How to allow the user to select a text range in a

问题:

I've got a TextView that I would like to allow the user to select a range of text from within it. The TextView takes up the entire width and height of the device (minus some padding and a title at the top). In an EditText if you long-click you get a selection overlay that allows you to set your selection left and right bounds. I'd like this functionality in a TextView. I've read that in API level 9 (2.3) (http://developer.android.com/sdk/android-2.3.html) there are new text selection controls, but I'm having difficulty implementing this. I'm doing this right now:

eic = new InputConnection( bookTextView );
eic.beginBatchEdit();

But it doesn't do anything noticable. Does anyone know how to use InputConnection correctly? Thanks.

Edit: I don't necessarily need to use what I was attempting above. I ultimately want to use either a TextView or an EditText which looks and feels like a TextView and be able to select text using a dragging cursor. Then I would like to manipulate the selected text with various context menu options (or a menu that pops up above the selected text).

Here is an idea.. Add an EditText with a TextView background, Here is an example

<EditText 
android:text=" This is not an editable EditText" 
android:id="@+id/EditText01" 
android:layout_width="wrap_content" 
android:textColor = "@android:color/white"
android:editable = "false"
android:cursorVisible="false"
android:layout_height="wrap_content"
android:background = "@android:drawable/dark_header">
</EditText>

add this to your xml in the place of TextView

You can enable the TextView's Spannable storage. See Highlight Text in TextView or WebView for an example.

You could display the text in a WebView and enable text selection. If you want to only use a textview/edittext, here is an answer that might help you and here is information on the Spannable class that might help you accomplish what you want.

Actually, you do not have to develop this feature by yourself. You just need to use EditText instead TextView, while you set the android:editable of EditText to false. My idea is the same as sandy's.
