在我的应用程序中加起来有 20 多个图像切换器。
【问题讨论】：
-
您至少可以将帖子的文本复制并粘贴到堆栈溢出中
-
Protip：不要在代码中复制行号。我们有语法高亮；使用code formatting button 格式化您的代码。您似乎使用该按钮来显示错误消息，但使用引用按钮来显示您的代码。
