Question

我有一个应用程序，可以在SD卡上记录和存储音频。它将其记录并保存在正确的位置，但将其保存为android.widget.EditText@random number。我使用EditText来获取文件名。

有谁知道如何让用户输入一些文本并保存文件。我以为我的代码是下面的代码，但没有......

try {
                    //Set user input as filename
                    String filename = getInput.toString();
                    // set the storage directory to SDcard
                    File storageDir = new File(Environment.getExternalStorageDirectory(), "audio");
                    storageDir.mkdir();
                    Log.d(APP_TAG, "Storage directory set to " + storageDir);

                    outfile = File.createTempFile(filename, ".3gp", storageDir);
                    //show filename
                    System.out.println("File is: "+outfile.getAbsolutePath());

                    // initiate recorder
                    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
                    recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
                    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
                    recorder.setOutputFile(outfile.getAbsolutePath());

                } catch (IOException e) {
                    Log.w(APP_TAG, "File not accessible ", e);
                } catch (IllegalArgumentException e) {
                    Log.w(APP_TAG, "Illegal argument ", e);
                } catch (IllegalStateException e) {
                    Log.w(APP_TAG, "Illegal state, call reset/restore", e);
                }
                startRecord();
            } else {
                stopRecord();

这是我更新的代码：

    //set filename to user input
                String filename = getInput.getText().toString()+".3gp";
                // show filename
                System.out.println("File is: " + filename);

                // initiate recorder
                recorder = new MediaRecorder();
                recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
                recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
                recorder.setOutputFile("/sdcard/audio/"+filename);
                recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);                    
                player.setDataSource(filename);

android.widget.EditText@random数字表示您的getInput是EditText，因此要获取其文本，您需要调用其getText（）方法，如下所示，

String filename = getInput.getText().toString();

Android商店使用输入文字录制音频？
