Answer 1

public void onCheckBox(View v2) 
{ 
CheckBox cb = (CheckBox)this.findViewById(R.id.pass_Check); 
EditText et1=(EditText)this.findViewById(R.id.edt_Pass); 
    if(cb.isChecked()) 
    { 
    et1.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD); 
    } 
    else 
    { 
    et1.setInputType(129); 
    } 

} 

或

public void onCheckBox(View v2) 
{ 
    CheckBox cb = (CheckBox)this.findViewById(R.id.checkBox); 
    cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(CompoundButton compoundButton, boolean  b) { 
      if(!b) 
      { 
        password.setTransformationMethod(PasswordTransformationMethod.getInstance()); 
      } 
      else 
      { 
       password.setTransformationMethod(HideReturnsTransformationMethod.getInstance()); 
      } 
     } 
    }); 

}
