如何确定何时选择文本[Android [EditText]] [英] How to determine when text is selected [Android [EditText]]

问题描述

是否可以确定何时选择文本，何时不选择文本?

Is possible to determine when text is selected and when is not?

我正在使用Google搜索，并使用find onSelectionChanged()方法或setOnLongClickListener()来确定用户longClick何时编辑文本，以便他进行选择，但是在两种情况下，它都无法帮助我确定何时不使用该用户.选择任何文本(我可以将按钮设置为不可见)...

I was googling and I find onSelectionChanged() method or setOnLongClickListener() for determining when user longClicks the editText so when he made selection, but in both cases it can't help me with determining, when the user is not selecting any text (I could set button invisible)...

推荐答案

您可以使用

yourEditText.setOnTouchListener(new View.OnTouchListener() {
          @Override
          public boolean onTouch(View v, MotionEvent event) {

            if (MotionEvent.ACTION_UP == event.getAction()) {

              if (yourEditText.hasSelection()) {
                // if true, the text in the EditText is selected
              }

            return false;
          }
        });

那应该做.

That should do it.
