在TextView中选择文本（安卓2.2） [英] Selecting text on TextView (android 2.2)

问题描述

如何实现在Android 2.2中选择文本的能力？我搜索谷歌，但不能找到一个解决方案。

How to implement selecting text capability on Android 2.2? I searched Google but can't find a solution.

推荐答案

这是我发现（从谷歌）的唯一途径，以支持它为Android 1.6+，它的工作原理，但它并不理想，我认为股票的android你不能按住一个web视图突出到V2.3，但我可能是错了。

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..

到这是一个web视图的方式，它也可能在工作TextView的，但我还没有尝试过

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

（注：这是目前我什么运的应用程序是使用，所以它适用于所有我已经受够了测试，在手机上，但我发现这个问题的唯一原因是因为我正在寻找，并希望有人来了与现在更好的方法）

(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)

我刚刚拿到了所谓的选择文本，它调用函数selectnCopy（）菜单项

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;
    //..
    }
}

看起来像这样：

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);
    }
}

的通知我已经把select_help串那里举杯，这只是因为它不是立即清楚用户如何它应该工作

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>
