Как из класса ArrayAdapter по нажатию на кнопку перейти на другой Activity?
есть ProductAdapter. в котором надо сделать переход на MapsActivity.class. код:
class ProductAdapter extends ArrayAdapter<Product> {
private LayoutInflater inflater;
private int layout;
private ArrayList<Product> productList;
Intent intent_maps;
ProductAdapter(Context context, int resource, ArrayList<Product> products) {
super(context, resource, products);
this.productList = products;
this.layout = resource;
this.inflater = LayoutInflater.from(context);
}
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder viewHolder;
if(convertView==null){
convertView = inflater.inflate(this.layout, parent, false);
viewHolder = new ViewHolder(convertView);
convertView.setTag(viewHolder);
}
else{
viewHolder = (ViewHolder) convertView.getTag();
}
final Product product = productList.get(position);
viewHolder.nameView.setText(product.getName());
viewHolder.yearView.setText(product.getYear());
viewHolder.sizeView.setText(product.getSize());
viewHolder.removeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {//здесь идет переход
// Intent Fragment1 = new Intent(ProductAdapter.this, MainActivity.class); не работает
// startActivity(Fragment1);
/*Intent intent_list = new Intent(getContext(), MapsActivity.class);
startActivity(getContext(), intent_list);
//Intent intent = new Intent(getContext(), MapsActivity.class);
//getContext().startActivity(intent);
// productList.get(1);
/* int count = product.getCount()-1;
if(count<0) count=0;
product.setCount(count);
viewHolder.sizeView.setText(count + " " + product.getUnit());*/
}
});
viewHolder.addButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
/* int count = product.getCount()+1;
product.setCount(count);
viewHolder.yearView.setText(count + " " + product.getUnit());*/
}
});
return convertView;
}
private class ViewHolder {
final Button addButton, removeButton;
final TextView nameView, yearView,sizeView;
ViewHolder(View view){
addButton = (Button) view.findViewById(R.id.infoButton);
removeButton = (Button) view.findViewById(R.id.lookButton);
nameView = (TextView) view.findViewById(R.id.nameView);
yearView = (TextView) view.findViewById(R.id.yearView);
sizeView = (TextView) view.findViewById(R.id.sizeView);
}
}
}
есть ListActivity. который генерирует нужное количество компонентов на форме. в нем я принимаю некоторую информацию и потом строю компоненты с этой информацией. ну текст им задаю. код:
public class ListActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_activity);
//прием
Intent intent = getIntent();
Bundle args = intent.getBundleExtra("BUNDLE");
ArrayList<Object> object = (ArrayList<Object>) args.getSerializable("ARRAYLIST");
//прием
ArrayList<Product> products = new ArrayList<Product>();
int i=0;
if(products.size()==0)
while(i<17){
products.add(new Product(object.get(i+2).toString(),object.get(i+7).toString(),object.get(i+5).toString()));
i+=8;
}
/*if(products.size()==0){
products.add(new Product("Имя","год","размер"));
products.add(new Product("Имя2","год2","размер2"));
products.add(new Product("Имя3","год3","размер3"));
}*/
ListView productList = (ListView) findViewById(R.id.productList);
ProductAdapter adapter = new ProductAdapter(this, R.layout.list_item, products);
productList.setAdapter(adapter);
}
}
я так понимаю нельзя просто так взять и в
viewHolder.removeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v)
написать Intent Fragment1 = new Intent(ProductAdapter.this, MapsActivity.class); startActivity(Fragment1);
пишет - Cannot resolve constructor Intent(com.example.animation1.ProductAdapter, java.lang.Class<com.example.animation1.MapsActivity>)
код MainActivity:
public class MainActivity extends AppCompatActivity {
TextView tv;
LinearLayout lr1;
InputStream inputStream;
String[] ids;
ArrayList<String> ar = new ArrayList<String>();
List<ArrayList<String>> a = new ArrayList<>();
ArrayList<String> temp = new ArrayList<String>();
Intent intent_list,intent_list2;
Intent intent_maps;
@Override
protected void onCreate(Bundle savedInstanceState) {
int i=0;
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv=(TextView)findViewById(R.id.textView);
lr1=(LinearLayout)findViewById(R.id.linerl1);
ArrayList<Product> products = new ArrayList<Product>();
inputStream = getResources().openRawResource(R.raw.bridge_spb_rus_test);
BufferedReader reader=new BufferedReader(new InputStreamReader(inputStream, Charset.forName("windows-1251")));
try{
String csvLine;
while ((csvLine=reader.readLine())!=null){
ids=csvLine.split(";");
for (int i2=0;i2<=7;i2++) {
ar.add(ids[i2]);
a.add(ar);
}
try {
// textView.setText(ar[1]);
}catch (Exception e){
Log.e("error",e.toString());
}
}
}catch (IOException ex){
throw new RuntimeException("error IO"+ex);
}
/* if(products.size()==0){//меняю тут!!!!
i=0;
for(ArrayList obj:a){
temp = obj;
for(String job : temp){
data2.add(job);
i++;
// products.add(new Product(job,temp.get(0)));
}
}*/
if(products.size()==0){//меняю тут!!!!
for(ArrayList obj:a)
temp = obj;
intent_list = new Intent(MainActivity.this, ListActivity.class);
intent_list2 = new Intent(MainActivity.this, ProductAdapter.class);
intent_maps=new Intent(MainActivity.this, MapsActivity.class);
Bundle args = new Bundle();
args.putSerializable("ARRAYLIST",(Serializable)temp);
intent_list.putExtra("BUNDLE",args);
intent_list2.putExtra("BUNDLE",args);
intent_maps.putExtra("maps",args);
}
}
public void Onclick_menu (View v){
if (lr1.getVisibility()==View.GONE)
{
lr1.setVisibility(View.VISIBLE);
lr1.startAnimation(AnimationUtils.loadAnimation(this,R.anim.list_up));
}
else {
lr1.setVisibility(View.GONE);
lr1.startAnimation(AnimationUtils.loadAnimation(this,R.anim.list_down));
}
}
public void Onclick_maps (View v){
startActivity(intent_maps);
}
public void Onclick_list (View v){
startActivity(intent_list);
}
}
тут я переда ListActivity список. надо мне теперь этот список получить в ProductAdapter и передать в MapsActivity. только в ProductAdapter нельзя написать:
Intent intent = getIntent();
Bundle args = intent.getBundleExtra("BUNDLE");
ArrayList<Object> object = (ArrayList<Object>) args.getSerializable("ARRAYLIST");
на строку Intent intent = getIntent(); ругается. пишет Cannot resolve method 'getIntent()'.
пакеты import android.content.Intent; есть.
