これは元のボタンの画像です。ボタンの背景は透明でした。
アプリに適用すると、ボタンは次のようになります。ボタンの左上をご覧ください。ボタンの背景が透明ではなく灰色になりました。
これがAndroid版のボタンです。
ボタンだけでなく、背景が透明な同じタイプのボタンもすべて。

ローダーはここにあります
private Bitmap news = Config_GlobalFunction.Bitmap("icon_news.png");
private Bitmap newsactive = Config_GlobalFunction
.Bitmap("icon_news_active.png");
if (left == 1) {
newsbtn = new Custom_ButtonField(news, newsactive, newsactive) {
protected boolean navigationClick(int status, int time) {
Main.getUiApplication().pushScreen(
new Menu_PopupMenu(thisid));
return true;
}
};
add(newsbtn);
} else if (left == 2) {
backbtn = new Custom_ButtonField(back, backctive, backctive) {
protected boolean navigationClick(int status, int time) {
Main.getUiApplication().popScreen(mainscreen);
return true;
}
};
add(backbtn);
}
if (left == 1) {
field = getField(1);
layoutChild(field, back.getWidth(), back.getHeight());
setPositionChild(field, 10, Height);
} else if (left == 2) {
field = getField(1);
layoutChild(field, news.getWidth(), news.getHeight());
setPositionChild(field, 10, Height);
}
このように設定すればlayoutChild(field, 60, 60);
問題ありません、後ろの灰色はもうありません。ただし、固定サイズを設定できず、動的サイズにする必要があります。
