Android 如何使用setTransformationMethod（null）显示密码，同时保留眼睛图标

目前，我的密码输入文本字段设计如下

<android.support.design.widget.TextInputLayout
    android:layout_marginLeft="@dimen/trading_activity_horizontal_margin"
    android:layout_marginRight="@dimen/trading_activity_horizontal_margin"

    app:hintTextAppearance="@style/TradingWizardTextInputLayout"
    app:passwordToggleEnabled="true"
    android:id="@+id/password_text_input_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >
    <android.support.design.widget.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/wizard_password"
        android:id="@+id/password_edit_text"

        android:inputType="textPassword"
        android:imeOptions="actionNext|flagNoExtractUi" />
</android.support.design.widget.TextInputLayout>

<android.support.design.widget.TextInputLayout
                    android:id="@+id/password_text_input"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:hintEnabled="false"
                    android:layout_marginLeft="@dimen/dimen_18"
                    android:layout_marginRight="@dimen/dimen_18">
                    <EditText
                        android:textSize="16sp"
                        android:paddingTop="0dp"
                        android:id="@+id/password_edit_text"
                        android:textColor="@android:color/black"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:drawableRight="@drawable/ic_hide_password"
                        android:maxLines="1"
                        />
                </android.support.design.widget.TextInputLayout>

密码是可见的。但是，它也会使眼睛图标消失

<android.support.design.widget.TextInputLayout
                    android:id="@+id/password_text_input"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:hintEnabled="false"
                    android:layout_marginLeft="@dimen/dimen_18"
                    android:layout_marginRight="@dimen/dimen_18">
                    <EditText
                        android:textSize="16sp"
                        android:paddingTop="0dp"
                        android:id="@+id/password_edit_text"
                        android:textColor="@android:color/black"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:drawableRight="@drawable/ic_hide_password"
                        android:maxLines="1"
                        />
                </android.support.design.widget.TextInputLayout>

<android.support.design.widget.TextInputLayout
                    android:id="@+id/password_text_input"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:hintEnabled="false"
                    android:layout_marginLeft="@dimen/dimen_18"
                    android:layout_marginRight="@dimen/dimen_18">
                    <EditText
                        android:textSize="16sp"
                        android:paddingTop="0dp"
                        android:id="@+id/password_edit_text"
                        android:textColor="@android:color/black"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:drawableRight="@drawable/ic_hide_password"
                        android:maxLines="1"
                        />
                </android.support.design.widget.TextInputLayout>

如何使用

setTransformationMethod（null）

显示密码，同时保留眼睛图标？

而不是使用

app:passwordToggleEnabled="true"

<android.support.design.widget.TextInputLayout
                    android:id="@+id/password_text_input"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:hintEnabled="false"
                    android:layout_marginLeft="@dimen/dimen_18"
                    android:layout_marginRight="@dimen/dimen_18">
                    <EditText
                        android:textSize="16sp"
                        android:paddingTop="0dp"
                        android:id="@+id/password_edit_text"
                        android:textColor="@android:color/black"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:drawableRight="@drawable/ic_hide_password"
                        android:maxLines="1"
                        />
                </android.support.design.widget.TextInputLayout>

您可以设置“drawableRight”和touchListener以获得相同的效果。 代码是这样的

<android.support.design.widget.TextInputLayout
                    android:id="@+id/password_text_input"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:hintEnabled="false"
                    android:layout_marginLeft="@dimen/dimen_18"
                    android:layout_marginRight="@dimen/dimen_18">
                    <EditText
                        android:textSize="16sp"
                        android:paddingTop="0dp"
                        android:id="@+id/password_edit_text"
                        android:textColor="@android:color/black"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:drawableRight="@drawable/ic_hide_password"
                        android:maxLines="1"
                        />
                </android.support.design.widget.TextInputLayout>

XML

<android.support.design.widget.TextInputLayout
                    android:id="@+id/password_text_input"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:hintEnabled="false"
                    android:layout_marginLeft="@dimen/dimen_18"
                    android:layout_marginRight="@dimen/dimen_18">
                    <EditText
                        android:textSize="16sp"
                        android:paddingTop="0dp"
                        android:id="@+id/password_edit_text"
                        android:textColor="@android:color/black"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:drawableRight="@drawable/ic_hide_password"
                        android:maxLines="1"
                        />
                </android.support.design.widget.TextInputLayout>

并在活动中设置侦听器

<android.support.design.widget.TextInputLayout
                    android:id="@+id/password_text_input"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    app:hintEnabled="false"
                    android:layout_marginLeft="@dimen/dimen_18"
                    android:layout_marginRight="@dimen/dimen_18">
                    <EditText
                        android:textSize="16sp"
                        android:paddingTop="0dp"
                        android:id="@+id/password_edit_text"
                        android:textColor="@android:color/black"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:drawableRight="@drawable/ic_hide_password"
                        android:maxLines="1"
                        />
                </android.support.design.widget.TextInputLayout>

passwordEditText.setOnTouchListener(new ShowHidePassword());

希望这有帮助。

没有。这不会改变任何事情。眼睛图标上仍然有一个对角叉号，密码仍然不可见。

                    android:layout_height="wrap_content"
                    app:hintEnabled="false"
                    android:layout_marginLeft="@dimen/dimen_18"
                    android:layout_marginRight="@dimen/dimen_18">
