输入密码的显隐藏

效果图：

① 最简单的显隐藏：

先在xml中设定edit 输入类型android:inputType="textPassword"

if(isChecked){

//如果选中，显示密码

editText.setTransformationMethod(HideReturnsTransformationMethod.getInstance());

}else{

//否则隐藏密码

editText.setTransformationMethod(PasswordTransformationMethod.getInstance());

}

②显示之后3s隐藏

//显隐藏操作

showOrHintPws.setOnClickListener(new View.OnClickListener() {    @Override    public void onClick(View v) {        mHandler.removeMessages(1);        if (showPwdText) {            password_edit_text.setTransformationMethod(PasswordTransformationMethod.getInstance());            password_edit_text.setSelection(password_edit_text.getText().toString().length());            showOrHintPws.setBackgroundResource(R.mipmap.login_icon_eyeclose);        } else {            showOrHintPws.setBackgroundResource(R.mipmap.login_icon_eye);            password_edit_text.setTransformationMethod(HideReturnsTransformationMethod.getInstance());            password_edit_text.setSelection(password_edit_text.getText().toString().length());//设置光标移动到最后一位            Message msg = new Message();            msg.what = 1;            mHandler.sendMessageDelayed(msg, 3000);        }        showPwdText = !showPwdText;    }});

 private Handler mHandler = new Handler() {        @Override        public void handleMessage(Message msg) {            super.handleMessage(msg);            switch (msg.what) {                case 1:                    password_edit_text.

                    setTransformationMethod(PasswordTransformationMethod.getInstance());                    password_edit_text.setSelection(password_edit_text.getText().toString().length());                    showOrHintPws.setBackgroundResource(R.mipmap.login_icon_eyeclose);                    showPwdText = false;                    mHandler.removeMessages(0);                    break;                                default:                    break;            }        }    };
