Answer 1

public class MainActivity extends Activity { Button m_Button1,m_Button2;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        m_Button1 = (Button)findViewById(R.id.Button1);
        m_Button2 = (Button)findViewById(R.id.Button2);
        
        m_Button1.setText("开始");
        m_Button2.setText("退出");
        
        m_Button1.setWidth(150);
        m_Button2.setWidth(100);
        
        m_Button1.setTextColor(Color.GREEN);
        m_Button2.setTextColor(Color.RED);
        
        m_Button1.setTextSize(30);
        m_Button2.setTextSize(20);
        
        m_Button1.setOnClickListener(new Button.OnClickListener(){
         public void onClick(View v){
         Toast toast = Toast.makeText(MainActivity.this, "你点击了“"+m_Button1.getText()+"”按钮！", Toast.LENGTH_LONG);
         toast.setGravity(Gravity.TOP, 0, 150);
         toast.show();
         }
        });
        
        m_Button2.setOnClickListener(new Button.OnClickListener(){
         public void onClick(View v){
         MainActivity.this.finish();
         }
        });
    }    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        return true;
    }    
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                NavUtils.navigateUpFromSameTask(this);
                return true;
        }
        return super.onOptionsItemSelected(item);
    }
}就这一个class了.

Answer 2

经测试Button部分的功能正常，就是不知道你下面两个Override的是干嘛的，如果是按钮部分出错，怀疑你是在布局文件那搞错了

Answer 3

没看出啥错误，唯一的一个地方@Override
  public boolean onCreateOptionsMenu(Menu menu) {
  return true;
  }
里面怎么没有设置menu

Answer 4

终于解决了   原来是AndroidManifest.xml文件里加一个<intent-filter>就行了
