android清空 list,list - How to clear cache Android - Stack Overflow

I need to find a way how to clear the data which my application stores in cache.Basically I am using Fedor's ( Lazy load of images in ListView ) lazy list implementation and I want to clear the cache automatically when I have for example 100 images loaded.Any ideas how to do that?

EDIT:

Code :

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

list=(ListView)findViewById(R.id.list);

adapter=new LazyAdapter(this, mStrings);

list.setAdapter(adapter);

deleteCache(this);

adapter.notifyDataSetChanged();

}

public static void deleteCache(Context context) {

try {

File dir = context.getCacheDir();

if (dir != null && dir.isDirectory()) {

deleteDir(dir);

}

} catch (Exception e) {}

}

public static boolean deleteDir(File dir) {

if (dir != null && dir.isDirectory()) {

String[] children = dir.list();

for (int i = 0; i < children.length; i++) {

boolean success = deleteDir(new File(dir, children[i]));

if (!success) {

return false;

}

}

}

return dir.delete();

}
