Android常见对话框

1.普通对话框

    public void normalDialog(View v) {
        // 通过builder构造器
        AlertDialog.Builder builder = new Builder(this);
        builder.setTitle("警告");
        builder.setMessage("世界上最遥远的距离是——没有网络");
        builder.setPositiveButton("确定", new OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                System.out.println("点击了确定按钮");
            }
        });
        builder.setNegativeButton("取消", new OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                System.out.println("点击了取消按钮");
            }
        });
        builder.show();
    }

        builder.setTitle("请选择您喜欢的课程");
        final String[] items = { "Android", "IOS", "Java", "C", "C++", "C#" };
        // -1代表没有条目被选中
        builder.setSingleChoiceItems(items, -1, new OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // 把选中的条目取出来
                String item = items[which];
                Toast.makeText(getApplicationContext(), item, Toast.LENGTH_SHORT).show();
                // 关闭对话框
                dialog.dismiss();
            }
        });
        builder.show();
    }

        final boolean[] checkedItems = { true, false, false, false, false, true };
        builder.setMultiChoiceItems(items, checkedItems, new OnMultiChoiceClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which, boolean isChecked) {

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

            @Override
            public void onClick(DialogInterface dialog, int which) {
                String fruit = "";
                // 把选中的条目的数据取出来
                for (int i = 0; i < checkedItems.length; i++) {
                    if (checkedItems[i]) {
                        fruit += items[i] + " ";
                    }
                }
                Toast.makeText(getApplicationContext(), fruit, Toast.LENGTH_SHORT).show();

                for (int i = 1; i <= 100; i++) {
