Android 常见对话框

1、对话框通知(Dialog Notification)

当你的应用需要显示一个进度条或需要用户对信息进行确认时，可以使用对话框来完成。

下面代码将打开一个如图所示的对话框：

    public void click1(View view) {

        AlertDialog.Builder builder = new Builder(this);

        builder.setTitle("工学1号馆");

        builder.setIcon(R.drawable.ic_launcher);

        builder.setMessage("浏览wuyudong的博客?");

        builder.setPositiveButton("确定", new OnClickListener() {

            @Override

            public void onClick(DialogInterface dialog, int which) {

                Uri uri = Uri.parse("http://www.wuyudong.com/");// 打开链接

                Intent intent = new Intent(Intent.ACTION_VIEW, uri);

                startActivity(intent);

            }

        });

        builder.setNegativeButton("取消", new OnClickListener() {

            @Override

            public void onClick(DialogInterface dialog, int which) {

                 dialog.cancel();

            }

        });

        AlertDialog dialog = builder.create();

        dialog.show();

    }

2、创建带单选项列表的对话框

    public void click2(View view) {

        AlertDialog.Builder builder = new Builder(this);

        builder.setTitle("单选对话框");

        final String[] items = new String[] { "java", ".net", "php" };

        builder.setSingleChoiceItems(items, 0, new OnClickListener() {

            @Override

            public void onClick(DialogInterface dialog, int which) {

                Toast.makeText(MainActivity.this, items[which] + "被点击了", 0)

                        .show();

            }

        });

        builder.show();

    }

3、创建带多选项列表的对话框

    public void click3(View view) {

        AlertDialog.Builder builder = new Builder(this);

        builder.setTitle("多选对话框");

        final String[] items = new String[] { "java", ".net", "php", "C++" };

        builder.setMultiChoiceItems(items, new boolean[] { true, false, false,

                true }, new OnMultiChoiceClickListener() {

            @Override

            public void onClick(DialogInterface dialog, int which,

                    boolean isChecked) {

                Toast.makeText(MainActivity.this, items[which] + isChecked, 0)

                        .show();

            }

        });

        builder.setNegativeButton("取消", new OnClickListener() {

            @Override

            public void onClick(DialogInterface dialog, int which) {

                dialog.cancel();

            }

        });

        builder.show();

    }

4、进度对话框(ProgressDialog)

使用代码ProgressDialog.show(ProgressDialogActivity.this, "请稍等", "数据正在加载中...", true);创建并显示一个进度对话框。
调用setProgressStyle()方法设置进度对话框风格。有两种风格：
ProgressDialog.STYLE_SPINNER 旋体进度条风格 (为默认风格)
ProgressDialog.STYLE_HORIZONTAL 横向进度条风格

    public void click4(View view) {

        ProgressDialog pd = new ProgressDialog(this);

        pd.setTitle("提醒");

        pd.setMessage("正在加载中......");

        pd.show();

    }

下面的代码实现横向进度条风格：

    public void click5(View view) {

        final ProgressDialog pd = new ProgressDialog(this);

        pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);

        pd.setMax(100);

        pd.show();

        new Thread() {

            public void run() {

                for (int i = 0; i < 100; i++) {

                    pd.setProgress(i);

                    try {

                        Thread.sleep(20);

                    } catch (InterruptedException e) {

                        e.printStackTrace();

                    }

                }

                pd.dismiss();

            };

        }.start();

    }
