簡單展示一下AlertDialog對話框

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("短信");
        builder.setMessage("內容");
        builder.show();
        builder.setPositiveButton("確定", 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) {
            }
        });

• 單選對話框

final String[] arr = new String[]{
                "九江", "南昌", "贛州", "宜春", "景德鎮"
        };

        AlertDialog.Builder builder = new AlertDialog.Builder(Main3Activity.this);


        builder.setTitle("請選擇你喜歡的城市!");
        //設置條目
        builder.setSingleChoiceItems(arr, 0, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                Toast.makeText(Main3Activity.this, arr[i], Toast.LENGTH_LONG).show();

            }
        });


        builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {

            }
        });

        builder.setNeutralButton("取消", null);

        builder.create().show();
    }
