我正在尝试用不同的容器替换容器中的片段。我在显示的新片段中制作了Toast,但布局没有显示。
这是我替换片段的地方:
Bundle bundle = new Bundle();
bundle.putString("title", textContentList.get(position).getTitle());
bundle.putString("crated", textContentList.get(position).getCreated());
bundle.putString("author", textContentList.get(position).getAuthor());
bundle.putString("fullContent", textContentList.get(position).getFullContent());
MessageDetailsFragment messageDetailsFragment = new MessageDetailsFragment();
messageDetailsFragment.setArguments(bundle);
replaceFragment(messageDetailsFragment);
public void replaceFragment(Fragment fragment){
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.container, fragment);
transaction.commit();
}
这是我的片段布局:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text_container"
android:orientation="vertical"
android:layout_marginTop="70dp"
android:background="?android:colorBackground"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
style="@style/headings"
android:text="Author"
android:layout_marginTop="10dp"
android:id="@+id/message_details_author"/>
<TextView
style="@style/subTxt_messageDetails"
android:text="Receiver"
android:id="@+id/message_details_receiver"/>
<View
android:layout_width="320dp"
android:layout_gravity="center"
android:layout_height="1dp"
style="@style/dividerLine" />
<TextView
style="@style/headings"
android:layout_marginTop="10dp"
android:text="Title"
android:id="@+id/message_details_title"/>
<TextView
style="@style/subTxt_messageDetails"
android:text="Date"
android:id="@+id/message_details_date"/>
<View
android:layout_width="320dp"
android:layout_gravity="center"
android:layout_height="1dp"
style="@style/dividerLine" />
<TextView
android:text="Full content"
style="@style/subTxt_messageDetails"
android:layout_marginTop="15dp"
android:id="@+id/message_details_full_content"/>
<TextView
style="@style/subTxt_messageDetails"
android:text="Sent by SMS"
android:textSize="15sp"
android:layout_marginTop="15dp"
android:id="@+id/message_sent_by"/>
</LinearLayout>
这是我的新片段:
public class MessageDetailsFragment extends Fragment {
private String title, created, author, fullContent;
private TextView textViewTitle, textViewDate, textViewAuthor, textViewFullContent;
private Bundle bundle;
private Context context;
public MessageDetailsFragment(){
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
bundle = this.getArguments();
title = bundle.getString("title");
created = bundle.getString("created");
author = bundle.getString("author");
fullContent = bundle.getString("fullContent");
context = getActivity();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_message_details, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState){
Toast.makeText(context, "ADDASD", Toast.LENGTH_SHORT).show();
textViewTitle = (TextView) getView().findViewById(R.id.message_details_title);
textViewTitle.setText(title);
textViewDate = (TextView) getView().findViewById(R.id.message_details_date);
textViewDate.setText(created);
textViewAuthor = (TextView) getView().findViewById(R.id.message_details_author);
textViewAuthor.setText(author);
textViewFullContent = (TextView) getView().findViewById(R.id.message_details_full_content);
textViewFullContent.setText(fullContent);
}
}

你的样品不具有可重复性,因为它指的是没有给出的样式等,因此一般来说很难确定......
要调试Fragment布局,首先要清除除父ViewGroup之外的所有内容。给它一个易于识别的颜色,这样你就可以看到它在你的应用程序中实际出现时就已经出现了。
如果出现,则问题是您的布局。如果没有,那很可能是你的代码。
完成此操作后,您可以逐步添加其他视图。
例如
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="@color/Red"
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout

感谢所有答案。事实证明我试图将片段插入到我也在应用程序中使用的viewpager中。通过创建一个新的FrameLayout并将其插入其中我解决了我的问题。
