[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

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

  1. 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 >
  2. MainActiovity.java实现

    protected void onCreate(Bundle savedInstanceState) {
