思路：全代码实现：

1.代码创建TextView实例
2.构造布局
3.设置TextView实例参数信息
4.编辑布局环境
5.设置点击事件监听器，添加点击事件

public class MainActivity extends AppCompatActivity {
    public TextView text1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);
        FrameLayout frameLayout = new FrameLayout(this);
        frameLayout.setBackgroundResource(R.mipmap.bg);
        setContentView(frameLayout);
        text1 = new TextView(this);
        text1.setText("开始游戏");
        text1.setTextSize(TypedValue.COMPLEX_UNIT_SP,25);
        text1.setTextColor(Color.rgb(0,85,150));
        FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
                ViewGroup.LayoutParams.WRAP_CONTENT);
        params.gravity = Gravity.CENTER;
        text1.setLayoutParams(params);
        frameLayout.addView(text1);
        text1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                new AlertDialog.Builder(MainActivity.this).setTitle("系统提示")
                        .setMessage("游戏有风险，谨慎入内，真的要进入吗？").setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        Log.i("桌面台球","进入游戏");

                    }
                }).setNegativeButton("退出",
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialogInterface, int i) {
                                Log.i("桌面台球","退出游戏");
                                finish();
                            }
                        }).show();
            }
        });


    }
}
