安卓 "No view found for id for fragment"

好的。我被困住了并且头痛......我不知道如何访问其他布局的 View ，因为膨胀不起作用。这是我的代码。

WriteRouteActivity.java

public class WriteRouteActivity extends AppCompatActivity {

    private Toolbar tb;
    private TextView txt_toolbar_title;
    private Button btnSearchPlaces;
    private LinearLayout parentLayout, placesCoverLayout;
    private View popupView;
    private ImageView imgShowPlaces;
    private boolean isKeyBoardVisible;
    private int keyboardHeight;
    private EditText edtSearchPlaces;
    private PopupWindow popupWindow;

    //popupView
    private TabLayout tabLayout;
    private FrameLayout frameLayout;

    //prework
    private int minusVal;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_write_route);
        initView();

    }

    private void initView() {
        //for activity and native back button

        tb = (Toolbar) findViewById(R.id.nav_toolbar);
        setSupportActionBar(tb);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

有人可以帮忙吗？

最佳答案

发生此错误的原因是 fragment 管理器找不到必须在其上膨胀 fragment 的 View 。

fragment 事务链接到 Activity ，因此会发生此错误，因为框架布局不是该主 Activity xml 的一部分。因此它无法找到添加 fragment 的位置。必须在 Activity 内添加 fragment 。

您要做的就是在主要 Activity 中提供 View 的 ID。例如您的主视图

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_parent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/mainView"//like this
android:orientation="vertical">

<include layout="@layout/nav_toolbar" />

<fragment
    android:id="@+id/google_map"
    class="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />


<include
    android:id="@+id/footer_layout"
    layout="@layout/footer_edittext"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

<LinearLayout
    android:id="@+id/footer_for_places"
    android:layout_width="match_parent"
    android:layout_height="@dimen/keyboard_height"
    android:background="@android:color/transparent"
    android:orientation="vertical"
    android:visibility="gone" />
 </LinearLayout>

您尝试膨胀 fragment 的 View 必须位于 Activity 内部。现在当你尝试时

frManager.beginTransaction().add(R.id.mainView, ((Fragment) Fragment_zasin.class.newInstance()), tag).commit();

fragment 将加载到您的 Activity 的此 View 上。
