触摸屏键盘无法正确显示
当用户将鼠标悬停在触摸屏键盘下方的编辑字段上时,不会显示。显示的是与键盘大小相同的白色区域。这是 BlackBerry Torch 上的问题。我希望使用下面的代码触摸屏键盘能够正确显示?
BasicEditField nameField =
new BasicEditField(
" "+Local.getInfo8()+ " : ", "", 100, BasicEditField.FILTER_DEFAULT)
{
private int iRectX = getFont().getAdvance(getLabel());
private int iRectWidth = backgroundButtonBitmap.getWidth() - iRectX - 4;
public int getPreferredHeight() {
return backgroundButtonBitmap.getHeight() / 2;
}
public void layout(int width, int height) {
//setExtent(width, getPreferredHeight());
super.layout(width, getPreferredHeight());
}
public void paint(Graphics g) {
g.setColor(Color.BLACK);
g.setBackgroundColor(Color.WHITE);
//g.drawRect(iRectX, 0, iRectWidth, 20);
super.paint(g);
}
};
When the user hovers over editfield below the touch screen keyboard does not display. What is displayed is a white area that is same size as keyboard. This is an issue on BlackBerry Torch. I would expect the touch screen keyboard to appear correctly using below code ?
BasicEditField nameField =
new BasicEditField(
" "+Local.getInfo8()+ " : ", "", 100, BasicEditField.FILTER_DEFAULT)
{
private int iRectX = getFont().getAdvance(getLabel());
private int iRectWidth = backgroundButtonBitmap.getWidth() - iRectX - 4;
public int getPreferredHeight() {
return backgroundButtonBitmap.getHeight() / 2;
}
public void layout(int width, int height) {
//setExtent(width, getPreferredHeight());
super.layout(width, getPreferredHeight());
}
public void paint(Graphics g) {
g.setColor(Color.BLACK);
g.setBackgroundColor(Color.WHITE);
//g.drawRect(iRectX, 0, iRectWidth, 20);
super.paint(g);
}
};

在显示屏幕上,方法 sublayout 被重写 -
protected void sublayout( int maxWidth, int maxHeight ) {
}
行 -
setExtent(maxWidth,Constants.BACKGROUND_IMAGE.getHeight());
导致问题。On the display screen, the method sublayout was being overriden -
protected void sublayout( int maxWidth, int maxHeight ) {
}
The line -
setExtent(maxWidth,Constants.BACKGROUND_IMAGE.getHeight());
is causing the issue.
