android 读取assert文件夹和raw文件下数据

package com.example.readassert;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import android.os.Bundle;

import android.app.Activity;

import android.util.Log;

import android.view.Menu;

import android.view.View;

import android.widget.Toast;

public class MainActivity extends Activity {

private static final String TAG="ReadAssert";

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

findViewById(R.id.readtxtBtn).setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View arg0) {

// TODO Auto-generated method stub

try {

//assert文件夹下的文件info.txt

InputStream is=getResources().getAssets().open("info.txt");

InputStreamReader isr=new InputStreamReader(is,"utf-8");

BufferedReader bfr=new BufferedReader(isr);

String in="";

while((in=bfr.readLine())!=null){

Toast.makeText(MainActivity.this,

in, Toast.LENGTH_LONG).show();

}

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

});

}

}

读取raw文件夹下的数据：

package com.example.readassert;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import android.os.Bundle;

import android.app.Activity;

import android.util.Log;

import android.view.Menu;

import android.view.View;

import android.widget.Toast;

public class MainActivity extends Activity {

private static final String TAG="ReadAssert";

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

findViewById(R.id.readtxtBtn).setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View arg0) {

// TODO Auto-generated method stub

try {

InputStream is=getResources().openRawResource(R.raw.info);

InputStreamReader isr=new InputStreamReader(is,"utf-8");

BufferedReader bfr=new BufferedReader(isr);

String in="";

while((in=bfr.readLine())!=null){

Toast.makeText(MainActivity.this, bfr.readLine(), Toast.LENGTH_LONG).show();

}

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

});

}

}

在res这个资源文件下，在R.java下都会自动生成id
