android中EditView中的可点击链接和复制/粘贴菜单

问题描述

我的 Android 应用中有一个 EditText 视图.我需要其中的内部链接"，这意味着我需要在 EditText 中使用一些按钮或跨度，并且使用 onClick 到此按钮我可以执行一些操作(而不是重定向到 Web页).我用这样的 ClickableSpan() 实现了这个按钮

I have an EditText view in my Android app. I need "inner links" in it, this means that I need some buttons or span inside EditText and with onClick to this button I can do some actions (not redirect to web page).I realized this buttons with ClickableSpan() like this

linkWord = "my link";
link = new SpannableString(linkWord);
cs = new ClickableSpan(){
private String w = linkWord;
    @Override
    public void onClick(View widget) {
    wrd.setText(w);
    }
};
link.setSpan(cs, 0, linkWord.length(), 0);
et.append(link);

为了使这个跨度可点击，我使用了

For make this span clickable I used

et.setMovementMethod(LinkMovementMethod.getInstance());

内部链接"工作正常，但在使用 et.setMovementMethod() 后，在 OnLongClick 菜单上禁用复制和粘贴项目.这是一个问题，因为我需要 EditText 中的链接"并同时从该视图中复制文本.

"Inner links" works fine, but after using et.setMovementMethod() copy and paste items are disable on OnLongClick menu. And this is a problem, because I need "links" in EditText and copy text from this view in the same time.

我有想法在侦听器 OnLongClickListener 中设置类似 removeMovementMethod() 的东西，用于临时禁用链接"功能并使用带有复制/粘贴的菜单，并在处理文本后打开再次 setMovementMethod() 方法.但我不知道如何实现这一点.

I have idea to set in listener OnLongClickListener something like removeMovementMethod() for temporary disable "links" function and use menu with copy/paste and after coping text switch on setMovementMethod() method again. But I don't know how to realize this.

对于我使用的 EditText 中的可点击链接

For clickable links inside EditText I used

et.setMovementMethod(LinkMovementMethod.getInstance());

在这种情况下，在 longClick 菜单中没有复制/粘贴项目.为了激活它们，我需要回到正常的 EditText 状态，我可以这样做:

in this case in longClick menu there are not copy/paste items.For activate them I need back to normal EditText state, I can do it with:

et.setMovementMethod(ArrowKeyMovementMethod.getInstance());

此方法后链接将不起作用但出现正常的长按菜单.

After this method links will not work but appear normal longClick menu.

因此我在上下文菜单中添加了新项目并在这两个选项之间切换:

Therefore I added new item to the context menu and switched between this two options:

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    if(et.getSelectionStart() == -1){ // in case of setMovementMethod(LinkMovementMethod.getInstance())
        menu.add(0, 1, 0, "Enable copy");
    }
    else{
        menu.add(0, 2, 0, "Enable links");
    }
}
@Override
public boolean onContextItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case 1:
          et.setMovementMethod(ArrowKeyMovementMethod.getInstance());
          et.setSelection(0, 0);
              //re-register EditText for context menu:
          unregisterForContextMenu(et);
          registerForContextMenu(et);
          break;
      case 2:
          et.setMovementMethod(LinkMovementMethod.getInstance());
          break;
      }
      return true;
  }

我还为上下文菜单注册了 EditText:

Also I registered EditText for context menu:

registerForContextMenu(et);
