AlertDialog.Builder 和spinner

 AlertDialog.Builder

System.out.println("fdkddddddddddddddd");final EditText theDestination=new EditText(this);//placeLocation=new Location(provider);new AlertDialog.Builder(this)  .setTitle("请输入")  .setIcon(android.R.drawable.ic_dialog_info)  .setView(theDestination)  .setPositiveButton("确定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubString destination=theDestination.getText().toString();searchName(destination);}})  .setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stub}})  .show();

 

public void chooseRoute() {            new AlertDialog.Builder(Main.this)                    .setTitle(R.string.alert_title_route)                    .setAdapter(new ArrayAdapter<String>(Main.this,R.layout.item,R.id.textViewId,getRoute()),                    new OnClickListener() {    @Override    public void onClick(DialogInterface dialog, int which) {    // TODO Auto-generated method stub    routetag=routeList.get(which);    //EDITTEXT_SEARCH_ROUTE=routeList.get(which);    String dirRouteKey=routeList.get(which);    new AlertDialog.Builder(Main.this)    .setTitle("选择方向")                 .setAdapter(new ArrayAdapter<String>(Main.this,R.layout.item,R.id.textViewId,getDirection(dirRouteKey)),new OnClickListener() {    @Override    public void onClick(DialogInterface dialog, int which) {    // TODO Auto-generated method stub    directiondir=directionList.get(which);    editText_searchRoute.setText(directiondir);    getTag(directionList.get(which));    if(2==style){    getPoint(stoptagList);                //将记录保存到搜索框中    }    if(1==style){    //显示车辆信息。    busOnRoute_dir();    }                suggestions.saveRecentQuery(routetag+"#"+directiondir, null);    }    }).show();    }    }).show();                         }

这个xml文件就是用来定义文字的排版的，里面可以设置文件的大小，样式

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    ><TextView  android:id="@+id/textViewId"    android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:textSize="28dip"    /></LinearLayout>

 

spinner

public static final String[] toggleModeText;    public static final int[] toggleModeIcons;    public static final int[] toggleMode = {1,2, 3, 4 };    static {        toggleModeText = new String[4];        toggleModeText[0]="clear the layout";        toggleModeText[1] = "Buses on one route";        toggleModeText[2] = "Stops and predictions on one route";        toggleModeText[3] = "Favorite stops";        toggleModeIcons = new int[] {R.drawable.bus_all,R.drawable.bus_one, R.drawable.busstop_one, R.drawable.busstop_star };    }

 

spr_toggleMode = (Spinner) findViewById(R.id.predictionsOrLocations);        spr_toggleMode.setAdapter(getToggleModeSpinner());

/**     * 获取Adapter for Toggle Mode Spinner     *      * @return     */    private SpinnerAdapter getToggleModeSpinner() {        ArrayList<ToggleModeLineInfo> modeList = new ArrayList<ToggleModeLineInfo>();        int length = toggleMode.length;        for (int i = 0; i < length; i++) {            int j = toggleModeIcons[i];            String str = toggleModeText[i];            ToggleModeLineInfo lineInfo = new ToggleModeLineInfo(j, str);            modeList.add(lineInfo);        }        return new ToggleModeAdapter(this, modeList);    }

spr_toggleMode.setOnItemSelectedListener(new OnItemSelectedListener(){@Overridepublic void onItemSelected(AdapterView<?> arg0, View arg1,int arg2, long arg3) {// TODO Auto-generated method stub   switch (arg2) {case 1: style = 1; System.out.println("路线是"+routetag); System.out.println("方向是"+directiondir); busOnRoute_dir();  break;case 2: style = 2; showStopandprediction();     break;default:break;}}@Overridepublic void onNothingSelected(AdapterView<?> arg0) {// TODO Auto-generated method stub}          });
