Question

我正在使用Recycler View创建导航抽屉。早些时候它正在工作，现在突然我得到验证错误。

致命的例外：主要过程：com.tanmay.androidsupport，PID：18435 java.lang.VerifyError的： COM / tanmay / androidsupport /视图/适配器/ DrawerAdapter 在 com.tanmay.androidsupport.view.activities.HomeActivity.onCreate（HomeActivity.java:75）在android.app.Activity.performCreate（Activity.java:5264）在 android.app.Instrumentation.callActivityOnCreate（Instrumentation.java:1088）在 android.app.ActivityThread.performLaunchActivity（ActivityThread.java:2302）在 android.app.ActivityThread.handleLaunchActivity（ActivityThread.java:2390）在android.app.ActivityThread.access $ 800（ActivityThread.java:151）在 android.app.ActivityThread $ H.handleMessage（ActivityThread.java:1321）在android.os.Handler.dispatchMessage（Handler.java:110）在android.os.Looper.loop（Looper.java:193）在android.app.ActivityThread.main（ActivityThread.java:5292） at java.lang.reflect.Method.invokeNative（Native Method）在java.lang.reflect.Method.invoke（Method.java:515）在 com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run（ZygoteInit.java:828）在com.android.internal.os.ZygoteInit.main（ZygoteInit.java:644）在dalvik.system.NativeStart.main（本地方法）

这是我的抽屉适配器 -

public class DrawerAdapter extends RecyclerView.Adapter<DrawerAdapter.ViewHolder> {

static final int TYPE_HEADER = 0;
static final int TYPE_ITEM = 1;
Context context;
String[] navTitles;

public DrawerAdapter(Context context, String Titles[]) {
    navTitles = Titles;
    this.context = context;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    if (viewType == TYPE_ITEM) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.drawer_item, parent, false);
        ViewHolder vhItem = new ViewHolder(v, viewType);
        return vhItem;
    } else if (viewType == TYPE_HEADER) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.drawer_header, parent, false);
        ViewHolder vhHeader = new ViewHolder(v, viewType);
        return vhHeader;
    }
    return null;
}

@Override
public void onBindViewHolder(ViewHolder holder, final int position) {
    if (holder.Holderid == 1) {
        holder.drawerItem.setText(navTitles[position - 1]);
    } else {

    }
}

@Override
public int getItemCount() {
    return navTitles.length + 1;
}

@Override
public int getItemViewType(int position) {
    if (isPositionHeader(position))
        return TYPE_HEADER;

    return TYPE_ITEM;
}

private boolean isPositionHeader(int position) {
    return position == 0;
}

public static class ViewHolder extends RecyclerView.ViewHolder {
    int Holderid;
    TextView drawerItem;

    public ViewHolder(View itemView, int ViewType) {
        super(itemView);
        if (ViewType == TYPE_ITEM) {
            drawerItem = (TextView) itemView.findViewById(R.id.drawer_option);
            Holderid = 1;
        } else {
            Holderid = 0;
        }
    }
}

}

看起来你编译的是一个不同于你在运行时使用的库。
