Question

我有点陷入这个任务。我有一个应用程序显示嵌入谷歌地图的主要片段，现在我想用另一个片段替换它，当用户点击抽屉菜单列表中的发送按钮时显示一些图表。

当我点击发送应用程序卡住时，给我讨厌的“应用程序无响应”。但是，如果我将android：name字段更改为相同的地图片段，它将正常工作并显示地图。

我启动地图片段

的主要活动代码段

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    if (toolbar != null) {
        setSupportActionBar(toolbar);
    }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.activity_main);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();


    mapsFragment = new MapsFragment();
    getSupportFragmentManager().beginTransaction()
            .add(R.id.maincontainer,mapsFragment)
            .commit();

    navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

}

主要活动代码段，我在其中启动图表片段

    public boolean onNavigationItemSelected(MenuItem item) {
        // Handle navigation view item clicks here.
        Snackbar snackbar;
        Fragment fragment = null;
        switch(item.getItemId()){
            case R.id.nav_manage:
                snackbar = Snackbar
                        .make(coordinatorLayout, "manage", Snackbar.LENGTH_LONG);
                snackbar.show();
                break;
            case R.id.nav_share:
                snackbar = Snackbar
                        .make(coordinatorLayout, "share", Snackbar.LENGTH_LONG);
                snackbar.show();
                break;
            case R.id.nav_send:
                snackbar = Snackbar
                        .make(coordinatorLayout, "send", Snackbar.LENGTH_LONG);
                snackbar.show();
                fragment = new ChartsFragment();
                break;
            case R.id.nav_view:
                snackbar = Snackbar
                        .make(coordinatorLayout, "view", Snackbar.LENGTH_LONG);
                snackbar.show();
                break;
        }
        if(fragment != null){
            getSupportFragmentManager().beginTransaction()
                    .replace(R.id.maincontainer,fragment)
                    .commit();
        }
        // Highlight the selected item has been done by NavigationView
        item.setChecked(true);
        // Set action bar title
        //setTitle(item.getTitle());
        DrawerLayout drawer = (DrawerLayout)
findViewById(R.id.activity_main);
        drawer.closeDrawer(GravityCompat.START);
        return true;
    }

MapsFragment onCreate

 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_maps, container, false);
        SupportMapFragment mMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
        mMapFragment.getMapAsync(this);
        mContext = getActivity();
        return rootView;
    }

ChartsFragment onCreate

 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_charts, container, false);
    return rootView;
}

我已经尝试替换

机器人：名称= “com.fabio.gis.geotag.ChartsFragment”

与

类= “com.fabio.gis.geotag.ChartsFragment”

没有任何改变。

提前感谢您的支持。我意识到我是Android的初学者，也许我正在为一个愚蠢的新手错误而苦苦挣扎。

过了一会儿，它仍留在ANR中，它给了我以下的堆栈跟踪错误
