好吧,我问了一个问题并得到了90%的答案,我需要解决其余的10%。

它基本上是一个事件页面,所以在从StackView点击所选项目时,它会打开另一个片段,里面有2个textViews和1个imageView, 所有这些页面(10+)都是对称的,所以我决定让它变得动态,这样它就很容易处理和处理。

EventsFragment

public class DynamicEventsPage extends Fragment{
    public static final String BUNDLE_STRING_KEY = "BUNDLE_STRING_KEY";
    public static final String BUNDLE_DRAWABLE_KEY = "BUNDLE_DRAWABLE_KEY";
    public static final String BUNDLE_STRING_DESC_KEY = "BUNDLE_STRING_DESC_KEY";

    public static Fragment newInstance(final int stringId,final int descStringId, final int drawableId) {
        Bundle bundle = new Bundle();
        bundle.putInt(BUNDLE_STRING_KEY, stringId);
        bundle.putInt(BUNDLE_DRAWABLE_KEY, drawableId);
        bundle.putInt(BUNDLE_STRING_DESC_KEY,descStringId);
        Fragment fragment = new DynamicEventsPage();
        fragment.setArguments(bundle);
        return fragment;
    }

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

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        Bundle bundle = getArguments();
        ((ImageView)view.findViewById(R.id.imageView)).setImageResource(bundle.getInt(BUNDLE_DRAWABLE_KEY));
        ((TextView)view.findViewById(R.id.textView)).setText(bundle.getInt(BUNDLE_STRING_KEY));
        ((TextView)view.findViewById(R.id.textViewdesc)).setText(bundle.getInt(BUNDLE_STRING_DESC_KEY));
    }

}

DynamicEventPage

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:weightSum="1">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="Medium Text"
        android:id="@+id/textView"
        android:layout_weight="0.40" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="New Text"
        android:id="@+id/textViewdesc"
        android:layout_weight="0.40" />

    <ImageView
        android:layout_width="228dp"
        android:layout_height="wrap_content"
        android:id="@+id/imageView"
        android:layout_weight="0.40" />

</LinearLayout>

dynamic_events_page.xml

E/AndroidRuntime: android.content.res.Resources$NotFoundException: String resource ID #0x7f0b0001

E/AndroidRuntime:     at package.DynamicEventsPage.onViewCreated(DynamicEventsPage.java:39)

错误是获取

{{1}}

那么修复是什么?

将newInstance更改为String而不是int

public static Fragment newInstance(final String eventName,final String eventDescr, final int drawableId) {
        Bundle bundle = new Bundle();
        bundle.putString(BUNDLE_STRING_KEY, stringId);
        bundle.putInt(BUNDLE_DRAWABLE_KEY, drawableId);
        bundle.putString(BUNDLE_STRING_DESC_KEY,descStringId);
        Fragment fragment = new DynamicEventsPage();
        fragment.setArguments(bundle);
        return fragment;
}

和onViewCreate读取String而不是int

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    Bundle bundle = getArguments();
    ((ImageView)view.findViewById(R.id.imageView)).setImageResource(bundle.getInt(BUNDLE_DRAWABLE_KEY));
    ((TextView)view.findViewById(R.id.textView)).setText(bundle.getString(BUNDLE_STRING_KEY));
    ((TextView)view.findViewById(R.id.textViewdesc)).setText(bundle.getString(BUNDLE_STRING_DESC_KEY));
}
onItemClick中的

更改

Fragment eventDescFragment = new DynamicEventsPage().newInstance(R.array.event_stack,R.array.event_desc_stack,eventLogo.getResourceId(position, -1));

String name = (position < eventName.length) ? eventName[position] : "";
String description = (position < eventDesc.length) ? eventDesc[position] : "";
Fragment eventDescFragment = DynamicEventsPage.newInstance(eventName, description,eventLogo.getResourceId(position, -1));

显示错误消息

  

Resources $ NotFoundException:字符串资源ID#0x7f0b0001

这意味着您正在尝试引用strings.xml文件中没有的字符串变量。

希望这会有所帮助。

答案 2 :(得分:0)

您正在将图像视图的文本分配给字符串数组R.array.somearray,这是错误的。您应该将其分配给字符串资源R.string.somestring

Fragment初始化中的其他一些错误。它应该是

Fragment eventDescFragment = DynamicEventsPage.newInstance(R.string.event_stack,R.string.event_desc_stack,eventLogo.getResourceId(position, -1));

你拥有它的方法就是初始化一个新的Fragment并保留它然后在静态newInstance方法上初始化一个新的。
