Android 常見對話方塊

1、對話方塊通知(Dialog Notification)

當你的應用需要顯示一個進度條或需要使用者對資訊進行確認時，可以使用對話方塊來完成。

下面代碼將開啟一個的對話方塊：

    public void click1(View view) {        AlertDialog.Builder builder = new Builder(this);        builder.setTitle("工學1號館");        builder.setIcon(R.drawable.ic_launcher);        builder.setMessage("瀏覽wuyudong的部落格?");        builder.setPositiveButton("確定", new OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                Uri uri = Uri.parse("http://www.wuyudong.com/");// 開啟連結                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、建立帶單選項列表的對話方塊

    public void click2(View view) {        AlertDialog.Builder builder = new Builder(this);        builder.setTitle("單選對話方塊");        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] + "被點擊了", 0)                        .show();            }        });        builder.show();    }

3、建立帶多選項列表的對話方塊

    public void click3(View view) {        AlertDialog.Builder builder = new Builder(this);        builder.setTitle("多選對話方塊");        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、進度對話方塊(ProgressDialog)

使用代碼ProgressDialog.show(ProgressDialogActivity.this, "請稍等", "資料正在載入中...", true);建立並顯示一個進度對話方塊。
調用setProgressStyle()方法設定進度對話方塊風格。有兩種風格：
ProgressDialog.STYLE_SPINNER 旋體進度條風格 (為預設風格)
ProgressDialog.STYLE_HORIZONTAL 橫向進度條風格

    public void click4(View view) {        ProgressDialog pd = new ProgressDialog(this);        pd.setTitle("提醒");        pd.setMessage("正在載入中......");        pd.show();    }

下面的代碼實現橫向進度條風格：

    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();    }
