编辑文字密码切换Android [英] Edit text Password Toggle Android

问题描述

我试图在输入文本为密码"的编辑文本中向用户显示键入的密码.

我在这样的切换图标上实现了手势侦听器-

public boolean onTouch(View view, MotionEvent motionEvent) {
        switch (view.getId())
        {
            case R.id.ivPasswordToggle:

                switch ( motionEvent.getAction() ) {
                    case MotionEvent.ACTION_DOWN:
                        Toast.makeText(getContext(),"show",Toast.LENGTH_SHORT).show();
                        etPassword.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
                        break;
                    case MotionEvent.ACTION_UP:
                        etPassword.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD | InputType.TYPE_CLASS_TEXT);
                        Toast.makeText(getContext(),"hide",Toast.LENGTH_SHORT).show();
                        break;
                }
                break;
        }
        return true;
    }

我不知道出什么问题了，我们将不胜感激.

解决方案

自支持库v24.2.0起.您可以非常轻松地实现

您需要做的只是:

1. 将设计库添加到您的依存关系

   dependencies {
        compile "com.android.support:design:25.1.0"
   }
   

2. 将TextInputEditText与TextInputLayout

   结合使用

   <android.support.design.widget.TextInputLayout
       android:id="@+id/etPasswordLayout"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       app:passwordToggleEnabled="true">
   
       <android.support.design.widget.TextInputEditText
           android:id="@+id/etPassword"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:hint="@string/password_hint"
           android:inputType="textPassword"/>
   </android.support.design.widget.TextInputLayout>
   

passwordToggleEnabled属性将使密码切换出现

3. 在您的根目录布局中，不要忘记添加xmlns:app="http://schemas.android.com/apk/res-auto"

4. 您可以使用以下方法来自定义密码切换:

app:passwordToggleDrawable-可绘制以用作密码输入可见性切换图标.
app:passwordToggleTint-用于密码输入可见性切换的图标.
app:passwordToggleTintMode-用于应用背景色的混合模式.

I am trying to show user the typed password in edit text whose input type is text Password.

I implemented gesturelistener over the toggle icon like this-

public boolean onTouch(View view, MotionEvent motionEvent) {
        switch (view.getId())
        {
            case R.id.ivPasswordToggle:

                switch ( motionEvent.getAction() ) {
                    case MotionEvent.ACTION_DOWN:
                        Toast.makeText(getContext(),"show",Toast.LENGTH_SHORT).show();
                        etPassword.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
                        break;
                    case MotionEvent.ACTION_UP:
                        etPassword.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD | InputType.TYPE_CLASS_TEXT);
                        Toast.makeText(getContext(),"hide",Toast.LENGTH_SHORT).show();
                        break;
                }
                break;
        }
        return true;
    }

i dont know what is wrong, any help will be appreciated.

解决方案

Since the Support Library v24.2.0. you can achivie this very easy

What you need to do is just:

1. Add the design library to your dependecies

   dependencies {
        compile "com.android.support:design:25.1.0"
   }
   

2. Use TextInputEditText in conjunction with TextInputLayout

   <android.support.design.widget.TextInputLayout
       android:id="@+id/etPasswordLayout"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       app:passwordToggleEnabled="true">
   
       <android.support.design.widget.TextInputEditText
           android:id="@+id/etPassword"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:hint="@string/password_hint"
           android:inputType="textPassword"/>
   </android.support.design.widget.TextInputLayout>
   

passwordToggleEnabled attribute will make the password toggle appear

3. In your root layout don't forget to add xmlns:app="http://schemas.android.com/apk/res-auto"

4. You can customize your password toggle by using:

app:passwordToggleDrawable - Drawable to use as the password input visibility toggle icon.
app:passwordToggleTint - Icon to use for the password input visibility toggle.
app:passwordToggleTintMode - Blending mode used to apply the background tint.
