エミュレータのSDカードのメディアに保存されている最初の画像の名前を取得しました。それに対応する画像を表示したいのですが。どうすればいいですか?
これがコードです
import android.app.Activity;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.util.Log;
import android.widget.ImageView;
import android.widget.TextView;
public class ClientActivity extends Activity {
ImageView imageView;
TextView textView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_client);
imageView = (ImageView) findViewById(R.id.imageView1);
textView = (TextView) findViewById(R.id.textview1);
String[] projection = new String[]{
MediaStore.Images.Media._ID,
MediaStore.Images.Media.BUCKET_DISPLAY_NAME,
MediaStore.Images.Media.DATE_TAKEN,
MediaStore.Images.Media.TITLE,
};
// Get the base URI for the People table in the Contacts content provider.
Uri images = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
Log.i("URI", images.toString());
// Make the query.
Cursor cur = managedQuery(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
projection, // Which columns to return
null, // Which rows to return (all rows)
null, // Selection arguments (none)
MediaStore.Images.Thumbnails.IMAGE_ID // Ordering
);
Log.i("ListingImages"," query count="+cur.getCount());
if (cur.moveToFirst()) {
String bucket;
String date;
String name;
int bucketColumn = cur.getColumnIndex(
MediaStore.Images.Media.BUCKET_DISPLAY_NAME);
int dateColumn = cur.getColumnIndex(
MediaStore.Images.Media.DATE_TAKEN);
int nameColumn = cur.getColumnIndex(
MediaStore.Images.Media.TITLE);
// Get the field values
bucket = cur.getString(bucketColumn);
date = cur.getString(dateColumn);
name = cur.getString(nameColumn);
// Do something with the values.
Log.i("ListingImages", " bucket=" + bucket
+ " name_taken=" + name);
}
}
}
どんな助けでも大歓迎です!
