Text wrapping in a ListField row on BlackBerry
How do I wrap text in a ListField row? I am displaying an image on the left and text on the right. Some of the longer text goes out of the Li开发者_高级运维stField row, and I would like it to wrap instead of being cut off.
I also face the same problem as my requirement is also same as yours, but in cases where you are not using images, but still want to use a custom label field to pass some parameters you can use my way.
import net.rim.device.api.system.Bitmap;
import net.rim.device.api.ui.Color;
import net.rim.device.api.ui.Field;
import net.rim.device.api.ui.Font;
import net.rim.device.api.ui.Graphics;
import net.rim.device.api.ui.Keypad;
import net.rim.device.api.ui.component.LabelField;
public class MyCustomSubscriptionLabelField extends LabelField {
private Bitmap image = null;
private String customName = null;
private String key;
private String programName, startTime;
// Edited by vivek on 2010-11-18 to convert Basic Tv as Live tv i.e mapping
public MyCustomSubscriptionLabelField(String key, String customName,
long style) {
super("", FOCUSABLE);
if (customName == null)
this.customName = key;
else
this.customName = customName;
this.key = key;
}
public MyCustomSubscriptionLabelField(String programName, String startTime,
String customName, long style) {
super("", FOCUSABLE);
this.programName = programName;
this.startTime = startTime;
}
public void setText(String text, int offset, int length) {
// super.setText(customName, image.getWidth(), customName.length());
super.setText(text);
}
public void paint(Graphics graphics) {
super.paint(graphics);
}
public String getCustomName() {
return customName;
}
public String getKey() {
return key;
}
protected boolean navigationClick(int status, int time) {
fieldChangeNotify(0);
return true;
}
protected boolean keyChar(char character, int status, int time) {
if (character == Keypad.KEY_ENTER) {
fieldChangeNotify(0);
return true;
}
return super.keyChar(character, status, time);
}
public void setProgramName(String programName) {
this.programName = programName;
}
public String getProgramName() {
return programName;
}
public void setStartTime(String startTime) {
this.startTime = startTime;
}
public String getStartTime() {
return startTime;
}
}
to use this custom label field class use setText to set any long text ;
customSubscriptionLabelField[j]=
new CustomSubscriptionLabelField("","Value tht u want to pass and retrive",style);
customSubscriptionLabelField[j].setText("Any Long text will be wrapped to new line ",0,text.length());
Hope this will help u in some places
Hey I found one more solution to our problem . add image to hfm1 add labelfield to hfm2 now add hfm1 and hfm2 to a vfm now add this vfm to the screen this will act like a label field with image and text and most probably serve our purpose
I found an answer to this question over on the blackberry developer support forums and thought it might be useful to you: http://supportforums.blackberry.com/t5/Java-Development/Can-drawText-wrap-text-into-multiple-lines/m-p/258817#M42493
