小编nek*_*ouh的帖子

我想检查记录是否存在.

这是我尝试过的:

MainActivity.class

    public void onTextChanged(CharSequence s, int start, int before, int count) {

        System.out.println("Ontext changed " + new String(s.toString()));
        strDocumentFrom = s.toString();         

        if(s.toString().isEmpty()){

        } else {

             try{
                 strTransactionDate = dbHelper.getTransactionDateByDocumentNumber(strDocumentFrom);
                 //strTotalAmount = dbHelper.getTotalAmountByDocumentNumber(strDocumentFrom);
                 //strVan = dbHelper.getVanByDocumentNumber(strDocumentFrom);


                 //etTransactionDate.setText(strTransactionDate);
                 //etTotalAmount.setText(strTotalAmount);
                 //Log.d("Van", "" + strVan);
                 //etVan.setText(strVan);

             } catch (SQLiteException e) {
                 e.printStackTrace();
                 Toast.makeText(ReceivingStocksHeader.this, 
                         "Document number does not exist.", Toast.LENGTH_SHORT).show();
             }

        }

DBHelper.class

            // TODO DISPLAYING RECORDS TO TRANSRCVHEADER
        public String getTransactionDateByDocumentNumber(String strDocumentNumber){
            String[] columns = new String[]{KEY_TRANSACTIONDATE};

            Cursor c = myDataBase.query(TBL_INTRANS, 
                    columns, …

我从db到dropdown的显示数据有困难.

这是我尝试过的:

Model.php

        public function __construct()
        {
            parent::__construct();
        }

        function getAllGroups()
        {
            /*
            $query = $this->db->get('location');

            foreach ($query->result() as $row)
            {
                echo $row->description;
            }*/

            $query = $this->db->query('SELECT description FROM location');

            foreach ($query->result() as $row)
            {
                echo $row->description;
            }

            //echo 'Total Results: ' . $query->num_rows();
        }

Controller.php这样

    <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
    class Delivery_controller extends CI_Controller{
        public function __construct()
        {
            parent::__construct();
            $this->load->model('delivery_model');

        }
        public function index()
        {

            $data['title']= 'Warehouse - Delivery';
            $this->load->view('include/header',$data);
            $this->load->view('include/navbar',$data);
            $this->load->view('delivery_view', $data);
            $this->load->view('include/sidebar',$data); …

我想在我的绘画程序中加入一个颜色选择器.所以这里的任何人都已经做过这样的事情,请给我一些教程或一些代码来启动我.我真的需要得到添加这个的全部想法.我已经为绘图设置了画布,所以我想添加颜色选择器.欢迎任何想法.谢谢.

所以我现在所拥有的是:

但我想在左侧的文本框中包含图标搜索ICON SEARCH.

这是我的代码:

<form class="navbar-form pull-left form-search">
    <select>
        <option>Search patient by...</option>
        <option name="fname">Firstname</option>
        <option name="fname">Lastname</option>
        <option name="fname">Last follow up</option>
    </select>
    <div class="input-append">
        <input data-provide="typeahead" data-items="4"  type="text" 
           class="span2 search-query">
        <button class="btn">Search</button>
    </div>
</form>

那么任何想法如何实现这一目标？谢谢.

我已经为绘图设置了画布.我现在的问题是如何清除图纸.

试过这样做无济于事.

public void clear()
{
    circlePath.reset();
    mPath.reset();
    // Calls the onDraw() method
    //invalidate();
}

请在这里查看整个代码:

真的很感激任何帮助.

我正在研究拖放应用程序,一切正常,但我看到了一个问题.我有3个ImageViews,其中两个是可拖动的对象,另一个是放置目标.每当我将物体放在掉落目标以外的任何位置时,它就完全消失了!

以下是我使用的代码:

       ImageView iv1, iv2, iv3;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    initControls();

}

private void initControls() {
    // TODO Auto-generated method stub

    iv1 = (ImageView) findViewById (R.id.imageView1);
    iv2 = (ImageView) findViewById (R.id.imageView2);

    iv1.setTag("a");
    iv2.setTag("b");

    iv3 = (ImageView) findViewById (R.id.imageView3);
    iv1.setOnTouchListener(new MyTouchListener());
    iv2.setOnTouchListener(new MyTouchListener());
    iv3.setOnDragListener(new MyDragListener());

}

private final class MyTouchListener implements OnTouchListener {
    public boolean onTouch(View view, MotionEvent motionEvent) {
      if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) {
        ClipData data = ClipData.newPlainText("", "");
        DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(view);
        view.startDrag(data, shadowBuilder, …

我在下面的代码中有一个arrayoutofindexexception:

    ImageView[] bObject = new ImageView[9];

    private void getCorrectObject() {

    List<Integer> objects = new ArrayList<Integer>();
    objects.add(1);
    objects.add(2);
    objects.add(3);
    objects.add(4);
    objects.add(5);
    objects.add(6);
    objects.add(7);
    objects.add(8);
    objects.add(9);

    Collections.shuffle(objects);
    int correctObject =  objects.get(0);
    Log.d("test", String.valueOf(correctObject));

            bObject[correctObject + 1].setImageResource(R.drawable.stage1_4_object1);
    bObject[correctObject + 1].setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
                goToNextQuestion();
            }
        });
            }


           //TODO initControls
private void initControls() {

    bObject[0] = (ImageView) findViewById(R.id.bObject1Stage1_4);
    bObject[0].setImageResource(R.drawable.stage1_4_object2);
    bObject[1] = (ImageView) findViewById(R.id.bObject2Stage1_4);
    bObject[1].setImageResource(R.drawable.stage1_4_object2);
    bObject[2] = (ImageView) findViewById(R.id.bObject3Stage1_4);
    bObject[2].setImageResource(R.drawable.stage1_4_object2);
    bObject[3] = (ImageView) findViewById(R.id.bObject4Stage1_4);
    bObject[3].setImageResource(R.drawable.stage1_4_object2);
    bObject[4] = (ImageView) findViewById(R.id.bObject5Stage1_4);
    bObject[4].setImageResource(R.drawable.stage1_4_object2); …
