我正在尝试使用此代码进行文件复制操作，但它给了我一个错误语法错误，插入“}”以完成 ClassBody MainActivity
在我放* *的地方请帮帮我
package com.AleXMan.taptaprevenge4songinstaller;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import android.os.Environment;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
File srcFolder = new File(Environment.getExternalStorageDirectory()+"/folder");
File destFolder = new File("/data/data/folder");
try{
if(!srcFolder.exists()){
Log.e("Error","Folder does not exist");
//just exit
}
else
{
InputStream in = new FileInputStream(srcFolder);
OutputStream out = new FileOutputStream(destFolder);
// Copy the bits from instream to outstream
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
}
}
finally{
}
**}**);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
如果您给我一个比我更好的代码，或者帮我解决这个错误，我将非常感谢您！
