java - 如何使用 SQLITE 中的 String[] 替换 String[] 常量

我目前正在研究实现图像 Gridview 的通用图像加载器。我能够使用预定义的图像路径运行该项目。请帮助找到更好的解决方案。

基于this :

问题是我想使用数据库中保存的 URL 字符串集例如文件:///storage/sdcard0/folder/folder/folder/Image.jpg

现在我在 Activity A 中有这个:

public class LoadMainMenuActivty  extends BaseActivity {

    private static final String TEST_FILE_NAME = "Universal Image Loader @#&=+-_.,!()~'%20.png";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        new Constants(this.getBaseContext());


        setContentView(R.layout.load_main_menu_activity);

        File testImageOnSdCard = new File(Environment.getExternalStorageDirectory(), TEST_FILE_NAME);
        if (!testImageOnSdCard.exists()) {
            copyTestImageToSdCard(testImageOnSdCard);
        }

        new createFolders().execute();
        // Initialize Buttons
        Button btnOrderByList = (Button) findViewById(R.id.btnOrder);



        // Button Start Application
        // btnStartApp = (Button) findViewById(R.id.btnStartApp);
        btnOrderByList.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

                // Perform action on click
                // Launch Add New product Activity
                Intent i = new Intent(getApplicationContext(),
                        LoadMainGroupsActivty.class);
                // Closing all previous activities
                // i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(i);

            }
        });

    }

    public void onImageGridClick(View view) {
        Log.d("Error", "Here");
        Intent intent = new Intent(this, ImageGridActivity.class);
        intent.putExtra(Extra.IMAGES, IMAGES);
        startActivity(intent);
    }



    @Override
    public void onBackPressed() {
        imageLoader.stop();
        super.onBackPressed();
    }

    private void copyTestImageToSdCard(final File testImageOnSdCard) {
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    InputStream is = getAssets().open(TEST_FILE_NAME);
                    FileOutputStream fos = new FileOutputStream(testImageOnSdCard);
                    byte[] buffer = new byte[8192];
                    int read;
                    try {
                        while ((read = is.read(buffer)) != -1) {
                            fos.write(buffer, 0, read);
                        }
                    } finally {
                        fos.flush();
                        fos.close();
                        is.close();
                    }
                } catch (IOException e) {
                    L.w("Can't copy test image onto SD card");
                }
            }
        }).start();
    }

    /**
     * Background Async Task to Load all product by making HTTP Request
     * */
    class createFolders extends AsyncTask<String, String, String> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
        }

        protected String doInBackground(String... params) {
        //Creating folders in SD card


        }

    }

}

在常量类中:

public final class Constants {

    static DatabaseHandler db = new DatabaseHandler(getContext());
    static Context context;

    public Constants(Context context)
    {
        Constants.context = context;
    }

    static Context getContext()
    {
        return Constants.context;

    }

    ///public static final List<String> IMAGES = db.getImagePath();
    //Not sure with this

    static String[] paths = db.getImagePath();
    public static final String[] IMAGES = new String[] {
            // Heavy images

ImageGridActivity:

public class ImageGridActivity extends AbsListViewBaseActivity {

    String[] imageUrls;

    DisplayImageOptions options;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ac_image_grid);

        Bundle bundle = getIntent().getExtras();
        imageUrls = bundle.getStringArray(Extra.IMAGES);

            .build();

        listView = (GridView) findViewById(R.id.gridview);
        ((GridView) listView).setAdapter(new ImageAdapter());
        listView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                startImagePagerActivity(position);
            }
        });
    }

    private void startImagePagerActivity(int position) {
        Intent intent = new Intent(this, ImageGridActivity.class);
        intent.putExtra(Extra.IMAGES, imageUrls);
        intent.putExtra(Extra.IMAGE_POSITION, position);
        startActivity(intent);

    public class ImageAdapter extends BaseAdapter {
        @Override
        public int getCount() {
            return imageUrls.length;
        }

        @Override
        public Object getItem(int position) {
            return null;
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            final ImageView imageView;
            if (convertView == null) {
                imageView = (ImageView) getLayoutInflater().inflate(R.layout.item_grid_image, parent, false);
            } else {
                imageView = (ImageView) convertView;
            }

            imageLoader.displayImage(imageUrls[position], imageView, options);

            return imageView;
        }
    }
}

数据库处理程序:

@SuppressWarnings("null")
    public String[] getImagePath()
    {
        String [] paths = null;
        String selectQuery = "SELECT * FROM " + TABLE_PATH;



        SQLiteDatabase db = this.getWritableDatabase();
        Cursor cursor = db.rawQuery(selectQuery, null);

        int i = 1;
        // looping through all rows and adding to list
        if (cursor.moveToFirst()) {
            do {

                paths[i] = cursor.getString(0).toString();
                Log.d("getPathImage:", cursor.getString(0).toString());
                i++;
            } while (cursor.moveToNext());
        }

         return paths;



    }

老实说，我不知道如何或在哪里将从数据库返回的图像分配给IMAGES

public static final String[] IMAGES = new String[] {
"file:///storage/sdcard0/folder/folder/folder/Image.jpg",};

最佳答案 

public List<String> getImagePath()
{
    ArrayList<String> paths = new ArrayList<String>();
    String selectQuery = "SELECT * FROM " + TABLE_PATH;
    SQLiteDatabase db = this.getWritableDatabase();
    Cursor cursor = db.rawQuery(selectQuery, null);
    // looping through all rows and adding to list
    if (cursor.moveToFirst()) {
        do {

            paths.add(cursor.getString(0).toString());
            Log.d("getPathImage:", cursor.getString(0).toString());
        } while (cursor.moveToNext());
    }

     return paths;
}

然后

      DBHandler db = new DBHandler(ActivityName.this);
      db.open();
      ArrayList<String> list = getImagePath();

现在您可以在适配器类中使用该列表，并使用相同的通用图像加载器来显示图像。

附注，您可以从 sdcard 获取图像的路径并使用 UIL 显示图像。因此，您不需要为此目的使用数据库。

更多关于如何使用 UIL 的信息。

获取路径后

    ListView lv =(ListView) findViewById(R.id.listView);
    LazyAdapter adapter = new LazyAdapter(ActivityName.this,list);
    lv.setAdapter(adapter);

懒惰适配器

public class LazyAdapter extends BaseAdapter {

private Activity activity;
private ArrayList path;
private LayoutInflater inflater=null;
public ImageLoader imageLoader; 
DisplayImageOptions options;

public LazyAdapter(Activity a, ArrayList<String> paths) {
    activity = a;
    path = paths;
    inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

你检查一下UIL @的例子 Caching images and displaying

要从 SD 卡获取图像，请考虑您的文件夹包含图像。

private File[] listFile;
ArrayList<String> f = new ArrayList<String>();

public void getFromSdcard()
{
    File file = new File(android.os.Environment.getExternalStorageDirectory(),"MyFolder");

        if (file.isDirectory())
        {
            listFile = file.listFiles();
             for (int i = 0; i < listFile.length; i++)
            {
                f.add(listFile[i].getAbsolutePath());
            }   

        }
}
