TextInputLayout开发文档

——与代码实现动画两种实现方式

第一种方式：类库

一、配置依赖包：

1.在app的build.gradle中，操作如下

2.dependencies {

compile'com.android.support.constraint:constraint-layout:1.0.2'

compile 'com.android.support:design:22.2.0'

compile 'com.android.support:appcompat-v7:22.2.0'

}

3.RebuildProject一下项目

二、代码开发

布局：

<?xml version="1.0"encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:focusable="true"
              android:focusableInTouchMode="true"
              android:orientation="vertical"
    >

    <android.support.design.widget.TextInputLayout
        android:id="@+id/usernameWrapper"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        >

        <EditText
            android:id="@+id/username"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            />

    </android.support.design.widget.TextInputLayout>

    <android.support.design.widget.TextInputLayout
        android:id="@+id/passwordWrapper"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/usernameWrapper"
        android:layout_marginTop="4dp"
        >

        <EditText
            android:id="@+id/password"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textPassword"
            android:maxLength="6"/>

    </android.support.design.widget.TextInputLayout>

    <Button
        android:id="@+id/btn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#666666"
        android:text="登录"
        android:textAllCaps="false"
        android:textColor="#ffffff"/>

</LinearLayout>
