Android怎样实现仿微信录音功能

这篇文章主要介绍了Android怎样实现仿微信录音功能，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

实现方法：

1.在xml文件中添加

2.别忘了申请录音权限

AndPermission.with(MainActivity.this)  .permission(Manifest.permission.RECORD_AUDIO,Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE)  .onGranted(permissions -> {   showSelect();  })  .onDenied(permissions -> {   Toast.makeText(MainActivity.this,"请同意录音权限",Toast.LENGTH_SHORT).show();  })  .start();private void showSelect() { SoundTextView recordAudio = findViewById(R.id.record_audio); recordAudio.setOnRecordFinishedListener(new SoundTextView.OnRecordFinishedListener() {  @Override  public void newMessage(String path, int duration) {  int index = path.lastIndexOf("/");  String fileName = path.substring(index + 1);  Log.e("录音文件", "path=: "+path );  } }); }

使用方法如上非常简单：

主要的类

package ant.muxi.com.audiodemo.view; import android.app.Activity;import android.app.Dialog;import android.content.Context;import android.os.Environment;import android.os.Handler;import android.os.Message;import android.util.AttributeSet;import android.util.Log;import android.view.MotionEvent;import android.widget.TextView;import android.widget.Toast;import androidx.appcompat.widget.AppCompatTextView;import java.io.File;import ant.muxi.com.audiodemo.R;import ant.muxi.com.audiodemo.audio.ProgressTextUtils;import ant.muxi.com.audiodemo.audio.RecordManager;public class SoundTextView extends AppCompatTextView { private Context mContext; private Dialog recordIndicator; private TextView mVoiceTime; private File file; private String type = "1";//默认开始录音 type=2，录音完毕 RecordManager recordManager; File fileto; int level; private long downT; String sountime; public SoundTextView(Context context) { super(context); init(); } public SoundTextView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); this.mContext = context; init(); } public SoundTextView(Context context, AttributeSet attrs) { super(context, attrs); this.mContext = context; init(); } private void init() { recordIndicator = new Dialog(getContext(), R.style.jmui_record_voice_dialog); recordIndicator.setContentView(R.layout.jmui_dialog_record_voice); mVoiceTime = (TextView) recordIndicator.findViewById(R.id.voice_time); file = new File(Environment.getExternalStorageDirectory() + "/recoder.amr"); fileto = new File(Environment.getExternalStorageDirectory() + "/recoder.mp3"); recordManager = new RecordManager(  (Activity) mContext,  String.valueOf(file),  String.valueOf(fileto)); recordManager.setOnAudioStatusUpdateListener(new RecordManager.OnAudioStatusUpdateListener() {  @Override  public void onUpdate(double db) {  //得到分贝  if (null != recordIndicator) {   level = (int) db;   handler.sendEmptyMessage(0x111);  }  } }); } Handler handler = new Handler() { @Override public void handleMessage(Message msg) {  super.handleMessage(msg);  switch (msg.what) {  case 0x111:   sountime = ProgressTextUtils.getSecsProgress(System.currentTimeMillis() - downT);   long time = System.currentTimeMillis() - downT;   mVoiceTime.setText(ProgressTextUtils.getProgressText(time));   //判断时间   judetime(Integer.parseInt(sountime));   break;  } } }; public void judetime(int time) { if (time > 14) {  //结束录制  Toast.makeText(mContext, "录音不能超过十五秒", Toast.LENGTH_SHORT).show();  recordManager.stop_mp3();  new Thread() {  @Override  public void run() {   super.run();   recordManager.saveData();   finishRecord(fileto.getPath(), sountime);  }  }.start();  recordIndicator.dismiss();  type = "2"; } } @Override public boolean onTouchEvent(MotionEvent event) { int action = event.getAction(); switch (action) {  case MotionEvent.ACTION_DOWN:  if (type.equals("1")) {   //开始发送时间   downT = System.currentTimeMillis();   recordManager.start_mp3();   recordIndicator.show();  } else {   Log.e("-log-", "您已经录制完毕: ");  }  return true;  case MotionEvent.ACTION_UP:  if (type.equals("1")) {   try {   if (Integer.parseInt(sountime) > 2) {    recordManager.stop_mp3();    new Thread() {    @Override    public void run() {     super.run();     recordManager.saveData();     finishRecord(fileto.getPath(), sountime);    }    }.start();    if (recordIndicator.isShowing()) {    recordIndicator.dismiss();    }    type = "2";   } else {    recordManager.stop_mp3();    if (recordIndicator.isShowing()) {    recordIndicator.dismiss();    }    sountime = null;    Toast.makeText(mContext, "录音时间少于3秒，请重新录制", Toast.LENGTH_SHORT).show();   }   } catch (Exception e) {   recordManager.stop_mp3();   if (recordIndicator.isShowing()) {    recordIndicator.dismiss();   }   sountime = null;   Toast.makeText(mContext, "录音时间少于3秒，请重新录制", Toast.LENGTH_SHORT).show();   }  }  break;  case MotionEvent.ACTION_CANCEL:  if (recordIndicator.isShowing()) {   recordIndicator.dismiss();  }  break; } return super.onTouchEvent(event); } //录音完毕加载 ListView item private void finishRecord(String path, String time) { if (onRecordFinishedListener != null) {  onRecordFinishedListener.newMessage(path, Integer.parseInt(time));  type = "1"; } //发送语音 // Toasts.toast(getContext(),"您已经录完了一条语音"+myRecAudioFile); } private OnRecordFinishedListener onRecordFinishedListener; public void setOnRecordFinishedListener(OnRecordFinishedListener onRecordFinishedListener) { this.onRecordFinishedListener = onRecordFinishedListener; } public interface OnRecordFinishedListener { void newMessage(String path, int duration); }}
