How to set edittext to show search button or enter button on keyboard?

set these two fields for showing search icon on keyboard.

            android:imeOptions="actionSearch"
            android:imeActionLabel="@string/search"

and also if you need to perform some action on keyboard search button click then you have to add the following code.

    etSearch.setOnEditorActionListener((v, actionId, event) -> {
        if (actionId == EditorInfo.IME_ACTION_SEARCH) {
              search();     // you can do anything
            return true;
        }
        return false;
    });

KOTLIN DEVELOPERS:

1. XML:

        <androidx.appcompat.widget.AppCompatEditText
            android:id="@+id/etSearch"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:fontFamily="@font/sans_medium"
            android:imeOptions="actionSearch"
            android:inputType="text" />

2. Class File:

etSearch.setOnEditorActionListener(object : TextView.OnEditorActionListener {
        override fun onEditorAction(v: TextView?, actionId: Int, event: KeyEvent?): Boolean {
            if (actionId == EditorInfo.IME_ACTION_SEARCH) {
                //hide Keyboard
                //do search here
                return true
            }
            return false
        }
    })

NOTES: With imeOptions="actionSearch" , don't forget to add inputType="text" or whatever you want to set as inputType in your XML. Otherwise you won't be able to see search icon on keyboard open.

Make your edittext like this.

    <EditText
        android:id="@+id/s_search"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textColor="#000"
        android:textSize="15dp"
        android:imeOptions="actionSearch"
        android:inputType="text"
        android:hint="Enter search" />

use this

<EditText
                android:id="@+id/editSearch"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:imeOptions="actionSearch"
                android:singleLine="true"

must add singleLine=true in your xml i hope my answer help you

set this attribute "imeOptions" in EditText view:

<EditText
     android:imeOptions="actionSearch"
     android:layout_width="match_parent"
     android:inputType="text"
     android:hint="Enter search"
     android:layout_height="wrap_content"
/>
