Apache Pivot教程 – SuggestionPopup

在HTML中<input>总是可以提示之前输入过的内容，在Apache Pivot里面怎么做到呢?答案已经在标题里了，用SuggestionPopup

package text; import org.apache.pivot.wtk.*; import org.apache.pivot.collections.*; public class suggestion_popup implements Application { private Window window=null; private SuggestionPopup suggestionpopup=new SuggestionPopup(); //提示 public static void main(String [] args) { try { DesktopApplicationContext.main(suggestion_popup.class, args); } catch(Throwable err) { } } @Override public void startup(Display display, Map<String, String>properties) { window=new Window(); BoxPane panel=new BoxPane(); ArrayList<String>suggestions=new ArrayList<String>(); //建立提示内容列表 suggestions.setComparator(String.CASE_INSENSITIVE_ORDER); //设置列表属性 suggestions.add("hello"); //添加提示 suggestions.add("hi"); //添加提示 TextInput textinput1=new TextInput(); textinput1.setText("hello"); textinput1.getTextInputContentListeners().add(new TextInputContentListener.Adapter() //检测文本输入 { @Override public void textInserted(TextInput textinput, int index, int count) { String text=textinput.getText(); ArrayList<String>arr=new ArrayList<String>(); //正式建议列表 for(String str:suggestions) //遍历建议列表 { if(str.toUpperCase().startsWith(text.toUpperCase())) //如果简体文本由输入的内容开始 { arr.add(str); //添加到正式建议列表 } } if(arr.getLength()>0) { suggestionpopup.setSuggestionData(arr); //绑定正式提示窗 suggestionpopup.open(textinput); //打开建议提示 } } @Override public void textRemoved(TextInput arg0, int arg1, int arg2) { suggestionpopup.close(); //关闭提示窗 } }); panel.add(textinput1); PushButton button1=new PushButton(); button1.setButtonData("getIndex0"); button1.getButtonPressListeners().add(new ButtonPressListener() { @Override public void buttonPressed(Button button) { Alert.alert(Character.toString(textinput1.getCharacterAt(0)), window); } }); panel.add(button1); PushButton button2=new PushButton(); button2.setButtonData("getCharacterNumber"); button2.getButtonPressListeners().add(new ButtonPressListener() { @Override public void buttonPressed(Button button) { Alert.alert(Integer.toString(textinput1.getCharacterCount()), window); } }); panel.add(button2); PushButton button3=new PushButton(); button3.setButtonData("Information"); button3.getButtonPressListeners().add(new ButtonPressListener() { @Override public void buttonPressed(Button button) { textinput1.setSelection(1, 4); System.out.println(textinput1.getMaximumLength()); System.out.println(textinput1.getPrompt()); System.out.println(textinput1.getSelectedText()); System.out.println(textinput1.getSelectionLength()); System.out.println(textinput1.getSelectionStart()); System.out.println(textinput1.getSelection()); System.out.println(textinput1.getText()); System.out.println(textinput1.getText(0, 5)); System.out.println(textinput1.isEditable()); System.out.println(textinput1.isPassword()); textinput1.clearSelection(); textinput1.setPassword(true); } }); panel.add(button3); window.setContent(panel); window.setTitle("TextInput"); window.setMaximized(true); window.open(display); } @Override public boolean shutdown(boolean optional) { if(window!=null) { window.close(); } return false; } @Override public void suspend() { } @Override public void resume() { } }
