問題描述

我試圖在輸入類型為文本密碼的編輯文本中向用戶顯示輸入的密碼.

我在這樣的切換圖標(biāo)上實現(xiàn)了手勢監(jiān)聽器-

public boolean onTouch(View view, MotionEvent motionEvent) {開關(guān)(view.getId()){案例 R.id.ivPasswordToggle:開關(guān)(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；}

我不知道是什么問題，任何幫助將不勝感激.

(針對AndroidX更新)

自支持庫 v24.2.0 起.你可以很容易地做到這一點

你需要做的只是:

1. 將設(shè)計庫添加到您的依賴項中

    依賴項 {實現(xiàn)com.google.android.material:material:1.2.1"}

2. 將 TextInputEditText 與 TextInputLayout

   結(jié)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.
    解決方案 
   (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.
