在activity中的代码：
public class MainActivity extends Activity implements OnClickListener {
private Button btn_ok;
private Button btn_list;
private Button btn_myDialog;
private Button btn_progress;

@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    btn_ok = (Button) findViewById(R.id.btn_ok);    btn_list = (Button) findViewById(R.id.btn_list);    btn_myDialog=(Button) findViewById(R.id.btn_myDialog);    btn_progress=(Button) findViewById(R.id.btn_progress);    btn_ok.setOnClickListener(this);    btn_list.setOnClickListener(this);    btn_myDialog.setOnClickListener(this);    btn_progress.setOnClickListener(this);}@Overridepublic void onClick(View v) {    // TODO Auto-generated method stub    switch (v.getId()) {    //系统的对话框；    case R.id.btn_ok:        AlertDialog.Builder builder = new AlertDialog.Builder(this);        builder.setTitle("标题");        builder.setMessage("提示的内容");        builder.setIcon(R.drawable.ic_launcher);        builder.setPositiveButton("确定",                new DialogInterface.OnClickListener() {                    @Override                    public void onClick(DialogInterface arg0, int arg1) {                        // TODO Auto-generated method stub                    }                });        builder.setNegativeButton("取消",                new DialogInterface.OnClickListener() {                    @Override                    public void onClick(DialogInterface arg0, int arg1) {                        // TODO Auto-generated method stub                    }                });        builder.create().show();        break;    //系统列表框；    case R.id.btn_list:        AlertDialog.Builder builder2 = new AlertDialog.Builder(                MainActivity.this);        builder2.setTitle("选择");        builder2.setIcon(R.drawable.ic_launcher);        String items[] = { "拍照", "图片库" };        builder2.setItems(items, new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface arg0, int which) {                // TODO Auto-generated method stub                switch (which) {                case 0:                    Toast.makeText(MainActivity.this, "拍照", 0).show();                    break;                case 1:                    Toast.makeText(MainActivity.this, "图片库 ", 0).show();                    break;                }            }        });        builder2.show();        break;        //自定义封装对话框；    case R.id.btn_myDialog:        final Dialog_ask dialog = new Dialog_ask(MainActivity.this,                "对话框的标题", "提示的内容");        dialog.show();        dialog.setCanel("取消", new View.OnClickListener() {            @Override            public void onClick(View v) {                Toast.makeText(MainActivity.this, "取消", Toast.LENGTH_SHORT)                        .show();                dialog.dismiss();            }        });        dialog.setOk("确定", new View.OnClickListener() {            @Override            public void onClick(View v) {                Toast.makeText(MainActivity.this, "确定", Toast.LENGTH_SHORT)                        .show();                dialog.dismiss();            }        });        break;        //自定义正在加载中进度条;    case R.id.btn_progress:        LoadingDialog load_dialog=new LoadingDialog(this);        load_dialog.showDialog();        break;    }}

}

封装的Dialog_adk代码：

public class Dialog_ask {    Context context;    android.app.AlertDialog dialog;    TextView tv_title;    TextView tv_con;    LinearLayout buttonLayout;    Button btn_ok;    Button btn_canel;    /** * @param context * @param title 设置对话框的标题 * @param con 设置对话框的内容 */    public Dialog_ask(final Context context, String title, String con) {        // TODO Auto-generated constructor stub        this.context = context;        dialog = new android.app.AlertDialog.Builder(context).create();        View view = LayoutInflater.from(context).inflate(R.layout.dialog_ask, null);        dialog.setView(view);        //在这可以设置dialog的一些属性；        btn_ok = (Button) view.findViewById(R.id.btn_ok);        btn_canel = (Button) view.findViewById(R.id.btn_cancel);        tv_title = (TextView) view.findViewById(R.id.tv_title);        tv_con = (TextView) view.findViewById(R.id.tv_con);        tv_title.setText(title);        tv_con.setText(con);    }    public void show() {        dialog.show();    }    //确定    public void setOk(String s, final View.OnClickListener listener) {        btn_ok.setText(s);        btn_ok.setOnClickListener(listener);    }    //取消    public void setCanel(String s, final View.OnClickListener listener) {        btn_canel.setText(s);        btn_canel.setOnClickListener(listener);        // dismiss();    }    public void dismiss() {        if (dialog != null && dialog.isShowing()) {            dialog.dismiss();        }    }}

封装的Progress加载中的代码：
public class LoadingDialog {
private Context context;
private ImageView imageView;
private Dialog dialog;

public LoadingDialog(Context context) {    this.context = context;    dialog = new Dialog(context, R.style.dialog_style);    View view = LayoutInflater.from(context).inflate(R.layout.loading_dialog, null);    imageView= (ImageView) view.findViewById(R.id.img);    Animation animation= AnimationUtils.loadAnimation(            context, R.anim.load_animation);    // 使用ImageView显示动画    imageView.startAnimation(animation);    dialog.setCancelable(false);    dialog.setContentView(view);}public void showDialog() {    dialog.show();}public void dismissDialog() {    if (dialog != null && dialog.isShowing()) {        dialog.dismiss();    }}

}
