如何使用PasswordToggleEnabled将DrawableLeft设置为EditText

Question

I've made a TextInputEditText for a PasswordField with a DrawableLeft as an icon, and then i added a PasswordToggleEnabled(true) .. this operation has deleted or hiden my DrawableLeft , Here's my code:

<android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:passwordToggleContentDescription="Show Password"
        app:passwordToggleEnabled="true"
        app:hintEnabled="false"
        android:id="@+id/signupPasswordlayout"
        app:passwordToggleTint="@color/edittexttint">
        <android.support.design.widget.TextInputEditText
            android:hint="Password"
            android:id="@+id/signupPassword"
            android:drawableLeft="@drawable/ic_password"
            android:drawablePadding="10dp"
            android:inputType="textPassword"
            android:drawableTint="@color/edittexttint"
            android:textSize="15sp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
        </android.support.design.widget.TextInputLayout>

so , is it possible to show both ( PasswordToggle and DrawableLeft ? ) thank you!

Answer 1

I'd not seen this exact behavior before, but looking at the source for TextInputLayout , it does attempt to preserve the user-set drawables when it applies the placeholder drawable for the password toggle. However, like most everything else in the support libraries to which its applicable, it handles them with relative positions - ie, start and end - rather than absolute - left and right .

The support libraries have always been notorious for breaking anything that specifies absolute directions or positions, so it's no surprise that that's the issue here, as well.

Simply change the attribute you're setting to drawableStart , instead of drawableLeft . Keep this in mind, too, for anything else involving a choice of absolute or relative positions and directions with the support libraries.
