我正在尝试获取Activity生命周期的日志,但是我遇到了一些奇怪的问题。
当我将activity的主题设置为android:theme="@style/Theme.AppCompat.Light.NoActionBar
并进入下一个activity时,onPause()
和onStop()
会被调用。
但是,当我使用android:theme="@style/AppTheme
时,onPause()
会被调用,但onStop()
不会被调用。
是否有基于Activity主题的事件?
您可以参考以下代码。
Styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="android:windowIsTranslucent">true</item>
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
Manifest.xml
<activity

android:label="@string/app_name"

android:theme="@style/AppTheme">

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".activity.TestTwoActivity"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:theme="@style/AppTheme" />
TestActivity
public class TestActivity extends Activity {
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
Logger.debug("TestActivity onCreate");
findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(TestActivity.this, TestTwoActivity.class);
startActivity(intent);
}
});
}
@Override

Logger.debug("TestActivity onStart");
super.onStart();
}
@Override

Logger.debug("TestActivity onRestart");
super.onRestart();
}
@Override

Logger.debug("TestActivity onResume");
super.onResume();
}
@Override
protected void onPause() {
Logger.debug("TestActivity onPause");
super.onPause();
}
@Override
protected void onStop() {
Logger.debug("TestActivity onStop");
super.onStop();
}
@Override

Logger.debug("TestActivity onDestroy");
super.onDestroy();
}
}
