android - 超链接获取 AndroidRuntimeException

Question

我在这个应用程序中使用 ViewPager 和 SherlockFragments 并尝试在 TextView 中设置超链接。当我点击超链接时，应用程序崩溃了。此方法之前在其他应用程序中有效，但现在我遇到了 AndroidRuntimeException。

public class FragmentNewsPage extends SherlockFragment {
/*
* 
**/
public void newsShow(String news) {

    mShareIntent.putExtra(Intent.EXTRA_TEXT, news);

    swipeRefreshLayout.setRefreshing(false);

    mMainText.setMovementMethod(LinkMovementMethod.getInstance());
    mMainText.setText(Html.fromHtml(mLink));
    mMainText.append("\n\n" + news);

    }
}

布局

    <?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/blue"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin">

<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/swipe_refresh_page"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:id="@+id/scrollView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentEnd="true"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:scrollbarThumbVertical="@drawable/scrollbar_vertical_thumb">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/newsText"
            android:textSize="20sp"
            android:textStyle="bold"
            android:clickable="true"
            android:textColor="@android:color/white"
            android:layout_gravity="center_horizontal"/>
    </ScrollView>

</android.support.v4.widget.SwipeRefreshLayout>

<LinearLayout
    android:id="@+id/linearLayout_newsPage"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentTop="false"
    android:layout_centerHorizontal="true"
    android:orientation="horizontal"/>

</RelativeLayout>

Answer 1

尝试从 Activity 上下文中调用新 Activity ，例如:

getActivity().startActivity(...);
