尝试从列表播放时出现 MediaPlayer 错误
MediaPlayer error when trying to play from list
我正在尝试构建一个录音机应用程序，MainActivity 记录，其他 activity 用于显示所有记录和媒体播放器的列表视图，媒体播放器出了点问题，在我构建第二个 activity 之前它运行良好，然后开始一些本机错误，所以我想我将构建第二个 activity 并修复它......仍然会出现一些本机错误。请帮助我修复它！
我记录了文件路径，似乎没问题。
Log.d(文件路径, "The path exist");

我的代码（记录Activity）：
public class RecordsActivity extends AppCompatActivity {
Button play;
static ListView recordList;
ArrayAdapter<String> listAdapter;
String recordToPlay;
MediaPlayer mp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_records);
mp = new MediaPlayer();
play = (Button) findViewById(R.id.playbutton);
recordList = (ListView) findViewById(R.id.list);
// Adapter with an ArrayList from the MainActivity that contains all the file names.
listAdapter = new ArrayAdapter<String>(RecordsActivity.this, R.layout.support_simple_spinner_dropdown_item, MainActivity.listRecord);
recordList.setAdapter(listAdapter);
recordList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//int chosenPosition = position;
recordToPlay = listAdapter.getItem(position);
//made that toast to check if the name of the file set properly, it looks like it is.
Toast.makeText(getApplicationContext(), recordToPlay+ " Chosen", Toast.LENGTH_LONG).show();
}
});
play.setOnClickListener(new View.OnClickListener() {
@Override

String filePath = Environment.getExternalStorageDirectory()+"/Recordings/"+recordToPlay;

我想你必须使用 recordToPlay = MainActivity.listRecord.get(position);
所以原因是：
以DateTime命名的文件，当格式是这样的：
String dateTime = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss aa", Locale.getDefault()).format(new Date());
MediaPlayer 由于某种原因出错。
所以我将其更改为：
String dateTime = new SimpleDateFormat("dd-MM-yyyy hh-mm-ss aa", Locale.getDefault()).format(new Date());
虽然我更喜欢hh:mm:ss
我正在尝试构建一个录音机应用程序，MainActivity 记录，其他 activity 用于显示所有记录和媒体播放器的列表视图，媒体播放器出了点问题，在我构建第二个 activity 之前它运行良好，然后开始一些本机错误，所以我想我将构建第二个 activity 并修复它......仍然会出现一些本机错误。请帮助我修复它！

我想你必须使用 recordToPlay = MainActivity.listRecord.get(position);
所以原因是： 以DateTime命名的文件，当格式是这样的：
String dateTime = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss aa", Locale.getDefault()).format(new Date());
MediaPlayer 由于某种原因出错。
所以我将其更改为：
String dateTime = new SimpleDateFormat("dd-MM-yyyy hh-mm-ss aa", Locale.getDefault()).format(new Date());
虽然我更喜欢hh:mm:ss
