[Android]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 _Android

相逢意气为君饮，系马高楼垂柳边。这篇文章主要讲述[Android]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相关的知识，希望能为你提供帮助。
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); } } }

【[Android]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】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="https://www.songbingjia.com/android/@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
