我正在构建一个显示ListView的应用，然后在点击button后，它会更改为另一个ListView。
当我点击item上的list view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);
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.content.Intent;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.MenuItem;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.Toast;
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);
}
}
我的应用崩溃，我收到错误消息：
eglSurfaceAttrib not implemented
Failed to set EGL_SWAP_BEHAVIOR on surface 0xa6872d00, error=EGL_SUCCESS
我该如何解决这个问题？

答案 0 :(得分：0)
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：
AppcompatActivity或ActionBarActivity。Theme.Appcompat家庭。android.appcompat.v7.toolbar创建工具栏（因为在android v22中不推荐使用actionbar）。
