Need to make double hint in EditText with TextInputLayout

Question

Here is the problem with double hint - TextInputLayout and EditText double hint issue

I need to do the same. I need two hints. One is a title of EditText, and second is a possible value if nothing wasn't input.

But unfortunately there is only one tag:

android:hint

Can I do something with it?

UPD1:

The answer was to set hint for EditText programatically and hint for TextInputLayout in xml.

        <android.support.design.widget.TextInputLayout
            android:layout_width="match_parent"
            android:hint="@string/prompt_quantity"
            android:layout_height="wrap_content">

            <EditText
                android:id="@+id/quantity"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:inputType="number"
                android:maxLines="1"
                android:singleLine="true" />

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

And

    quantityEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            quantityEditText.setHint(hasFocus ? "0" : "");
        }
    });

Answer 1

With the Material Components library you can use

• android:hint="Label" to add a floating label
• app:placeholderText="Placeholder Text" to add a placeholder in the EditText.

Use something like:

<com.google.android.material.textfield.TextInputLayout
    android:hint="Label"
    app:placeholderText="Placeholder Text"
    ..>

     <com.google.android.material.textfield.TextInputEditText />

</com.google.android.material.textfield.TextInputLayout>

Note: it requires at least the version 1.2.0-alpha03.

Try this way

xml layout

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_gravity="center_vertical"
              android:layout_width="match_parent"
              android:layout_height="wrap_content">
    <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/non_active_edit_text"
            android:focusable="false"
            android:gravity="right|center_vertical"
            android:hint="Right"
            android:paddingTop="4dp"
            android:background="@null"/>


    <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/active_edit_text"
            android:hint="Left"
            android:layout_gravity="center_horizontal"/>
</merge>

JAVA class

public class TwoHints extends RelativeLayout{

    EditText activeField;
    EditText nonActiveEditText;

    final CharSequence hint;
    public TwoHints(Context context, AttributeSet attrs) {
        super(context, attrs);
        LayoutInflater.from(context).inflate(R.layout.two_hints_edit_text, this);
        activeField = (EditText)findViewById(R.id.active_edit_text);
        nonActiveEditText = (EditText)findViewById(R.id.non_active_edit_text);
        hint = nonActiveEditText.getHint();
        activeField.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                nonActiveEditText.setHint(s.length() !=0 ? "" : hint);
            }

            @Override
            public void afterTextChanged(Editable s) {

            }
        });
    }
}

editetext for xml

<you.package.TwoHints
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/textView"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"/>

Answer 3

Just check your input and change the hint depending on that:

EditText editText = (EditText)findViewById(R.id.editText);
editText.addTextChangedListener(new TextWatcher() 
{
    @Override
    public void afterTextChanged(Editable s) 
    {
        if(editText.getText().toString().equals(""))
            editText.setHint("");
        else
            editText.setHint("Your normal hint");
    }
});
