当我使用setHomeButton（true）返回父级时，应用程序崩溃

I'm building an app that shows a ListView then after clicking a button it changes to another ListView.

我正在构建一个显示ListView的应用程序,然后单击一个按钮后,它将更改为另一个ListView。

When I click an item on the list view I use setHomeButtonEnabled to go to the parent Sctivity:

当我单击列表视图中的项目时,我使用setHomeButtonEnabled转到父Sctivity:

       // Here i create a homebutton
        // a homebutton that is standard in andorid
        // The homebutton goes too parent_activity and
        // in the manifest i defined parent_activity as main activity

        getSupportActionBar().setHomeButtonEnabled(true);

This works but when I use this method after I have gone back to the parent activity:

这有效,但是当我回到父活动后使用此方法时:

package com.wordpress.elektroniknu.elektroniknu;

import android.support.v7.app.ActionBarActivity;

public class ProductActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_product);

        Intent intent = this.getIntent();           //Create new Intent for receiving category
        Category category = (Category) intent.getSerializableExtra("Category");     //receive category

        new setAdapter().execute(category);         //execute new Thread for the ListView in Category
        if(category.getProductList().size() == 0)
        {
            Toast.makeText(getBaseContext(), "inga erbjudanden", Toast.LENGTH_SHORT).show();

        }

        // Here i create a homebutton
        // a homebutton that is standard in andorid
        // The homebutton goes too parent_activity and
        // in the manifest i defined parent_activity as main activity

        getSupportActionBar().setHomeButtonEnabled(true);





        getSupportActionBar().setTitle(category.getCategoryName());



    }


    //DEFINE THE THREAD
    public class setAdapter extends AsyncTask<Category, Void, String> {

        @Override
        protected String doInBackground(Category... category) {
            ListAdapter theAdapter = new productsAdapter(ProductActivity.this, category[0].getProductArray());  //Get all products in Category
            ListView theListView = (ListView) findViewById(R.id.ProductListView);
            theListView.setAdapter(theAdapter);
            return(category[0].getCategoryName());
        }

        @Override
        protected void onPostExecute(String string) {
            //Toast when thread is executed
            Toast.makeText(getBaseContext(), string, Toast.LENGTH_LONG).show();
        }
    }
  /*  @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_product, menu);
        return true;
    }*/

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

My app crashes and I get the error messages:

我的应用程序崩溃,我收到错误消息:

eglSurfaceAttrib not implemented     
Failed to set EGL_SWAP_BEHAVIOR on surface 0xa6872d00, error=EGL_SUCCESS

How can I fix this ?

我怎样才能解决这个问题 ?

Your code isn't enough to help and your logcat is hard to resolve your problem. But i think you must check some conditions below:

您的代码不足以帮助您的logcat很难解决您的问题。但我认为你必须检查下面的一些条件:

You should be used Activity extends from AppcompatActivity or ActionBarActivity.

您应该使用AppcompatActivity或ActionBarActivity中的Activity扩展。

Your Sub Activity must be used Theme.Appcompat family.

您的Sub Activity必须使用Theme.Appcompat系列。

Recheck your toolbar (actionbar). if it's null, please initialize it (Use android.appcompat.v7.toolbar for create your toolbar (because actionbar is deprecated in android v22) .

重新检查工具栏(操作栏)。如果它为null,请初始化它(使用android.appcompat.v7.toolbar创建工具栏(因为在android v22中不推荐使用actionbar)。
