1

1つのパッケージに2つのクラスがあり、1つはlcudi.Canvasを拡張し、もう1つはlwuit.Formを拡張します

フォームに 2 つのボタンを作成します

私の目的は、ボタンの 1 つが押されたときにキャンバスを表示することです。

私の考えでは、この関数はキャンバスを表示する必要があります。

setFullScreenMode(true); しかし、そうではありません。

これはキャンバスクラスです

あなたは混合lwuitjavax.microeditionて一緒にコードを書いています。

lwuit Displayそのため、制御を制御から制御に移す必要がありますjavax.microedition.Display。このためには、 を呼び出し javax.microedition.lcdui.Display.getDisplay(hh).setCurrent(m); た後に呼び出す必要がありsetFullScreenModeますactionListener
