我在"res"文件夹中有一个名为"raw"的资源目录，但是我的代码仍然无法访问它。问题出现在尝试声明MediaPlayer变量时。
public class MainActivity extends AppCompatActivity {
private MediaPlayer pSong;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pSong = MediaPlayer.create(this,R.raw.rando);
Button playButton = (Button) findViewById(R.id.play);
playButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(MainActivity.this,"Play", Toast.LENGTH_SHORT).show();
}
});
}
}
