java - 使用 android 支持库 v23.4.0 时抽屉导航未打开

Question

大家好，我正在开发一个使用旧抽屉导航方法的应用程序。当我将 'com.android.support:appcompat-v7:23.1.1' 更新为 'com.android.support:appcompat-v7:23.4.0' 时，我的抽屉导航未打开。

我调试了代码并查找已弃用的项目，但找不到任何错误代码或消息。一切正常，但抽屉导航未打开。这是我的代码。提前致谢。

MainActivity.class

public class MainActivity extends AppCompatActivity implements NavigationDrawerFragment.NavigationDrawerCallbacks, TapuInterface.IAuthorization {

Answer 1

抽屉已锁。

改变

mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

至

mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
