java如何解决这个错误：Android资源链接失败？
下面这两个代码在我的Android Studio项目的同一个主活动中
1）从智能手机重新录制音频，并在按下播放按钮时播放：
public class Main2Activity extends AppCompatActivity {
//Declare variables
Button btnRecord, btnStopRecord, btnPlay, btnStop;
//String pathSave ="";
private static String pathSave;
MediaRecorder mediaRecorder;
MediaPlayer mediaPlayer;
final int REQUEST_PERMISSION_CODE=1000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
//Request Runtime permission
if(!checkPermissionFromDevice()){
requestPermission();
}
//Init View
btnPlay = (Button) findViewById(R.id.btnPlay);
btnRecord = (Button) findViewById(R.id.btnStartRecord);
btnStop = (Button) findViewById(R.id.btnStop);
btnStopRecord = (Button) findViewById(R.id.btnStopRecord);
btnRecord.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick (View view){
if (checkPermissionFromDevice())
{
pathSave = Environment.getExternalStorageDirectory().getAbsolutePath()+"/"+ UUID.randomUUID().toString()+"audio_record.3gp";
setupMediaRecorder();
try{
mediaRecorder.prepare();
mediaRecorder.start();
} catch (IOException e){
e.printStackTrace();
}
btnPlay.setEnabled(false);
btnStop.setEnabled(false);
Toast.makeText(Main2Activity.this, "Recording...", Toast.LENGTH_SHORT).show();
}
else{
requestPermission();
}
}
});
btnStopRecord.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mediaRecorder.stop();
btnStopRecord.setEnabled(false);
btnPlay.setEnabled(true);
btnRecord.setEnabled(true);
btnStop.setEnabled(false);
}
});
btnPlay.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
btnStop.setEnabled(true);
btnStopRecord.setEnabled(false);
btnRecord.setEnabled(false);
mediaPlayer = new MediaPlayer();
try{
mediaPlayer.setDataSource(pathSave);
mediaPlayer.prepare();
} catch (IOException e){
e.printStackTrace();
}
mediaPlayer.start();
Toast.makeText(Main2Activity.this, "Playing...", Toast.LENGTH_SHORT).show();
}
});
btnStop.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
btnStopRecord.setEnabled(false);
btnRecord.setEnabled(true);
btnStop.setEnabled(false);
btnPlay.setEnabled(true);
if (mediaPlayer != null){
mediaPlayer.stop();
mediaPlayer.release();
setupMediaRecorder();
}
}
});
}
private void setupMediaRecorder(){
mediaRecorder = new MediaRecorder();
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mediaRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
mediaRecorder.setOutputFile(pathSave);
}
private void requestPermission() {
ActivityCompat.requestPermissions(this, new String[]{
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.RECORD_AUDIO
} ,REQUEST_PERMISSION_CODE);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode)
{
case REQUEST_PERMISSION_CODE:
{
if(grantResults.length>0 && grantResults[0]== PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText( this, "Permission Denied", Toast.LENGTH_SHORT).show();
}
}
break;
}
}
private boolean checkPermissionFromDevice(){
int write_external_storage_result = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
int record_audio_result = ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO);
return write_external_storage_result == PackageManager.PERMISSION_GRANTED &&
record_audio_result == PackageManager.PERMISSION_GRANTED;
}
2）保存创建音频文件的目录并将其转换为矢量：
String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/"+UUID.randomUUID().toString()+"audio_record.3gp";
public byte[] convert(String path) throws IOException {
FileInputStream fis = new FileInputStream(path);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
byte[] b = new byte[1024];
for (int readNum; (readNum = fis.read(b)) != -1; ) {
bos.write(b, 0, readNum);
}
byte[] bytes = bos.toByteArray();
return bytes;
}

该文件或资源不是名为com的文件或资源。实例appsom:integer/bottom_sheet_slide_duration）。 创建整数。项目的\res\values文件夹中的xml文件。在文件中创建整数：
