结尾带有固定字符的可编辑文本

添加文本更改侦听器并在中修改文本 afterTextChanged 方法,如下所示,首先移除 %

editText.addTextChangedListener(new TextWatcher() {

   @Override
   public void afterTextChanged(Editable s) {
       editText.setText(s.getText().toString().replaceAll("%", "")+"%");
       editText.setSelection(editText.getText().length()-1) // just reset the cursor position before %
   }

   @Override    
   public void beforeTextChanged(CharSequence s, int start,
     int count, int after) {
   }

   @Override    
   public void onTextChanged(CharSequence s, int start,
     int before, int count) {

   }
  });
