我必须设计布局,使整个布局应该滚动和内部布局我必须在Grid表单中显示相关内容所以我决定使用GridView.但问题是我无法在GridView里面使用ScrollView我已阅读文档(文档也说我们应该也不要GridView在里面使用ScrollView)但是我必须这样做,所以请任何关于此的请给我一些想法.谢谢

我已经Dialog在我的Andorid 应用程序中用于显示广告.但是我必须显示这个Dialog大约50dp来自buttom的顶部所以我认为我们应该设置DialogGravity buttom并设置它的buttom边距50dp.但我不能使用保证金.所以Dialog请建议我如何解决这个问题.

XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/popup_element"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/dialogback"
    android:orientation="vertical" >

    <WebView
        android:id="@+id/webView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

Java的:

final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));
LayoutInflater inflator = (LayoutInflater) getApplicationContext()
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflator.inflate(R.layout.ad, null, false);
dialog.setContentView(view);
dialog.getWindow().setGravity(Gravity.BOTTOM);
dialog.setCancelable(true);
WebView webView = (WebView) dialog.findViewById(R.id.webView);
webView.loadUrl("");
webView.setWebViewClient(new MyWebViewClient());
webView.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        dialog.dismiss();
    }
});
dialog.show();

我正在拍摄快照并制作缩略图,然后分享这张图片.但缩略图显示全黑.我使用了以下代码

Bitmap bitmap;
View v1 = v.getRootView();
v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
String url = Images.Media.insertImage(
mContext.getContentResolver(), bitmap, "title", null);

任何人都可以告诉我这段代码有什么问题.

编辑

private View.OnClickListener shareListener = new View.OnClickListener() {
        public void onClick(View v) {
            Bitmap bitmap;
            View v1 = v.getRootView();
            v1.setDrawingCacheEnabled(true);
            bitmap = Bitmap.createBitmap(v1.getDrawingCache());
            String url = Images.Media.insertImage(
                    mContext.getContentResolver(), bitmap, "title", null);
            v1.setDrawingCacheEnabled(false);
            Activity activity = (Activity) getContext();
            Intent share = new Intent(Intent.ACTION_SEND);
            share.setType("image/jpeg");
            share.putExtra(Intent.EXTRA_STREAM, Uri.parse(url));
            activity.startActivity(Intent.createChooser(share,
                    "Share"));

        }

    };

我刚刚创建了数据库,它默认存储在data/data/database文件夹中.现在我想在sdcard中存储数据库,我使用了以下代码.请指示我必须在哪里添加代码.谢谢

码:

    public class DataBaseHandler {
    SQLiteDatabase database;
    private static DataBaseHandler obj;
    private final String TABLE_NAME = "main_db";
    private final String COLUMN_FIRST = "_id";
    MovieDetails md = new MovieDetails();

    private DataBaseHandler(Context context) {
        DataBase dbobj = new DataBase(context, "Id_db.db", null, 1);
        database = dbobj.getWritableDatabase();
    }

    public static DataBaseHandler getinstance(Context context) {
        if (obj == null) {
            obj = new DataBaseHandler(context);
        }
        return obj;
    }

    public void insertData(String id) {
        try {
            ContentValues values = new ContentValues();
            values.put(COLUMN_FIRST, id);
            database.insert(TABLE_NAME, null, …

我对这个简单的程序感到困惑.我必须在数组中找到第三大的no.我已经完成了一些代码,但是在第三大代码中只获得第二大没有问题,所以请告诉我这个解决方案有什么问题:

class ArrayExample {
    public static void main(String[] args) {
        int secondlargest = Integer.MIN_VALUE;
        int thirdlargest = Integer.MIN_VALUE;
        int largest = Integer.MIN_VALUE;
        Scanner input = new Scanner(System.in);
        System.out.println("Enter array values: ");
        int arr[] = new int[5];
        for (int i = 0; i < arr.length; i++) {
            arr[i] = input.nextInt();
            if (largest < arr[i]) {
                secondlargest = largest;
                largest = arr[i];
            }
            if (secondlargest < arr[i] && largest != arr[i]) {
                thirdlargest = secondlargest;
                secondlargest = arr[i];
                if (thirdlargest < arr[i] …

我写了一些用于删除数据库文件夹的代码.它删除数据库但也抛出错误.请建议我如何解决这个问题.

删除数据库的代码

public void deleteDB() {
        try {
            File db_path = new File(
                    "/data/data/pacakge_name/databases/mydatabase_db.db");
            db_path.delete();
            System.out
                    .println("Database deleted successfully================================");
        } catch (Exception e) {
            // TODO: handle exception
            Log.e("Error==", e.toString());
        }
    }
Cursor cursor = handler.getCategoryData("1");
                        if (cursor.moveToFirst()) {
                            System.out
                                    .println("database has data................................");
                        } else {
                            System.out
                                    .println("database has no data.............................");
                            LiveTVCategoryParser category_parser = new LiveTVCategoryParser();
                            category_parser.category_parser(Splash.this, "1",
                                    "live_root");
                        }

我想在Android中使用Gama组件来使我们的应用程序变好.我已经下载了Gama jar甚至它抛出错误.我已经关注了以下链接http://developer.digitalaria.com/devguide/gama/en/gama/tile_android .php.

Java的

import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import com.digitalaria.gama.tile.Tile;

public class GamaAndroidActivity extends Activity {
    Button button;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

}
