android中横竖屏切换和页面切换时activity生命周期的变化的测试方法以及结果

横竖屏切换时：

MainActivityonCreate
MainActivityonStart
MainActivityonResume
MainActivityonPause
MainActivityonStop
MainActivityonDestroy
MainActivityonCreate
MainActivityonStart
MainActivityonResume
MainActivityonPause
MainActivityonStop
MainActivityonDestroy
MainActivityonCreate
MainActivityonStart
MainActivityonResume

页面切换时：

MainActivityonCreate
MainActivityonStart
MainActivityonResume
MainActivityonPause
SecondActivityonCreate
SecondActivityonStart
SecondActivityonResume
MainActivityonStop
SecondActivityonPause
MainActivityonRestart
MainActivityonStart
MainActivityonResume
SecondActivityonStop
SecondActivityonDestroy

MainActivity中的代码如下，

public class MainActivity extends Activity {

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       Log.i("mtag", "MainActivity" + "onCreate");
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
   }
   public void click(View v){
       startActivity(new Intent(MainActivity.this,SecondActivity.class));
   }
   @Override
   protected void onStart() {
       Log.i("mtag", "MainActivity" + "onStart");
       super.onStart();
   }
   @Override
   protected void onRestart() {
       Log.i("mtag", "MainActivity" + "onRestart");
       super.onRestart();
   }
   @Override
   protected void onResume() {
       Log.i("mtag", "MainActivity" + "onResume");
       super.onResume();
   }
   @Override
   protected void onPause() {
       Log.i("mtag", "MainActivity" + "onPause");
       super.onPause();
   }

   @Override
   protected void onStop() {
       Log.i("mtag", "MainActivity" + "onStop");
       super.onStop();
   }
   @Override
   protected void onDestroy() {
       Log.i("mtag", "MainActivity" + "onDestroy");
       super.onDestroy();
   }

}

SecondActivity中的代码如下

public class SecondActivity extends Activity {

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       Log.i("mtag", "SecondActivity" + "onCreate");
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_second);
   }

   @Override
   protected void onStart() {
       Log.i("mtag", "SecondActivity" + "onStart");
       super.onStart();
   }
   @Override
   protected void onRestart() {
       Log.i("mtag", "SecondActivity" + "onRestart");
       super.onRestart();
   }
   @Override
   protected void onResume() {
       Log.i("mtag", "SecondActivity" + "onResume");
       super.onResume();
   }
   @Override
   protected void onPause() {
       Log.i("mtag", "SecondActivity" + "onPause");
       super.onPause();
   }

   @Override
   protected void onStop() {
       Log.i("mtag", "SecondActivity" + "onStop");
       super.onStop();
   }
   @Override
   protected void onDestroy() {
       Log.i("mtag", "SecondActivity" + "onDestroy");
       super.onDestroy();
   }
}
