即使在添加字符后仍然会出现Edittext的常量后缀

Question

我想要类似这样的内容。

即使输入数字后，“X10^3C'should保持不变。

Answer 1

使用文本守望实现这一

//global variable 
     Boolean isAvaialable = false; 

    // text watcher 
     txtAdvertise.addTextChangedListener(new TextWatcher() { 
        @Override 
        public void beforeTextChanged(CharSequence s, int start, int count, int after) { 

        } 

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

        } 

        @Override 
        public void afterTextChanged(Editable s) { 


          if(!txtAdvertise.getText().toString().contains("X10^3c") && !isAvaialable) { 
           txtAdvertise.setText(txtAdvertise.getText() + "X10^3c"); 
           isAvaialable = true; 
          } 
         else if(txtAdvertise.getText().length() == 0 && isAvaialable && !txtAdvertise.getText().toString().contains("X10^3c")){ 
           txtAdvertise.setText(txtAdvertise.getText() + "X10^3c"); 
           isAvaialable = false; 
         } 
    } 
     });
