ボタンフィールドをクリックすると、この青色が表示されますsetChangeListener()。をオーバーライドnavigationClick()すると、正常に動作します。ただし、 で問題が発生しましたTouchEvent。

これがボタン呼び出しです。

newsbtn = new Custom_ButtonField(news, newsactive, newsactive);
        newsbtn.setChangeListener(new FieldChangeListener() {
            public void fieldChanged(Field field, int context) {
                Main.getUiApplication().pushScreen(
                        new Menu_PopupMenu(position));
            }
        });
        add(newsbtn);

ボタンの宣言です。

public class Custom_ButtonField extends ButtonField {
Bitmap mNormal;
Bitmap mFocused;
Bitmap mActive;

int mWidth;
int mHeight;

private int color = -1;
String text;

public Custom_ButtonField(Bitmap normal, Bitmap focused, Bitmap active) {
    super(CONSUME_CLICK | Field.FOCUSABLE | Field.FIELD_HCENTER
            | Field.FIELD_VCENTER);
    mNormal = normal;
    mFocused = focused;
    mActive = active;
    mWidth = mNormal.getWidth();
    mHeight = mNormal.getHeight();
    setMargin(0, 0, 0, 0);
    setPadding(0, 0, 0, 0);
    setBorder(BorderFactory.createSimpleBorder(new XYEdges(0, 0, 0, 0)));
    setBorder(VISUAL_STATE_ACTIVE,
            BorderFactory.createSimpleBorder(new XYEdges(0, 0, 0, 0)));
}

public Custom_ButtonField(String text, Bitmap normal, Bitmap focused,

    color = Color.WHITE;
    this.invalidate();

    else if (Display.getWidth() < 481 && Display.getWidth() > 320)
        fontcontent = 23;
    else

    Bitmap bitmap = null;

    }
    setBackground(BackgroundFactory.createBitmapBackground(bitmap));
    graphics.setFont(Font.getDefault().derive(Font.PLAIN, fontcontent));
    graphics.setColor(color);
    graphics.drawText(text, (mNormal.getWidth() - Font.getDefault()
            .getAdvance(text)) / 2, ((mNormal.getHeight() - Font
            .getDefault().getHeight()) / 2) + 10, DrawStyle.HCENTER
            | DrawStyle.VCENTER);
}

public int getPreferredWidth() {
    return mWidth;
}

public int getPreferredHeight() {
    return mHeight;
}

protected void layout(int width, int height) {
    setExtent(mWidth, mHeight);
}
}

オーバーライドdrawFocus(){//nothing here}しても、まだ青色に見えました。

ボタンがフォーカスされているときの画像です。

クリック時の画像はこちら。

This is one of the constructor.

public Custom_ButtonField(String text, Bitmap normal, Bitmap focused,
        Bitmap active, int color, long style) {
    super(style);
    this.color = color;
    this.text = text;
    mNormal = normal;
    mFocused = focused;
    mActive = active;
    mWidth = mNormal.getWidth();
    mHeight = mNormal.getHeight();
    setMargin(0, 0, 0, 0);
    setPadding(0, 0, 0, 0);
    setBorder(BorderFactory.createSimpleBorder(new XYEdges(0, 0, 0, 0)));
    setBorder(VISUAL_STATE_ACTIVE,
            BorderFactory.createSimpleBorder(new XYEdges(0, 0, 0, 0)));
    setBackground(VISUAL_STATE_NORMAL,
            BackgroundFactory.createBitmapBackground(normal));
    setBackground(VISUAL_STATE_FOCUS,
            BackgroundFactory.createBitmapBackground(focused));
    setBackground(VISUAL_STATE_ACTIVE,
            BackgroundFactory.createBitmapBackground(active));
}
