android 仪表盘 示例源码

简单的基本功能，实测可行。 核心代码：package com.sharpandroid.music.activity;import java.io.IOException;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.Button;import android.widget.ImageButton;import android.widget.SeekBar;import android.widget.TextView;import com.sharpandroid.music.R;import com.sharpandroid.music.StreamingMediaPlayer;public class MediaPlayer extends Activity { private Button streamButton; private ImageButton playButton; private boolean isPlaying; private TextView playTime; private StreamingMediaPlayer audioStreamer; @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); initControls(); } private void initControls() { playTime=(TextView) findViewById(R.id.playTime); streamButton = (Button) findViewById(R.id.button_stream); streamButton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { startStreamingAudio(); }}); playButton = (ImageButton) findViewById(R.id.button_play); playButton.setEnabled(false); playButton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { if (audioStreamer.getMediaPlayer().isPlaying()) { audioStreamer.getMediaPlayer().pause(); playButton.setImageResource(R.drawable.button_play); } else { audioStreamer.getMediaPlayer().start(); audioStreamer.startPlayProgressUpdater(); playButton.setImageResource(R.drawable.button_pause); } isPlaying = !isPlaying; }}); } private void startStreamingAudio() { try { final SeekBar progressBar = (SeekBar) findViewById(R.id.progress_bar); if ( audioStreamer != null) { audioStreamer.interrupt(); } audioStreamer = new StreamingMediaPlayer(this, playButton, streamButton, progressBar,playTime); audioStreamer.startStreaming("http://192.168.64.1/xa.mp3",5208, 216); streamButton.setEnabled(false); } catch (IOException e) { Log.e(getClass().getName(), "读取音乐出错！", e); } }}

android volley简单使用 示例代码

为图片添加水印 【核心代码】 /*** 添加水印* @param imagePath      图片绝对路径* @param watermarkPath  水印图片绝对路径* @param position  水印图片位置* @return 生成水印图片的绝对路径*/public static String addWatermark(String imagePath, String watermarkPath, String position) {logger.info("为图片({})在位置{}添加水印({})", imagePath, position, watermarkPath);if (StringUtils.isNotBlank(imagePath) && StringUtils.isNotBlank(watermarkPath)) {File image = new File(imagePath);File watermark = new File(watermarkPath);Position pos = getPostion(position);if (image.isFile() && image.exists() && watermark.isFile()) {try {BufferedImage bi = ImageIO.read(image);Builder builder = Thumbnails.of(imagePath);BufferedImage watermarkImg = ImageIO.read(watermark);File newWatermark = null;// 原图的宽或高是水印图片宽或高的2倍及以上,则直接打上水印原图;否则缩略水印图片,以原图宽或高的二分之一if (bi.getWidth() / watermarkImg.getWidth()

可以完美运行，能够对mppt进行仿真，不用谢 hah
