仿支付宝/微信的password输入框效果GridPasswordView解析，把一些设置和一些关键的地方列了出来，方便大家使用，可能能够省一部分的时间，也算是自己的积累吧。

1.password框能够输入的类型PasswordType

public enum PasswordType {NUMBER, TEXT, TEXTVISIBLE, TEXTWEB;
}

这里能够自行加入类型，然后在GridPasswordView中改动

    @Overridepublic void setPasswordType(PasswordType passwordType) {boolean visible = getPassWordVisibility();int inputType = InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD;switch (passwordType) {case TEXT:inputType = InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD;break;case TEXTVISIBLE:inputType = InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD;break;case TEXTWEB:inputType = InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_WEB_PASSWORD;break;}for (TextView textView : viewArr)textView.setInputType(inputType);setPasswordVisibility(visible);}

2.PasswordView中的抽象方法的作用

interface PasswordView {//获取passwordString getPassWord();//清空passwordvoid clearPassword();//设置passwordvoid setPassword(String password);//设置password可见性void setPasswordVisibility(boolean visible);//password可见性的切换void togglePasswordVisibility();//设置password改变监听void setOnPasswordChangedListener(GridPasswordView.OnPasswordChangedListener listener);//设置password类型void setPasswordType(PasswordType passwordType);
}

3.GridPasswordView中还有些方法没有去操作。有须要能够自己去写

setBackground(Drawable)
setBackgroundColor(int)
setBackgroundResource(int)
setBackgroundDrawable(Drawable)

这个类是View的主类。能够通过这个类去满足你的需求

4.在GridPasswordView中设置框框颜色和背景颜色(绿色和红色)

private static final int DEFAULT_LINECOLOR = 0xaa61cea8;
private static final int DEFAULT_GRIDCOLOR = 0xffe66961;

5.设置文本的大小和颜色(40px和蓝色)

private static final int DEFAULT_TEXTSIZE = 40;
textColor = ColorStateList.valueOf(getResources().getColor(android.R.color.holo_blue_light));

6.在gridpasswordview_styles.xml中设置了样式，大家依据须要更改

    <style name="GridPasswordView.TextView"><item name="android:layout_width">0dp</item><item name="android:layout_height">match_parent</item><item name="android:background">@null</item><item name="android:gravity">center</item><item name="android:layout_weight">1</item><item name="android:singleLine">true</item></style><style name="GridPasswordView.EditText" parent="GridPasswordView.TextView"><item name="android:cursorVisible">false</item></style><style name="GridPasswordView.Divider"><item name="android:layout_width">1dp</item><item name="android:layout_height">match_parent</item><item name="android:layout_marginTop">1dp</item><item name="android:layout_marginBottom">1dp</item></style>

7.在gridpasswordview_attr.xml设置属性值

    <declare-styleable name="gridPasswordView"><attr name="textColor" format="color|reference" /><attr name="textSize" format="dimension" /><attr name="lineColor" format="color" /><attr name="gridColor" format="color" /><attr name="lineWidth" format="dimension" /><attr name="passwordLength" format="integer" /><attr name="passwordTransformation" format="string" /><attr name="passwordType" format="enum"><enum name="numberPassword" value="0" /><enum name="textPassword" value="1" /><enum name="textVisiblePassword" value="2" /><enum name="textWebPassword" value="3" /></attr></declare-styleable>
