接上篇在FileService.java中

/**
* 存储的SD卡中
* @param filename
* @param content
* @throws Exception
*/
public void saveToSDcard(String filename,String content) throws Exception
{
File file = new File(Environment.getExternalStorageDirectory(),filename);
FileOutputStream outputStream=new FileOutputStream(file);
outputStream.write(content.getBytes());
outputStream.close();
}

MainActivity.java中

saveToSDcard = (Button) findViewById(R.id.saveToSDcard);
saveToSDcard.setOnClickListener(new View.OnClickListener()
{

@Override
public void onClick(View v)
{
EditText filename = (EditText) findViewById(R.id.name);
EditText contain = (EditText) findViewById(R.id.contain);
String name = filename.getText().toString();
String textString = contain.getText().toString();
try
{
if (Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED))
{
fileService.saveToSDcard(name, textString);
Toast.makeText(getApplication(), "-------", 1).show();
}
} catch (Exception e)
{
// TODO: handle exception
e.printStackTrace();
}
}
});

Android之数据存入SD卡中
