public class EngineerJspActivity extends Activity { private static String Tag = "EngineerJspActivity"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Log.d(Tag, "onCreate()"); setContentView(R.layout.activity_main); } @Override protected void onStart() { super.onStart(); Log.d(Tag, "onStart()"); } @Override protected void onResume() { super.onResume(); Log.d(Tag, "onResume()"); } @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); Log.d(Tag, "onSaveInstanceState()"); } @Override protected void onPause() { super.onPause(); Log.d(Tag, "onPause()"); } @Override protected void onStop() { super.onStop(); Log.d(Tag, "onStop()"); } @Override protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); Log.d(Tag, "onRestoreInstanceState()"); } @Override protected void onDestroy() { super.onDestroy(); Log.d(Tag, "onDestroy()"); } } ②运行Activity(没有切换屏幕的正常情况下启动Activity),得到如下结果:
③切换成横屏时的Activity生命周期:
④换回竖屏的Activity生命周期:
⑤给清单文件加上android:configChanges="orientation"属性,重新启动Activity,没有切换屏幕时(正常启动)的生命周期:
⑥加上android:configChanges="orientation"属性,切换成横屏,Activity的生命周期:
⑦加上android:configChanges="orientation"属性,换回竖屏,Activity的生命周期:
⑧加上android:configChanges="orientation"keyboardHidden"属性,正常启动Activity的生命周期(未切屏幕):
⑨加上android:configChanges="orientation"keyboardHidden"属性,正常启动Activity的生命周期(切成横屏):
⑩加上android:configChanges="orientation"keyboardHidden"属性,正常启动Activity的生命周期(换回竖屏):
执行Home键之后的生命周期:
