null mMediaPlayer.isPlaying()){mMediaPlayer.pause();isPause true;}}public static void resume(){if(mMediaPlayer ! null isPause){mMediaPlayer.start();isPause false;}}public static void release(){if(mMediaPlayer ! null){mMediaPlayer.release();mMediaPlayer null;}}}三、DialogManager封装封装了6个方法1. showRecordingDialog()用来设置Diaog布局拿到控件的引用显示Dialog。2. recording()更改Dialog状态为录音中状态。3. wantToCancel()更改Dialog状态为想要取消状态。4. tooShort()更改Dialog状态为录音时长过短状态。5. dismissDialog()移除Dialog。6. updateVoiceLevel()用来更新音量图片。代码import android.app.Dialog;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.widget.ImageView;import android.widget.TextView;import com.tiddlerliu.wxrecorder.R;/*** Dialog管理类*/public class DialogManager {private Dialog mDialog;private ImageView mIcon;private ImageView mVoice;private TextView mLabel;private Context mContext;public DialogManager(Context context) {mContext context;}/*** 显示Dialog*/public void showRecordingDialog(){//将布局应用于DialogmDialog new Dialog(mContext, R.style.Theme_AudioDialog);LayoutInflater inflater LayoutInflater.from(mContext);View view inflater.inflate(R.layout.dialog_recorder,null);mDialog.setContentView(view);//成员控件赋值mIcon (ImageView) mDialog.findViewById(R.id.recorder_dialog_icon);mVoice (ImageView) mDialog.findViewById(R.id.recorder_dialog_voice);mLabel (TextView) mDialog.findViewById(R.id.recorder_dialog_label);mDialog.show();}public void recording(){if(mDialog !
