Activity的生命周期

创建一个APP
在“MainActivity”中

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        System.out.println("onCreate");



    }

    @Override
    protected void onStart() {
        super.onStart();
        System.out.println("onStart");
    }

    @Override
    protected void onPause() {
        super.onPause();
        System.out.println("onPause");
    }

    @Override
    protected void onResume() {
        super.onResume();
        System.out.println("onResume");
    }

    @Override
    protected void onStop() {
        super.onStop();
        System.out.println("onStop");
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        System.out.println("onDestroy");
    }

    @Override
    protected void onRestart() {
        super.onRestart();
        System.out.println("onRestart");
    }
