包含链接的EditText在三星设备上崩溃

android
10

这段代码在其他设备上运行得非常好，但在三星设备上崩溃。我似乎无法真正弄清楚为什么，但我知道如果我使用TextView它就不会崩溃。问题是，我需要一个EditText来输入内容，而且它可以包含多个链接。我已经花了过去一天的时间寻找解决方案，但没有成功，所以我想在这里发布：

注意：我测试的Nexus和Motorola设备似乎可以正常工作：
是否有某些解决方法我错过了？我猜测三星修改了如何处理EditText框中的链接？

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
      EditText t3 = (EditText) findViewById(R.id.text3);
      t3.setText(
              Html.fromHtml(
                      "<b>text3:</b>  Text with a " +
                              "<a href=\"http://www.google.com\">link</a> " +
                              "created in the Java source code using HTML."));
      t3.setMovementMethod(LinkMovementMethod.getInstance());

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

如果有帮助的话，这是堆栈跟踪：

logcat 一下，可以吗？你在模拟器中试过了吗？如果它在某些设备上工作而在其他设备上不工作，那么很可能是三星对某些东西进行了微调。 - ucsunil
它也可以在模拟器上运行，是的。虽然我需要一个解决方法才能让它在三星设备上运行。 - nitrobuster
从您的logcat来看，似乎确实是三星特定的问题，因为其中没有任何指向代码问题的内容。您必须使用什么解决方法才能在三星设备上运行它？我正在尝试在谷歌上搜索，我看到三星的开发者网站有一个页面，显示包含HTML文本但不包含链接的EditText。 - ucsunil
我还没有完全想出一个解决方法，我仍在努力寻找解决方案。 - nitrobuster
有趣的是 - 当我错误地使用TextView样式作为EditText而不是实际的EditText时，我在三星设备上收到了相同的堆栈跟踪。 - Boris Treukhov

这篇文章对我很有帮助，如果有人对答案感兴趣的话。该文章涉及点击链接和在Android中的EditView中复制/粘贴菜单相关的内容。请参考这里。

使用您链接中提供的自定义MovementMethod，是否可以避免出现NullPointerException？ - Csaba Szugyiczki

是的，它确实帮助我避免了它们。 - nitrobuster
