java无法在Android 2.1上加载静态文件
我需要将text
文件加载到内存中,该文件位于res/raw
目录中。这是我的代码:
package com.ggd543.安卓;
import 安卓.app.Activity;
import 安卓.content.res.Resources;
import 安卓.os.Bundle;
import 安卓.widget.TextView;
import java.io.IOException;
import java.io.InputStream;
public class FileActivity extends Activity {
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
loadText();
}
private void loadText() {
// InputStream is = Resources.getSystem().openRawResource(R.raw.text);
InputStream is = getResources().openRawResource(R.raw.text);
try {
byte[] buf = new byte[is.available()];
is.read(buf, 0, buf.length);
((TextView) findViewById(R.layout.main)).setText(new String(buf, "UTF-8"));
} catch (IOException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
}
}
}
}
当我在emulator上部署.apk
并启动它时,我得到了以下错误:

谁能给我提个建议吗

将文件移动到“资源”文件夹
然后像这样检索流
InputStream is = getAssets().open("fileName");
如果你有资产/mytxtfile。txt 然后fileName=“mytxtfile.txt”
