如何动态设置EditText输入的文字为密码形式

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())

}

}

}

　int newHeight = 200

//注意这里，到底是用ViewGroup还是用LinearLayout或者是FrameLayout，主要是看你这个EditTex

//控件所在的父控件是啥布局，如果是LinearLayout，那么这里就要改成LinearLayout.LayoutParams

ViewGroup.LayoutParams lp = editText.getLayoutParams()

lp.height = newHeight

editText.setLayoutParams(lp)
