在此代码中定义4个按钮和xml文件，当用户点击开始按钮开始录制时，用户点击停止按钮停止录制然后类似播放和停止播放按钮 但问题是如何保存具有特定名称的特定音频文件

何时可以创建一个方法来保存文件，并提供用户名。当用户按下停止按钮时调用该方法。以下是示例代码：
private void saveRecording() {
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.set_file_name_dialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
// set prompts.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView.findViewById(R.id.editTextDialogUserInput);
Button cancel = (Button) promptsView.findViewById(R.id.save_cancel);
Button ok = (Button) promptsView.findViewById(R.id.save_ok);
// set dialog message
alertDialogBuilder
.setCancelable(false);
// create alert dialog
final AlertDialog alertDialog = alertDialogBuilder.create();
cancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
alertDialog.dismiss();
}
});
ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String newFileName = userInput.getText().toString();
if (newFileName != null && newFileName.trim().length() > 0) {
File newFile = new File(outputFileDir, newFileName);
File oldFile = new File(outputFileDir, oldFileName);
oldFile.renameTo(newFile);
alertDialog.dismiss();
}
}
});
// show it
alertDialog.show();
}
这是AlertDialog的布局文件：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="10dp" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Enter file name : "
android:textAppearance="?android:attr/textAppearanceLarge" />
<EditText
android:id="@+id/editTextDialogUserInput"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="20dp">
<requestFocus />
</EditText>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="2"
android:layout_marginTop="20dp">
<Button
android:id="@+id/save_cancel"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Cancel"
android:layout_weight="1"/>
<Button
android:id="@+id/save_ok"
android:layout_width="match_parent"

</LinearLayout>
</LinearLayout>
