//==============================

mCheckBoxView = (CheckBox) findViewById(R.id.settings_synch_delet);

mEditTextView = (EditText) findViewById(R.id.account_password);




mCheckBoxView.setOnCheckedChangeListener(checkBox_Listener);




private CheckBox.OnCheckedChangeListener checkBox_Listener = new CheckBox.OnCheckedChangeListener() {

       @Override

        public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {

           if(mCheckBoxView.isChecked()){

              //文本正常显示

             mEditTextView.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);

              Editable etable = mEditTextView.getText();

              Selection.setSelection(etable, etable.length());

           }else{

              //文本以密码形式显示

              mEditTextView.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);

              //下面两行代码实现: 输入框光标一直在输入文本后面

              Editable etable = mEditTextView.getText();

              Selection.setSelection(etable, etable.length());

           }

        } 

    };
