问题描述

我试图在输入类型为文本密码的编辑文本中向用户显示输入的密码.

我在这样的切换图标上实现了手势监听器-

public boolean onTouch(View view, MotionEvent motionEvent) {开关(view.getId()){案例 R.id.ivPasswordToggle:开关(motionEvent.getAction()){案例 MotionEvent.ACTION_DOWN:Toast.makeText(getContext(),"show",Toast.LENGTH_SHORT).show();etPassword.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);休息;案例 MotionEvent.ACTION_UP:etPassword.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD | InputType.TYPE_CLASS_TEXT);Toast.makeText(getContext(),"hide",Toast.LENGTH_SHORT).show();休息;}休息;}返回真；}

我不知道是什么问题，任何帮助将不胜感激.

(针对AndroidX更新)

自支持库 v24.2.0 起.你可以很容易地做到这一点

你需要做的只是:

1. 将设计库添加到您的依赖项中

    依赖项 {实现com.google.android.material:material:1.2.1"}

2. 将 TextInputEditText 与 TextInputLayout

   结合使用

    <com.google.android.material.textfield.TextInputLayoutxmlns:app=http://schemas.android.com/apk/res-auto"android:id=@+id/etPasswordLayout"android:layout_width=match_parent"android:layout_height="wrap_content";app:passwordToggleEnabled="true">
   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 
   (updated for AndroidX)
   Since the Support Library v24.2.0. you can achivie this very easy
   What you need to do is just:
   
   Add the design library to your dependecies
    dependencies {
        implementation "com.google.android.material:material:1.2.1"
    }
   
   
   Use TextInputEditText in conjunction with TextInputLayout
    <com.google.android.material.textfield.TextInputLayout
        xmlns:app="http://schemas.android.com/apk/res-auto"
        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"/>
    </com.google.android.material.textfield.TextInputLayout>
   
   
   passwordToggleEnabled attribute will make the password toggle appear
   
   In your root layout don't forget to add  xmlns:app="http://schemas.android.com/apk/res-auto"
   
   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.
   More details in TextInputLayout documentation.
