打开MainActivity在其中点击按钮，进入BAactivity，然后再退出。代码如下
packagecom.example.liuping.myapplication;
importandroid.content.Intent;
importandroid.support.v7.app.AppCompatActivity;
importandroid.os.Bundle;
importandroid.util.Log;
importandroid.view.View;
public classMainActivityextendsAppCompatActivity {
private static finalStringTAG= MainActivity.class.getSimpleName();
@Override
protected voidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.e(TAG,"onCreate---"+TAG);
}
@Override
protected voidonStart() {
super.onStart();
Log.e(TAG,"onStart---"+TAG);
}
@Override
protected voidonResume() {
super.onResume();
Log.e(TAG,"onResume---"+TAG);
}
@Override
protected voidonRestart() {
super.onRestart();
Log.e(TAG,"onRestart---"+TAG);
}
@Override
protected voidonRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
Log.e(TAG,"onRestoreInstanceState---"+TAG);
}
@Override
protected voidonPause() {
super.onPause();
Log.e(TAG,"onPause---"+TAG);
}
@Override
protected voidonStop() {
super.onStop();
Log.e(TAG,"onStop---"+TAG);
}
@Override
protected voidonDestroy() {
super.onDestroy();
Log.e(TAG,"onDestroy---"+TAG);
}
public voidgoB(View view) {
Intent intent=newIntent(this,BActivity.class);
startActivity(intent);
}
}
结果如下：
