我使用Mike Penz的MaterialDrawer实现了一个 MiniDrawer。

它工作正常，但是当我尝试用另一个片段替换框架的内容时，内容会被替换，但旧内容仍保留在那里，并且两个元素都停留在屏幕上。

您的代码显示您有一个FrameLayout托管TextView. FrameLayout用于并且将Crossfader是内容区域。

当您用片段替换内容区域时，您尝试替换不存在的id. 据我所见，content_frame您的布局中没有。

我强烈建议您FrameLayout在crossfade_content其中放置另一个，稍后将替换为片段。

编辑

fragment_container您应该在没有子代的FrameLayoutid中创建一个crossfade_content，然后您只需设置第一个片段，然后您可以稍后用不同的片段替换这个片段。

所以你会有一些这样的代码：

result = new Drawer()
    .withActivity(this)
    .withToolbar(mToolbar)
    . withFireOnInitialOnClick(true)
    .addDrawerItems(
            new PrimaryDrawerItem().withName("FragmentA").withIdentifier(1),
          new PrimaryDrawerItem().withName("FragmentB").withIdentifier(2)
    )
    .withOnDrawerItemClickListener(new Drawer.OnDrawerItemClickListener() {
        @Override
        public void onItemClick(View view, int position, IDrawerItem drawerItem) {
              if(drawerItem != null) {
                  Fragment f = null;
                  switch(drawerItem.getIdentifier) {
                  case 1:
                    f = FragmentA.newInstance();
                  break;
                  case 2:
                    f = FragmentA.newInstance();

                  break;
                  }

                  if (drawerItem instanceof Nameable) {
                    mToolbar.setTitle(MainActivity.this.getString(((Nameable) drawerItem).getNameRes()));
                  }
              }
            }
        }
    }).build();

这将在启动时设置第一个片段，因为我们设置withFireOnInitialOnClick(true)了将为第一个选定的片段触发。然后用新选定项目的正确片段替换它。onItemClick所以你在监听器中有整个片段逻辑
