禁用与单选按钮检查EditText

问题描述：

此代码无法正常工作，错在哪里？我不希望允许用户输入直到radiobutton2检查禁用与单选按钮检查EditText

EditText t4 = (EditText)findViewById(R.id.editText3); 

RadioButton rb = (RadioButton) findViewById(R.id.radioButton1); 
RadioButton rb2 = (RadioButton) findViewById(R.id.radioButton2); 
RadioGroup rg =(RadioGroup) findViewById(R.id.G1); 


    rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(RadioGroup group, int checkedId) { 

      if(checkedId==R.id.radioButton1) 
      { 
       t4.setEnabled(false); 
      } 

      if(checkedId==R.id.radioButton2) 
      { 
       t4.setEnabled(true); 
      } 


     } 
    });

在Android中禁用edittext有点麻烦。尝试添加't4.setFocusable（false）;'结合't4.setEnabled（false）;' –

答

t4.setEnable(rb2.isChecked()); 

rb2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
      @Override 
      public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
       t4.setEnable(isChecked); 
      } 
     });

你可以试试下面给出的代码？

EditText t4 = (EditText)findViewById(R.id.editText3); 

RadioButton rb = (RadioButton) findViewById(R.id.radioButton1); 
RadioButton rb2 = (RadioButton) findViewById(R.id.radioButton2); 
RadioGroup rg =(RadioGroup) findViewById(R.id.G1); 


rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
    @Override 
    public void onCheckedChanged(RadioGroup group, int checkedId) { 

     if(checkedId==R.id.radioButton1) 
     { 
      changeEditTextAvailability(t4, false); 
     } 

     if(checkedId==R.id.radioButton2) 
     { 
      changeEditTextAvailability(t4, true); 
     } 


    } 
}); 

private void changeEditTextAvailability(EditText editText, boolean status) { 
    editText.setFocusable(status); 
    editText.setEnabled(status); 
    editText.setCursorVisible(status); 
    editText.setFocusableInTouchMode(status) 
}

你可以试试这个

检查“单选框”被选中：isChecked()

禁用的EditText android系统：setFocusable()

EditText t4 = (EditText)findViewById(R.id.editText3); 

RadioButton rb = (RadioButton) findViewById(R.id.radioButton1); 
RadioButton rb2 = (RadioButton) findViewById(R.id.radioButton2); 
RadioGroup rg =(RadioGroup) findViewById(R.id.G1); 

if (rb.isChecked()) { 
    t4.setFocusable(true); 
} else { 
    t4.setFocusable(false); 
} 

if (rb2.isChecked()) { 
    t4.setFocusable(false); 
} else { 
    t4.setFocusable(true); 
}

这项工作只有第一次检查。意思是如果一旦我尝试了两个然后t4禁用永远。再次我需要回去。你能告诉我如何编码，以便它可以工作很多次，因为我更改了单选按钮的选择？ –

@MuhammadAkram问题是为什么你需要同时检查两个按钮？ –

@MuhammadAkram好吧，我改变你可以尝试 –

if (cbProhibitEditPW.isChecked()) { // disable editing password 
     editTextPassword.setFocusable(false); 
     editTextPassword.setFocusableInTouchMode(false); // user touches widget on phone with touch screen 
     editTextPassword.setClickable(false); // user navigates with wheel and selects widget 
} else { // enable editing of password 
     editTextPassword.setFocusable(true); 
     editTextPassword.setFocusableInTouchMode(true); 
     editTextPassword.setClickable(true); 
}

试试这个代码

的问题是，你还没有初始化，初始化的意见后，验证试试这个在onCreate()

EditText t4 = (EditText)findViewById(R.id.editText3); 

RadioButton rb = (RadioButton) findViewById(R.id.radioButton1); 
RadioButton rb2 = (RadioButton) findViewById(R.id.radioButton2); 
RadioGroup rg =(RadioGroup) findViewById(R.id.G1); 

if (rb.isChecked()) { 
    t4.setFocusable(true); 
} 

if (rb2.isChecked()) { 
    t4.setFocusable(false); 
} 
rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(RadioGroup group, int checkedId) { 

      if(checkedId==R.id.radioButton1) 
      { 
       t4.setEnabled(false); 
      } 

      if(checkedId==R.id.radioButton2) 
      { 
       t4.setEnabled(true); 
      } 


     } 
    });

这将限制用户输入时屏幕发射

解决方法是致电除EditText上的setEnabled(false)之外，还有。更改您的代码，如下所示：

EditText t4 = (EditText)findViewById(R.id.editText3); 

RadioButton rb = (RadioButton) findViewById(R.id.radioButton1); 
RadioButton rb2 = (RadioButton) findViewById(R.id.radioButton2); 
RadioGroup rg =(RadioGroup) findViewById(R.id.G1); 


    rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(RadioGroup group, int checkedId) { 

      if(checkedId==R.id.radioButton1) 
      { 
       t4.setEnabled(false); 
       t4.setFocusable(false); 
      } 

      if(checkedId==R.id.radioButton2) 
      { 
       t4.setEnabled(true); 
       t4.setFocusable(true); 

      } 


     } 
    });
