私は私のデバイスの私を回転させる場合は、すべてのFragmentとBTN機能はすべてこれが起こる理由を私は知らないなくなって。私はフラグメントを持っている場合、デバイスの回転をどのように処理するかを尋ねたい。助けてください...

ランドスケープモードの場合複数の画面をサポートするために複数のレイアウトを作成する必要があります。小さな画面サイズの通常の画面サイズ（ "デフォルト"）

RES /レイアウト小/ my_layout.xml //レイアウト

RES /レイアウト/ my_layout.xml //レイアウト

RES /レイアウト特大画面サイズの大画面サイズの-large/my_layout.xml //レイアウト

のres /レイアウト-XLARGE/my_layout.xml //レイアウト

のres /レイアウトXLARGE-ランド/ my_layout.xml /余分な横向きのレイアウト/レイアウト
