2.4 AudioManager.java 的编写

package com.recorderactivity;import java.io.File;import java.io.IOException;import java.util.UUID;import android.media.MediaRecorder;/** * @ClassName:AudioManager * @Description:TODO * @author :吴雄峰 * @Date : 年5月日 下午:: * */public class AudioManager {private MediaRecorder mMediaRecorder;private String mDir;private String mCurrentPath;private static AudioManager mInstance;private String mCurrentFilePath;// 文件路径private boolean isPrepared;public AudioManager(String dir) {mDir = dir;}public interface AudioStateListener {void wellPrepared();}public AudioStateListener mListener;public void setOnAudioStateListener(AudioStateListener listener) {mListener = listener;}public static AudioManager getInstance(String dir) {if (mInstance == null) {synchronized (AudioManager.class) {if (mInstance == null) {mInstance = new AudioManager(dir);}}}return mInstance;}// 准备public void prepareAudio() {try {isPrepared = false;// 创建文件夹File dir = new File(mDir);if (!dir.exists()) {dir.mkdirs();}String fileName = generateFileName();File file = new File(dir, fileName);mCurrentFilePath = file.getAbsolutePath();mMediaRecorder = new MediaRecorder();// 设置输出文件mMediaRecorder.setOutputFile(file.getAbsolutePath());// 设置音频源mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);// 设置音频&#;式mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);// 设置音频编码mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);mMediaRecorder.prepare();mMediaRecorder.start();// 准备结束isPrepared = true;if (mListener != null) {mListener.wellPrepared();}} catch (IllegalStateException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}/*** @Description:随机生成文件的名称* @author :吴雄峰* */private String generateFileName() {return UUID.randomUUID().toString() &#; ".amr";}public int getVoiceLevel(int maxLevel) {if (isPrepared) {try {// getMaxAmplitude() 1-return maxLevel * mMediaRecorder.getMaxAmplitude() / &#; 1;} catch (Exception e) {// TODO: handle exception}}return 1;}public void release() {mMediaRecorder.stop();mMediaRecorder.release();mMediaRecorder = null;}public void cancel() {release();if (mCurrentFilePath != null) {File file = new File(mCurrentFilePath);file.delete();mCurrentFilePath = null;}}/*** @Description:* @author :吴雄峰* */public String getCurrentFilePath() {// TODO 自动生成的方法存根return mCurrentFilePath;}}

2.6 ViewHolder.java 的编写 （封装了，直接贴起来用，不用每次在adapter中写viewholder）

package com.recorderactivity;import android.R.integer;import android.content.Context;import android.graphics.Bitmap;import android.util.SparseArray;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import android.widget.TextView;/** * @ClassName:Viewholder * @Description:TODO viewholder基类 * @author :吴雄峰 * @Date : 年5月日 下午3:: * */public class Viewholder {private SparseArray<View> mViews;private int mPosition;private View mConvertView;/*** @Description:TODO* @author :吴雄峰* @Date : 年5月日 下午3::* */public Viewholder(Context context, ViewGroup parent, int layoutId,int position) {this.mPosition = position;this.mViews = new SparseArray<View>();mConvertView = LayoutInflater.from(context).inflate(layoutId, parent,false);mConvertView.setTag(this);}/*** * @Description:初始化viewholder* @author :吴雄峰**/public static Viewholder get(Context context, View convertView,ViewGroup parent, int layoutId, int position) {if (convertView == null) {return new Viewholder(context, parent, layoutId, position);} else {Viewholder viewholder = (Viewholder) convertView.getTag();viewholder.mPosition=position;return viewholder;}}/*** * @Description:通过viewID获取控件* @author :吴雄峰**/public <T extends View> T getView(int viewId) {View view = mViews.get(viewId);if (view == null) {view = mConvertView.findViewById(viewId);mViews.put(viewId, view);}return (T) view;}public View getConvertView() {return mConvertView;}/*** * @Description:设置textview 的&#;* @author :吴雄峰**/public Viewholder setText(int viewId,String text){TextView tv=getView(viewId);tv.setText(text);return this;}/*** * @Description:用setImageResource方法设置imageview的图片* @author :吴雄峰**/public Viewholder setImageViewResource(int viewId,int resId){ImageView imageView=getView(viewId);imageView.setImageResource(resId);return this;}/*** * @Description:用setImageBitmap方法设置imageview的图片* @author :吴雄峰**/public Viewholder setImageViewBitmap(int viewId,Bitmap bitmap){ImageView imageView=getView(viewId);imageView.setImageBitmap(bitmap);return this;}public Viewholder setImageViewUri(int viewId,String uri){ImageView imageView=getView(viewId);//imageLoader.getInstance().load(view,uri);return this;}}

