本文示例主要實現了Android獲取assets文件夾中的數據并將其寫入到SD卡中，該程序實現的步驟主要為：首先讀取assets文件夾中的數據庫，再將其寫入到SD存儲卡中。
完整示例代碼如下：
import java.io.File;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import android.content.Context;/*將assets文件夾下的數據庫寫入SD卡中 * @author Dave */public class WriteToSD { private Context context; String filePath = android.os.Environment.getExternalStorageDirectory()+"/weather"; public WriteToSD(Context context){ this.context = context; if(!isExist()){ write(); } } private void write(){ InputStream inputStream; try { inputStream = context.getResources().getAssets().open("addressId.db"); File file = new File(filePath); if(!file.exists()){ file.mkdirs(); } FileOutputStream fileOutputStream = new FileOutputStream(filePath + "/database.db"); byte[] buffer = new byte[512]; int count = 0; while((count = inputStream.read(buffer)) > 0){ fileOutputStream.write(buffer, 0 ,count); } fileOutputStream.flush(); fileOutputStream.close(); inputStream.close(); System.out.println("success"); } catch (IOException e) { e.printStackTrace(); } } private boolean isExist(){ File file = new File(filePath + "/database.db"); if(file.exists()){ return true; }else{ return false; } }}新聞熱點
