SWING实现类似微信的泡泡聊天界面
?在Android中做出这样的界面很简单，一个ListView + BaseAdapter + 几张图片。那在Swing中如何来实现同样的界面呢？各位对Swing有兴趣的朋友可以想想，我这里提供一种思路： JTable + TableCellRenderer + TableModel + 几张图片。其中实现TableCellRenderer是关键。下面先上一张截图：
?下面是TableCellRenderer的实现：
package org.hjm.renderer;import java.awt.Color;import java.awt.Component;import java.util.HashMap;import java.util.Map;import javax.swing.Icon;import javax.swing.ImageIcon;import javax.swing.JLabel;import javax.swing.JPanel;import javax.swing.JTable;import javax.swing.table.TableCellRenderer;import net.miginfocom.swing.MigLayout;import org.hjm.component.NinePatchImageIcon;import org.hjm.component.RLabel;import org.hjm.component.RTextPane;import org.hjm.entity.IMMessage;/** * <code>BubbleRenderer</code> * * @author Jimmy * @since v1.0.0 (Oct 15, 2013) */public class BubbleRenderer implements TableCellRenderer {LeftViewHolder mLeftHolder = new LeftViewHolder();RightViewHolder mRightHolder = new RightViewHolder();Map<String, Integer> mCacheCount = new HashMap<String, Integer>();int iCount = 0;public BubbleRenderer() {}@Overridepublic Component getTableCellRendererComponent(JTable table, Object value,boolean isSelected, boolean hasFocus, int row, int column) {Holder holder = null;IMMessage imMsg = (IMMessage)value;String sSender = imMsg.getSender();String sMsg = imMsg.getMsg();String sTime = imMsg.getTime();Integer iDisplaySide = mCacheCount.get(sSender);if (iDisplaySide == null) {iDisplaySide = iCount++;mCacheCount.put(sSender, iDisplaySide);}if (iDisplaySide % 2 == 0) {holder = mLeftHolder;} else {holder = mRightHolder;}holder.mLblUser.setText(sSender);holder.mLblTime.setText(sTime);holder.mTxtMsg.setText(sMsg);int iHeight = holder.mTxtMsg.getPreferredSize().height + 20;iHeight = iHeight < 85 ? 85 : iHeight;System.err.println(iHeight);int iH = table.getRowHeight(row);if (iH != iHeight) {table.setRowHeight(row, iHeight);}return holder;}private class Holder extends JPanel{private static final long serialVersionUID = -2850253575244483981L;JLabel mLblUser = new JLabel();JLabel mLblTime = new JLabel();RLabel mLblHead = new RLabel();RTextPane mTxtMsg = new RTextPane();public Holder() {setBackground(Color.white);}}private class LeftViewHolder extends Holder{private static final long serialVersionUID = 1L;private final Icon mBgIconLeft= new NinePatchImageIcon(this.getClass().getResource("/resource/msg_bg2.9.png"));private final Icon mHeadLeft= new ImageIcon(this.getClass().getResource("/resource/head1.png"));public LeftViewHolder() {this.setLayout(new MigLayout("ins 0"));mTxtMsg.setBackgroundIcon(mBgIconLeft);mLblHead.setIcon(mHeadLeft);this.add(mLblTime, "wmax pref");this.add(mLblUser, "pushx,growx, wrap");this.add(mLblHead, "spanx 2,split 2,wmax pref");this.add(mTxtMsg, "growy, pushy, wmin 300px");}}private class RightViewHolder extends Holder{private static final long serialVersionUID = 1L;private final Icon mBgIconRgh = new NinePatchImageIcon(this.getClass().getResource("/resource/msg_bg1.9.png"));private final Icon mHeadRight = new ImageIcon(this.getClass().getResource("/resource/head2.png"));public RightViewHolder() {this.setLayout(new MigLayout("ins 0, rtl"));mLblHead.setIcon(mHeadRight);mTxtMsg.setBackgroundIcon(mBgIconRgh);mLblUser.setHorizontalAlignment(JLabel.RIGHT);this.add(mLblTime, "wmax pref");this.add(mLblUser, "pushx,growx, wrap");this.add(mLblHead, "spanx 2,split 2,wmax pref");this.add(mTxtMsg, "growy, pushy, wmin 300px");}}}??? 如果想要转载的朋友，请注明此地址，谢谢。 附件中提供源码下载（BlogPratice.rar）, 注意编码是UTF-8。
