增加游戏难度

Question

我想在我的游戏中添加一个难度，例如当我点击类别"a"时，它将显示到下一个布局，用户必须选择一个难度来玩"简单，普通或困难"。

对不起，我说错了句话

下面是我的分类:

public class CategoryActivity extends Activity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);       
        super.onCreate(savedInstanceState);
        setContentView(R.layout.category);
        Button A = (Button) findViewById(R.id.btn_a);
        Button B = (Button) findViewById(R.id.btn_b);
        Button C = (Button) findViewById(R.id.btn_c);
        Button D = (Button) findViewById(R.id.btn_d);
        Button E = (Button) findViewById(R.id.btn_e);
        Button F = (Button) findViewById(R.id.btn_f);
        Button G = (Button) findViewById(R.id.btn_g);
        Button H = (Button) findViewById(R.id.btn_h);
        Button I = (Button) findViewById(R.id.btn_i);
        Button J = (Button) findViewById(R.id.btn_j);
        A.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                startActivity(new Intent(CategoryActivity.this, DifficultyActivity.class));
            }
        });
 B.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg1) {
                startActivity(new Intent(CategoryActivity.this, DifficultyActivity.class));
                }
        });
 C.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg2) {
            startActivity(new Intent(CategoryActivity.this, DifficultyActivity.class));
        }
    });
 D.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg3) {
            startActivity(new Intent(CategoryActivity.this, DifficultyActivity.class));
        }
    });
 E.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg4) {
            startActivity(new Intent(CategoryActivity.this, DifficultyActivity.class));
        }
    });
 F.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg5) {
            startActivity(new Intent(CategoryActivity.this, DifficultyActivity.class));
        }
    });
 G.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg6) {
            startActivity(new Intent(CategoryActivity.this, DifficultyActivity.class));
        }
    });
 H.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg7) {
            startActivity(new Intent(CategoryActivity.this, DifficultyActivity.class));
        }
    });
 I.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg8) {
            startActivity(new Intent(CategoryActivity.this, DifficultyActivity.class));
        }
    });
 J.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View arg9) {
            startActivity(new Intent(CategoryActivity.this, DifficultyActivity.class));
        }
    });
    }

你应该使用单选按钮，这样用户只能选择一个选项，而不是两个或多个。

这是一个来自android开发者官方网站的例子。

public void onRadioButtonClicked(View view) {
    // Is the button now checked?
    boolean checked = ((RadioButton) view).isChecked();
    // Check which radio button was clicked
    switch(view.getId()) {
        case R.id.radio_pirates:
            if (checked)
                // Pirates are the best
            break;
        case R.id.radio_ninjas:
            if (checked)
                // Ninjas rule
            break;
    }
}
