다른 답변에서 코드 조각이 작동,하지만 당신은을 사용하는 경우 특히, 코드에 배치 할 위치를 항상 명확하지 않다 AlertDialog.Builder과 다음 공식 대화 튜토리얼 은 사용하지 않기 때문에 final AlertDialog ...나 alertDialog.show().
alertDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
~보다 바람직하다
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
SOFT_INPUT_STATE_ALWAYS_VISIBLE은 포커스가 EditText에서 멀어지면 키보드를 숨기므로 SHOW_FORCED는 사용자가 홈 화면으로 돌아가거나 최근 앱을 표시하더라도 키보드가 명시 적으로 해제 될 때까지 키보드를 계속 표시합니다.
다음은 XML로 정의 된 EditText를 가진 사용자 정의 레이아웃을 사용하여 생성 된 AlertDialog의 작업 코드입니다. 또한 키보드에 "go"키가 있도록 설정하고 양수 버튼을 트리거 할 수 있습니다.
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"
