        <item name="android:windowNoTitle">true</item>
        <item name="android:backgroundDimEnabled">true</item>
    </style>

SingleAdapter的使用可以參考我的這個(gè)列子https://github.com/liuxinggen/adapter

使用方法

      ExpertDialog dialog = new ExpertDialog(activity, position, new Callback() {
            @Override
            public void callback(int position) {
                Toast.makeText(activity, "點(diǎn)擊立即咨詢(xún)" + position, Toast.LENGTH_SHORT).show();
                intent = new Intent(activity, ExpertDetailsActivity.class);
                intent.putExtra("title", "詢(xún)問(wèn)專(zhuān)家詳情");
                startActivity(intent);
            }
        });
        dialog.setIcon("http://p2.so.qhimgs1.com/t01f3cd841f22f826d2.jpg");
        dialog.setTitle("專(zhuān)家黃", "高級(jí)工程師");
        dialog.setContent(list);
        dialog.show();
