Androidのお話。
端末サイズによって同じアプリの同じ画面でも、IMEが出たりでなかったりすると障害が。
原因を調べると、以下のコードで処理がわかれていた。*1
/frameworks/base/services/java/com/android/server/InputMethodManagerService.java

// specified what should be done with it?
// We only do this automatically if the window can resize
// to accommodate the IME (so what the user sees will give
// them good context without input information being obscured
// by the IME) or if running on a large screen where there
// is more room for the target window + IME.

ふむふむ。
isLayoutSizeAtLeast(Configuration.SCREENLAYOUT_SIZE_LARGE)がtrueの時にIMEを表示するのか・・。*2
コメント部分を心もとない英語力で意訳すると
「画面おっきいんだぁ♪有効活用するためにIME出しちゃうね♪」
って感じです。たぶん。
ということで、画面サイズが画面サイズが480x640以上だとIMEが強制的に出るわけでした。*3
IME出したくないなら
getWindow.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
ってやってねって言っといた。
※画面サイズはgetDefaultDisplayで取れる値かな。たぶん・・。*4
