Potongan kode dari jawaban lain berfungsi, tetapi tidak selalu jelas di mana menempatkannya dalam kode, terutama jika Anda menggunakan AlertDialog.Builderdan mengikuti tutorial dialog resmi karena tidak menggunakan final AlertDialog ...atau alertDialog.show().
alertDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
Lebih disukai
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
Karena SOFT_INPUT_STATE_ALWAYS_VISIBLE akan menyembunyikan keyboard jika fokus beralih dari EditText, di mana SHOW_FORCED akan menjaga keyboard tetap ditampilkan sampai diberhentikan secara eksplisit, bahkan jika pengguna kembali ke layar beranda atau menampilkan aplikasi terbaru.
Di bawah ini adalah kode kerja untuk AlertDialog yang dibuat menggunakan tata letak khusus dengan EditText yang didefinisikan dalam XML. Ini juga mengatur keyboard untuk memiliki tombol "pergi" dan memungkinkannya untuk memicu tombol positif.
alert_dialog.xml:
<RelativeLayout
android:id="@+id/dialogRelativeLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<!-- android:imeOptions="actionGo" sets the keyboard to have a "go" key instead of a "new line" key. -->
<!-- android:inputType="textUri" disables spell check in the EditText and changes the "go" key from a check mark to an arrow. -->
<EditText
android:id="@+id/editText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:layout_marginBottom="16dp"
android:imeOptions="actionGo"
android:inputType="textUri"/>
</RelativeLayout>
