Android中制作自定义dialog对话框的实例分享

     
3.在MainActivity实现对自定义对话框的添加显示。
MainActivity.java，在进行对话框切换显示的时候，只需要设置不同的xml配置文件就行了。（注意：NoticeDialog里面的构造方法的context参数只能是XXXActivity.this，不能是通过getApplicationContext获取的context对象）

package com.zlc.dialog;
 
 
import java.util.Timer;
import java.util.TimerTask;
 
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
 
import com.zlc.dialog.NoticeDialog.NoticeDialogListener;
 
public class MainActivity extends Activity {
  private Context context;
  private NoticeDialog notiDialog;
  int count = 0;
  Handler handler;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    context = getApplicationContext();
    notiDialog = new NoticeDialog(MainActivity.this,
        R.style.NoticeDialog, new NoticeDialogListener() {
      @Override
      public void onClick(View view) {
        try {
          if(view.getId() == R.id.dialog_enter){
            notiDialog.dismiss();
            //TODO 购买
          }
          notiDialog.dismiss();
        } catch (Exception e) {
          e.printStackTrace();
        }
      }
    });
    notiDialog.setContentView(R.layout.dialog_notice_choise);
    notiDialog.show();
    Timer timer = new Timer();
    handler = new Myhandler();
     
    timer.schedule(new TimerTask() {
      @Override
      public void run() {
        // TODO Auto-generated method stub
        count = count % 4;
        notiDialog.cancel();
        handler.sendEmptyMessage(count);
        count ++;
      }
    }, 3000, 3000);
  }
  private class Myhandler extends Handler{
    @Override
    public void handleMessage(Message msg) {
      // TODO Auto-generated method stub
      switch (msg.what) {
      case 0:
        notiDialog.setContentView(R.layout.dialog_notice_ing);
        break;
      case 1:
        notiDialog.setContentView(R.layout.dialog_notice_finish);
        break;
      case 2:
        notiDialog.setContentView(R.layout.dialog_notice_choise);
        break;
      default:
        break;
      }
      notiDialog.show();
    }
  }
 
}
