Android中的各種Dialog

   下面是自己總結的Android常用的幾種Dialog：

1.AlertDialog android中功能最豐富，用途最廣的對話框。

 // 1 創建一個Builder  
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    // 2 給Builder設置屬性
    builder.setTitle("Java培訓");// 設置Dialog的標題
        builder.setMessage("訪問OSC的網頁");// 設置Dialog的信息
        builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {// 設置確定按鈕

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(getApplicationContext(), "訪問OSC的網頁", 0).show();
                    }
                });
        builder.setNeutralButton("隱藏", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
            }
        });
        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
            }
        });
    //從上我們可以看出Dialog的按鈕一般分為了三種，確定builder.setPositiveButton(),隱藏builder.setNeutralButton,取消builder.setNegativeButton
    // 3 創建Dialog
        AlertDialog dialog = builder.create();

    // 4 顯示Dialog   
    dialog.show();

2.ListDialog,設置選項的時候用如下代碼：

final String[] items = { "java", "donet", "php" };
builder.setItems(items, new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(getApplicationContext(), items[which], 0).show();
            }
        });

3.singleItemDialog，這樣子能夠讓選項以單選框的樣式呈現出來：

builder.setSingleChoiceItems(items, 2, new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(getApplicationContext(), items[which], 0).show();
            }
        });

final String[] items = { "java", "donet", "php" };
        final boolean[] checkedItems = new boolean[] { true, false, false };
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("選擇語言");
        builder.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                Toast.makeText(getApplicationContext(), items[which] + isChecked, 0).show();
            }
        });

ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);// 設置為水平進度條
        progressDialog.setTitle("正在下載。。。");
        progressDialog.setMax(100);// 設置進度條的最大值
        progressDialog.setCancelable(false);// 設置回退鍵失效

        progressDialog.setButton("取消", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
            }
        });
        progressDialog.show();
        progressDialog.setProgress(50);// 設置進度條的當前刻度