2.7 listview 适配器的编写

package com.recorderactivity;import java.util.List;import android.content.Context;import android.util.DisplayMetrics;import android.view.View;import android.view.ViewGroup;import android.view.Window;import android.view.WindowManager;import android.widget.BaseAdapter;/** * @ClassName:ListViewAdapter * @Description:TODO * @author :吴雄峰 * @Date : 年5月日 下午1:: * */public class ListViewAdapter extends BaseAdapter {private int mMinItemWidth;private int mMaxItemWidth;private Context mContext;private List<RecorderEntity> mDatas;public ListViewAdapter(Context context, List<RecorderEntity> data) {// TODO 自动生成的构造函数存根this.mContext = context;this.mDatas = data;WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);DisplayMetrics outMetrics = new DisplayMetrics();wm.getDefaultDisplay().getMetrics(outMetrics);mMaxItemWidth = (int) (outMetrics.widthPixels * 0.7f);mMinItemWidth = (int) (outMetrics.widthPixels * 0.f);}/*** @author :吴雄峰* @Date : 年5月日 下午2::* @Description:*/@Overridepublic int getCount() {// TODO 自动生成的方法存根return mDatas.size();}/*** @author :吴雄峰* @Date : 年5月日 下午2::* @Description:*/@Overridepublic Object getItem(int position) {// TODO 自动生成的方法存根return mDatas.get(position);}/*** @author :吴雄峰* @Date : 年5月日 下午2::* @Description:*/@Overridepublic long getItemId(int position) {// TODO 自动生成的方法存根return position;}/*** @author :吴雄峰* @Date : 年5月日 下午2::* @Description:*/@Overridepublic View getView(int position, View convertView, ViewGroup parent) {Viewholder viewholder = new Viewholder(mContext, parent,R.layout.item_recorder, position);viewholder.setText(R.id.id_recorder_time,Math.round(mDatas.get(position).getmTime()) &#; """);//控制长度View lengh = viewholder.getView(R.id.id_recorder_lengh);ViewGroup.LayoutParams lp = lengh.getLayoutParams();lp.width = (int) (mMinItemWidth &#; mMaxItemWidth / f* mDatas.get(position).getmTime());return viewholder.getConvertView();}}

2.8 listview的实体类编写

package com.recorderactivity;/** * @ClassName:RecorderEntity * @Description:TODO * @author :吴雄峰 * @Date : 年5月日 下午1:: * */public class RecorderEntity {private float mTime;private String mFilePath;/*** @Description:TODO* @author :吴雄峰* @Date : 年5月日 下午1::* */public RecorderEntity(float time, String filePath) {super();this.mFilePath = filePath;this.mTime = time;}/*** @return mTime*/public float getmTime() {return mTime;}/*** @param mTime* 要设置的 mTime*/public void setmTime(float mTime) {this.mTime = mTime;}/*** @return mFilePath*/public String getmFilePath() {return mFilePath;}/*** @param mFilePath* 要设置的 mFilePath*/public void setmFilePath(String mFilePath) {this.mFilePath = mFilePath;}}

dialog的布局编写

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android=" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/dialog_loading_bg" android:gravity="center" android:orientation="vertical" android:padding="dp" > <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" > <ImageView android:id="@&#;id/id_dialog_recorder_icon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/recorder" android:visibility="visible" /> <ImageView android:id="@&#;id/id_dialog_recorder_voice" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/v1" android:visibility="visible" /> </LinearLayout> <TextView android:id="@&#;id/id_recorder_dialog_label" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="5dp" android:text="手指上滑，取消发送" android:textColor="#FFFFFF" android:visibility="visible" /></LinearLayout>

listview的item编写

<RelativeLayout xmlns:android=" xmlns:tools=" android:id="@&#;id/RelativeLayout1" android:layout_width="match_parent" android:layout_height="dp" android:layout_marginTop="5dp" > <ImageView android:id="@&#;id/id_icon" android:layout_width="dp" android:layout_height="dp" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:layout_marginRight="5dp" android:src="@drawable/icon" /> <FrameLayout android:id="@&#;id/id_recorder_lengh" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_toLeftOf="@id/id_icon" android:background="@drawable/chatto_bg_focused" > <View android:id="@&#;id/id_recorder_anim" android:layout_width="dp" android:layout_height="dp" android:layout_gravity="center_vertical|right" android:background="@drawable/adj" /> </FrameLayout> <TextView android:id="@&#;id/id_recorder_time" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginRight="3dp" android:layout_toLeftOf="@id/id_recorder_lengh" android:text="" android:textColor="#" /></RelativeLayout>
