Android商店使用输入文本记录的音频？ [英] Android store recorded audio using input text?

问题描述

我有记录并存储在SD卡音频的应用程序。它记录并在正确的地方保​​存，但其保存为android.widget.EditText@random号。我是用一个EditText来获取文件名。

有谁知道我可以让用户输入一些文字，并保存文件作为。我以为我到的东西与下面的code，但没有...

  {尝试
                    //设置用户输入的文件名
                    字符串文件名= getInput.toString（）;
                    //设置存储目录SD卡
                    文件storageDir =新的文件（Environment.getExternalStorageDirectory（），音频）;
                    storageDir.mkdir（）;
                    Log.d（APP_TAG，存储目录设置为+ storageDir）;                    OUTFILE = File.createTempFile（文件名，名为.3gp，storageDir）;
                    //显示文件名
                    的System.out.println（文件是：+ outfile.getAbsolutePath（））;                    //开始记录
                    recorder.setAudioSource（MediaRecorder.AudioSource.MIC）;
                    recorder.setOutputFormat（MediaRecorder.OutputFormat.THREE_GPP）;
                    recorder.setAudioEn codeR（MediaRecorder.AudioEn coder.AMR_NB）;
                    recorder.setOutputFile（outfile.getAbsolutePath（））;                }赶上（IOException异常五）{
                    Log.w（APP_TAG，文件无法访问，E）;
                }赶上（抛出：IllegalArgumentException五）{
                    Log.w（APP_TAG，非法的说法，E）;
                }赶上（IllegalStateException异常五）{
                    Log.w（APP_TAG，非法状态，呼叫复位/恢复，E）;
                }
                startRecord用于（）;
            }其他{
                STO precord（）;
 

---

这是我更新code：

  //设置文件名用户输入
                。字符串文件名= getInput.getText（）的toString（）+3GP。
                //显示文件名
                的System.out.println（文件是：+文件名）;                //开始记录
                记录=新MediaRecorder（）;
                recorder.setAudioSource（MediaRecorder.AudioSource.MIC）;
                recorder.setOutputFormat（MediaRecorder.OutputFormat.THREE_GPP）;
                recorder.setOutputFile（/ SD卡/音频/+文件名）;
                recorder.setAudioEn codeR（MediaRecorder.AudioEn coder.AMR_NB）;
                player.setDataSource（文件名）;
 

解决方案

android.widget.EditText@random数字表示你的 getInput 是的EditText ，因此，要获得它的文本，你需要调用它的getText（）方法，如下图所示，

 字符串文件名= getInput.getText（）的toString（）。
 

I have an app that records and stores the audio on the sdcard. It records and saves it in the right place, but saves it as android.widget.EditText@random number. I was using an EditText to get the filename.

Does anyone know how I can let the user enter some text and save the file as that. I thought I was onto something with the code below, but no...

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();

here is my updated code:

    //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);

解决方案

android.widget.EditText@random number indicates that your getInput is a EditText, So to get its text you need to call its getText() Method, like below,

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