android EditView 文本密码显示与…

实现功能：密码显示与隐藏，文本输入框光标始终位于文本后面.

//==============================
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);
             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
             mEditTextView.getText();
             Selection.setSelection(etable, etable.length());
         
       }
