Android 当if语句为真时打开活动

嗨，我想在if语句实现时打开一个活动。如“如果gameStatus等于12，则打开scoreActivity”。守则：

import android.content.Intent;
import android.os.Bundle;

    public int gameScore;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.first_mode);

        gameScore = 0;
        gameStatus = 0;

        GridLayout gridLayout = (GridLayout)findViewById(R.id.grid_layout_6x4);

        int numColumns = gridLayout.getColumnCount();
        int numRow = gridLayout.getRowCount();

        numberOfElements = numColumns * numRow;

        MemoryButton[] buttons = new MemoryButton[numberOfElements];

        int[] buttonGraphics = new int[numberOfElements / 2];

        buttonGraphics[0] = R.drawable.card1;
        buttonGraphics[1] = R.drawable.card2;

            {
                MemoryButton tempButton = new MemoryButton(this, r, c, buttonGraphics[buttonGraphicLocations[r * numColumns + c]]);
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
                    tempButton.setId(View.generateViewId());
                }
                tempButton.setOnClickListener(this);
                buttons[r * numColumns + c] = tempButton;
                gridLayout.addView(tempButton);
            }
        }
    }

        }

        {
            int temp = buttonGraphicLocations[i];

            int swapIndex = rand.nextInt(16);

            buttonGraphicLocations[i] = buttonGraphicLocations[swapIndex];

            buttonGraphicLocations[swapIndex] = temp;
        }
    }

    private int buttonGraphicLocations(int i) {
        return 0;
    }

    @Override
    public void onClick(View view) {

        if(isBusy) {
            return;
        }

        MemoryButton button = (MemoryButton) view;

        if(button.isMatched) {

        }

        if(selectedButton1 == null)
        {

            selectedButton1.flip();
            return;
        }

        if(selectedButton1.getId()== button.getId())
        {
            return;
        }


        if (selectedButton1.getFrontDrawableId()== button.getFrontDrawableId())
        {
            button.flip();

            button.setMatched(true);

            if (selectedButton1 != null) {
                selectedButton1.setEnabled(false);
                System.out.println("not null");
            }
            else{
                System.out.println("null");
            }

                selectedButton2.setEnabled(false);
                System.out.println("not null");
            }
            else{
                System.out.println("null");
            }

            gameStatus = gameStatus + 1;
            gameScore = gameScore + 10;

            if (gameStatus == 12){
                Intent it = new Intent(Game6x4Activity.this, ActivityScore.class);
                startActivity(it);

" 有4种游戏模式：这是6x4游戏，我们可以找到24张牌（12张图片）

我想，你是在要求这样做。你可以通过

intent.putExtra("key",desired value);

---

如果（gameStatus==12）{Intent it=new Intent（Game6x4Activity.this，ActivityScore.class）；startActivity（it）；}我必须传递给另一个activity游戏运行良好，直到gameStatus达到12，当它发生时，游戏返回到主标题。。。

else if (gameStatus == 15){
 Intent intent = new Intent(Game6x4Activity.this, NextActivity.class);
 startActivity(intent);
}

intent.putExtra("key",desired value);
