我试图让这个onScrollListener适用于API版本低于23，当我尝试这样做，我得到我在标题中提到的错误设置onScrollChangeListener时：java.lang.NoClassDefFoundError上recyclerview
这里我发现了一个错误：
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
list.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
//If scrolled at last then
if (isLastItemDisplaying(recyclerView)) {
// Calling the method get data again
getData();
}
}
});
} else {
// here i'm getting an error
list.setOnScrollChangeListener(new RecyclerView.OnScrollChangeListener() {
@Override
public void onScrollChange(View v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
// If scrolled at last then
if (isLastItemDisplaying(list)) {
// Calling the method get data again
getData();
}
}
});
}
我能multidex支持和编译'com.android.support:multidex:1.0.1'但仍然我得到一个错误。我也有类扩展这样的应用程序初始化MultiDex：
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
