Question

我正在使用JSON解析一堆数据并将其放入textview中，我希望能够检测链接并在单击时转到这些链接。我已经能够使用以下代码检测链接：

<TextView
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:layout_height="wrap_content"
    android:text="TextView"
    android:layout_width="wrap_content"
    android:id="@+id/txtTitle"
    android:textColor="#000000"
    android:layout_toRightOf="@+id/imgThumbnail"
    android:layout_marginTop="6dip"
    android:layout_marginLeft="6dip"
    android:autoLink="all"
    android:linksClickable="true">
</TextView>

点击突出显示的链接后，它会崩溃应用程序，但会出现此错误：

提前致谢。

Answer 1

在我看来，您所看到的错误可能与错误的上下文有关。如果要设置TextView的文字，请确保初始化context的{{1}}是正确的。例如：

TextView

再次确保传递此上下文属于活动。只是编写TextView tv = new TextView(YourActivityName.this);可能会导致问题，具体取决于您定义TextView的位置。您是否在this等内使用this，那么该上下文应该没问题。如果您在任何runnable或OnCreate等内部定义TextView，那么这可能会导致您面临的问题。

希望这可以帮助您识别。有关更准确的答案，请发布您定义TextView的相关Java代码。

Answer 2

你有一件事要在你的代码中删除＆＃34; +＆＃34;在id附近你的形象拇指指甲

<TextView
android:textAppearance="?android:attr/textAppearanceLarge"
android:layout_height="wrap_content"
android:text="TextView"
android:layout_width="wrap_content"
android:id="@+id/txtTitle"
android:textColor="#000000"
android:layout_toRightOf="@id/imgThumbnail"
android:layout_marginTop="6dip"
android:layout_marginLeft="6dip"
android:autoLink="all"
android:linksClickable="true">

你说它是链接，但你没有任何网址，你很难对文本视图进行编码在android：text

TextView中的链接没有响应
