这篇文章给大家分享的是有关Android如何实现点击持续录音，松开结束录音并实现随着分贝的大小改变图片的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
显示录音大小的DIALOG实现
public class VioceDomio {
private Context mContext;
private AlertDialog dialog ;
private AlertDialog.Builder adialogbuile;
private ImageView vioce_show;
public VioceDomio(Context mContext) {
this.mContext=mContext;
}
public void showRecordingDialog() {
adialogbuile = new AlertDialog.Builder(mContext, R.style.Theme_AudioDialog);
LayoutInflater inflater = LayoutInflater.from(mContext);
View view=inflater.inflate(R.layout.voice_chage,null);
vioce_show=(ImageView) view.findViewById(R.id.vioce_show);
adialogbuile.setView(view);
dialog = adialogbuile.create();
dialog.show();
dialog. getWindow().setLayout(500, 450);
}
public void HideRecordingDialog() {
if(dialog!=null && dialog.isShowing()) {
dialog.dismiss();
dialog=null;
}
}
public void ChangeRecordingDialog(double db) { //根据录音的分贝改变大小
if(db>=1 && db<=18) {
vioce_show.setImageResource(R.drawable.voicesearch_feedback001);
}else if(db>=19 && db<=37) {
vioce_show.setImageResource(R.drawable.voicesearch_feedback002);
}else if(db>=19 && db<=37) {
vioce_show.setImageResource(R.drawable.voicesearch_feedback003);
}
else if(db>=38 && db<=56) {
vioce_show.setImageResource(R.drawable.voicesearch_feedback004);
}else if(db>=57 && db<=75) {
vioce_show.setImageResource(R.drawable.voicesearch_feedback005);
}else if(db>=76 && db<=94) {
vioce_show.setImageResource(R.drawable.voicesearch_feedback006);
}else if(db>=95 && db<=100) {
vioce_show.setImageResource(R.drawable.voicesearch_feedback007);
}
}
}Dialog加载的XML页面实现
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="90dp" android:layout_marginTop="5dp" android:id="@+id/bianhua"> <ImageView android:id="@+id/vioce_show" android:layout_width="wrap_content" android:layout_height="50dp" android:layout_alignParentBottom="true" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:src="@drawable/voicesearch_feedback001" /> <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android:text="正在录音中" android:gravity="center" /> </RelativeLayout>
主界面的试下
activoti.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/speak" android:layout_width="wrap_content" android:layout_height="42dp" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:paddingLeft="10dp" android:layout_weight="0.62" android:background="@drawable/search_ba" android:drawableLeft="@drawable/speak_1" android:gravity="center" android:text="按住请讲话！！！" android:textSize="15sp" android:singleLine="true" android:visibility="gone" /> </LinearLayout >
MainActiovity.java实现
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activoti);
send=(Button) findViewById(R.id.send);
viocedomio=new VioceDomio(this);
speak.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
CountingThreadextends thend=new CountingThreadextends();
if(event.getAction()==MotionEvent.ACTION_DOWN) { //如果按钮处于按下状态
//录音
if(!Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED)) {
Toast.makeText(ChatActivity.this, "SD not ", Toast.LENGTH_SHORT).show();
return false;
}
String sound_path=time_path+"sound.amr";
try{
soundfile=new File(Environment.getExternalStorageDirectory().getCanonicalFile()+"/bishevoice/"+sound_path);
Log.d("send_filepath", Environment.getExternalStorageDirectory().getCanonicalFile()+"/bishevoice/"+sound_path);
mmedio=new MediaRecorder();
mmedio.setAudioSource(MediaRecorder.AudioSource.MIC);
mmedio.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mmedio.setOutputFile(soundfile.getAbsolutePath());
mmedio.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
try{
//创建文件，准备录制
soundfile.createNewFile();
mmedio.prepare();
}catch(IllegalStateException e) {
e.printStackTrace();
}
//开始录制
thend.start();
mmedio.start();
speak.setText("松开停止录音");
viocedomio.showRecordingDialog(); //显示录音的大小
final Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
viocedomio.ChangeRecordingDialog(Double.parseDouble(msg.obj.toString()));
}
};
new Thread(new Runnable() { //启动线程根据改变录音显示大小
@Override
public void run() {
// TODO Auto-generated method stub
while(mmedio!=null) {
double ratio = (double)mmedio.getMaxAmplitude() ;
double db = 0;// 分贝
if (ratio > 1)
db = 20 * Math.log10(ratio);
// Log.d(TAG,分贝值：+db);
// mHandler.postDelayed(mUpdateMicStatusTimer, SPACE);
Message msg=new Message();
msg.obj=db;
mHandler.sendMessage(msg);
}
}
}).start();
}catch(Exception e) {
e.printStackTrace();
}
}
if(event.getAction()==MotionEvent.ACTION_UP) { //如果是松开
if(soundfile != null && soundfile.exists()) { //停止录音
try {
mmedio.setOnErrorListener(null);
mmedio.setOnInfoListener(null);
mmedio.setPreviewDisplay(null);
mmedio.stop();
thend.interrupt();
//timetask.cancel();
}catch(Exception e) {
Log.i("Exception", Log.getStackTraceString(e));
}
mmedio.release();
mmedio=null;
speak.setText("按住请讲话！！！");
String content="";
if(content.isEmpty()) {
viocedomio.HideRecordingDialog(); //隐藏录音标志
Msg msg=new Msg(content,Msg.TYPE_SENT,Msg.TYPE_SENT_VOICE,Integer.toString(time_int),file_path);
msg.setChattype(0);
msglist.add(msg);
adapter.notifyDataSetChanged(); //当有新消息时，刷新listview中的显示
msgListView.setSelection(msglist.size()-1); //将listview定位到最后一行
}
}
}
return true;
}
