我的應用程序在初始運行時工作，但如果它在後臺留下一段時間然後由用戶重新啓動，我得到一個RuntimeException「無法啓動活動ComponentInfo ...錯誤膨脹類分段」。無法在從後臺返回後啓動活動
該活動包含一個包含ListView的片段。 ListView具有包含ImageView和兩個TextView的自定義適配器。
當應用程序在後臺運行並且使用了很多其他應用程序時，如果返回活動，則會引發錯誤，這會導致我相信它存在內存問題，因爲這僅在我的設備上不會發生。
如何讓我的應用程序避免此異常？
這裏是logcat的後，我在後臺很長一段時間後，恢復應用程序：

這裏是活動：
public class NowShowingActivity extends FragmentActivity{
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.nowshowing);
removeNotifications();
}
public void onRestart(){
super.onRestart();
}
public void onStop(){
super.onStop();
}
public void onDestroy(){
super.onDestroy();
}
public void onResume(){
super.onResume();
removeNotifications();
}
private void removeNotifications(){
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
mNotificationManager.cancel(1);
}
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mgoptions,menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item){
Intent myIntent;
switch(item.getItemId()){
case R.id.theater_details:
myIntent = new Intent(this, TheaterActivity.class);
this.startActivity(myIntent);
return true;
case R.id.refresh:

this.startActivity(myIntent);
return true;
case R.id.about:
myIntent = new Intent(this, AboutActivity.class);
this.startActivity(myIntent);
return true;
case R.id.settings:
myIntent = new Intent(this, SettingActivity.class);
this.startActivity(myIntent);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
這裏是nowshowing佈局：

這是正確的，非常感謝。我正在閱讀logcat不正確，認爲第一個錯誤是需要注意的錯誤。下次我會更加警惕。 –
