Android TextInputLayout hint overlaps EditText hint

As i know, we can't do as your wish.

Because, TextInputLayout is designed to float the hint once it gets focused So, once it went up nothing will be there in the place holder. We can do your requirement with slight changes as below.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    tools:context="com.stackoverflow.MainActivity">


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="10dp"
        android:text="Label"
        android:textColor="@color/colorPrimary" />

    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:paddingLeft="10dp"
        app:hintEnabled="false">

        <android.support.v7.widget.AppCompatEditText
            android:layout_width="match_parent"
            android:layout_height="?actionBarSize"
            android:hint="Place Holder"
            />

    </android.support.design.widget.TextInputLayout>

</RelativeLayout>

.

Perfect One!!!

xml code

<android.support.design.widget.TextInputLayout
        android:id="@+id/inputLayoutPhone"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="24dp"
        android:hint="Phone Number">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/edtPhone"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="+91"
            android:inputType="phone" />
</android.support.design.widget.TextInputLayout>

Kotlin code

 edtPhone.hint=""
 edtPhone.onFocusChangeListener = View.OnFocusChangeListener { _, hasFocus ->
        inputLayoutPhone.isHintEnabled = hasFocus
        if(hasFocus){
            edtPhone.hint="+91"
        }else{
            edtPhone.hint= "Phone Number"
        }
    }

Java code

edtPhone.setHint("");
    edtPhone.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View view, boolean hasFocus) {
            if (hasFocus){
                edtPhone.setHint("+91");
            }else{
                edtPhone.setHint("Phone Number");
            }

        }
    });

Now the material components (alpha03) have support for placeholder text:

  dependencies {
    // ...
    implementation 'com.google.android.material:material:1.2.0-alpha03'
    // ...
  }

  <com.google.android.material.textfield.TextInputLayout
      ...
      app:placeholderText="Placeholder text">
