        android:textColorHint="#0092FF"/>
    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@color/black"/>
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <EditText
            android:id="@+id/password"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="#fff"
            android:padding="12dp"
            android:hint="密码"
            android:inputType="textPassword"
            android:singleLine="true"
            android:textColorHint="#FF0033"/>

        <CheckBox
            android:id="@+id/checkbox"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:button="@drawable/fuhe"/>
    </RelativeLayout>
</LinearLayout>

背景布局

LinearLayout的边框背景设置：

<shape xmlns:android="http://schemas.android.com/apk/res/android">
   <stroke  android:width="1dp" android:color="@color/black"/>
   <solid android:color="@color/white"/>
</shape>

密码的显示和隐藏设置：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_baseline_visibility_off_24" android:state_checked="false"/>
    <item android:drawable="@drawable/ic_baseline_visibility_24" android:state_checked="true"/>
</selector>

java代码设置

通过点击眼睛显示和隐藏EditText的密码

private void init(){
    checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            if (b){
                password.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
            }else {
                password.setTransformationMethod(PasswordTransformationMethod.getInstance());
            }
        }
    });
}
