Selecting text on TextView (android 2.2)

How to implement 开发者_如何学运维selecting text capability on Android 2.2? I searched Google but can't find a solution.

This is the only way I've found (from google) to support it for android 1.6+, it works but it's not ideal, I think in stock android you can't hold down a webview to highlight until v2.3, but I may be mistaken..

By the way this is for a webview, it might also work on textview, but I haven't tried it

(Note: this is currently what my shipped app is using, so it works with all the phones I've had it tested on, but the only reason I found this question was because I was searching and hoping that someone had come up with a better way by now)

I've just got a menu item called "Select text" which calls the function "selectnCopy()"

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    //..
    switch (item.getItemId()) {
        case R.id.menu_select:
            selectnCopy();
            return true;
    //..
    }
}

Which looks like this:

public void selectnCopy() {
    Toast.makeText(WebClass.this,getString(R.string.select_help),Toast.LENGTH_SHORT).show();
    try {
        KeyEvent shiftPressEvent = new KeyEvent(0, 0, KeyEvent.ACTION_DOWN,
                KeyEvent.KEYCODE_SHIFT_LEFT, 0, 0);
        shiftPressEvent.dispatch(wv);
    } catch (Exception e) {
        throw new AssertionError(e);
    }
}

Notice I've put the select_help string there as a toast, that's just because it's not immediately clear to the user how it's supposed to work

<string name="select_help">Touch and drag to copy text.</string>

The Link @Stefan Hållén provided only worked after API Level 11.

And Android 2.2 is API Lv.8, that's the reason why you cannot get a resource identifier.

Have you set the text to be selectable? like this:

android:textIsSelectable="false"  //OR true

See the Documentation for further reference.

After a long and time consuming search, I can't find a component that can select text in textview for android API level <=11. I have written this component that may be of help to you : new Selectable TextView in android 3 (API <=11) component

An interesting workaround:

You could try displaying your text in a webview.

You just have to write the HTML tags and all of that into your string to display, and it should be selectable using the WebKit browser.

This should be fairly lightweight and transparent to the user, and I think it would solve your problem.

Let me know if you need a code example, it should be fairly simple. Just check out the WebView docs on http://developer.android.com/resources/tutorials/views/hello-webview.html

Best of luck!
