Android 如何使开关和机箱工作？

我有一个Android游戏项目，其源代码如下：

package com.example.fun;

          public void onClick(View v) {
              if( buttonD.getId() == ((Button)v).getId() ){
                  txtD.setVisibility(View.VISIBLE);
              }
              else if( buttonO.getId() == ((Button)v).getId() ){
                  txtO.setVisibility(View.VISIBLE);
              }
              else if( buttonG.getId() == ((Button)v).getId() ){

              }

          }

};

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.dog, menu);
        return false;
    }

}

但当我运行它时，开关和案例代码不起作用。是我放错地方了还是代码错了？谢谢你的回答

您可以根据自己的要求检查以下答案

这将正常工作，我只是改变了一些 没有别的了

见下文

View.OnClickListener myOnlyhandler = new View.OnClickListener() {

      public void onClick(View v) {
          if( R.id.buttond == ((Button)v).getId() ){
              txtD.setVisibility(View.VISIBLE);
          }
          else if( buttonO.getId() == ((Button)v).getId() ){
              txtO.setVisibility(View.VISIBLE);
          }
          else if( R.id.buttono == ((Button)v).getId() ){
              txtG.setVisibility(View.VISIBLE);
              i = new Intent(DogActivity.this, HouseActivity.class);
                startActivity(i);   
          }
          else if( R.id.buttonnext == ((Button)v).getId() ){
              i = new Intent(DogActivity.this, HouseActivity.class);
                startActivity(i);   
          }
          else{
              MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.no);
                mp.start();
              life--;   
                **switch (life) {
                case 2:
                    nyaw.setVisibility(View.INVISIBLE);
                break;
                case 1:
                    nyaw2.setVisibility(View.INVISIBLE);
                break;
                case 0:
                    nyaw3.setVisibility(View.INVISIBLE);
                    i = new Intent(DogActivity.this, TamatActivity.class);
                    startActivity(i);
                break;
            }**
          }

      }
  //You can also use switch case for this.
};

在

life之后--

记录life的值并检查它是否与任何case匹配尝试向每个if/else子句和switch case添加调试语句，以查看代码是否得到执行。您可以使用Log.d（“标记”、“消息”）进行调试；试着在信息部分打印一些有用的东西，例如按钮的名称或箱子的编号。这将显示在您的LogCat控制台中。@Daniel。Logcat不用于调试（一般情况下）。顾名思义，它是用来记录日志的。请不要在Android社区继续这种疾病，那里的人们没有学会使用

调试器

，这是发现类似问题的正确方法。如果每个人都使用调试器，那么StackOverflow上90%的问题都是不必要的。“不工作”是什么意思？它什么也没告诉我们。@Raghunandan它是有效的。谢谢。。
