最近更新后无法使用按钮打开带有LOCK_MODE_LOCKED_CLOSED的抽屉

Question

setDrawerListener

我以前有这行代码禁用滑动手势，但顶部切换按钮打开抽屉。我发现在支持库的最新更新后，它不再正常工作。我无法通过切换按钮或滑动手势打开抽屉。我需要取消注释线以打开抽屉。

有谁知道需要改变什么？

我还将addDrawerListener更改为public abstract class BaseActivity extends AppCompatActivity { protected DrawerLayout mDrawer; ActionBarDrawerToggle actionBarDrawerToggle; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_base); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); mDrawer = (DrawerLayout) findViewById(R.id.navigation_drawer); setSupportActionBar(toolbar); getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setHomeButtonEnabled(true); actionBarDrawerToggle = new ActionBarDrawerToggle(this,mDrawer,toolbar,0,0); mDrawer.addDrawerListener(actionBarDrawerToggle); // Disable drawer's swiping function mDrawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED); LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View contentView = inflater.inflate(getLayoutResource(), null, false); FrameLayout mainContent = (FrameLayout) findViewById(R.id.main_content); mainContent.addView(contentView, 0); inflateDrawerItem(); } public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { int id = item.getItemId(); if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } } ，因为前者已折旧。

Answer 1

尝试聆听工具栏的Navigation onClick listener

并检查单击切换按钮的时间，然后调用openDrawer / closeDrawer http://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html#openDrawer(int)

Answer 2

您可以设置监听工具栏以及单击切换按钮时。这是一个参考。

Answer 3

使用mDrawer.setDrawerLockMode（DrawerLayout.LOCK_MODE_UNLOCKED）;
