Dialog的使用

看了SDK,写了这几个例子。

代码如下:

package com.chaowen;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.ProgressDialog;
import android.app.AlertDialog.Builder;
import android.content.Context;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

publicclass DialogActivity extends Activity {
    private Button dialog1,dialog2,dialog3,dialog4,dialog5,dialog6,dialog7;
    @Override
    publicvoid onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        dialog1 = (Button)findViewById(R.id.button01);
        dialog2 = (Button)findViewById(R.id.button02);
        dialog3 = (Button)findViewById(R.id.button03);
        dialog4 = (Button)findViewById(R.id.button04);
        dialog5 = (Button)findViewById(R.id.button05);
        dialog6 = (Button)findViewById(R.id.button06);
        dialog7 = (Button)findViewById(R.id.button07);
        
        
        dialog1.setOnClickListener(new OnClickListener() {

            @Override

                builder.setMessage("这是一个简单的对话框")
                .setCancelable(false)
                .setPositiveButton("确定", new DialogInterface.OnClickListener() {

                    @Override

                    }

                    }
                });
                AlertDialog alert=builder.create();
                alert.show();
            }
        });


        dialog2.setOnClickListener(new OnClickListener() {
