不知道是不是android6.0的bug, 在我环境上100%可以重现:
先说环境:
API 23
手机Nexus5
android版本6.0
先设置TextView 的textIsSelectable="true", 然后setMovementMethod
此时长按文本, 等到选择文本的ActionMode弹出来, 然后单击两个指针中间选中的高亮文本, 报如下错误:
Invalid offset: -1. Valid range is [0, xx(数字)]

异常并没有上报到自己写的代码, baidu和蹩脚的bing搜了一把貌似没人遇到这个问题.
顺便吐个槽现在墙的越来越厉害了, SO用了google站上的jQuery只能看不能登录了...
简单的测试代码:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity">
<TextView
android:id="@+id/txtview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textIsSelectable="true" />
</RelativeLayout>
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView textView = (TextView) findViewById(R.id.textview);
SpannableString ss = new SpannableString("哈哈哈哈哈哈哈哈");
ss.setSpan(new ClickableSpan() {
@Override
public void onClick(View widget) {
Toast.makeText(MainActivity.this, "onclick", Toast.LENGTH_SHORT).show();
}
}, 0, 3, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.setText(ss);
textView.setMovementMethod(LinkMovementMethod.getInstance());
}
}
bing出来貌似有人给 Google 官方 提出了这个问题, 遗憾的是墙的太厉害,点不开啊啊...
我在recycleView中使用这个功能的时候 报错数组越界
