我在我的主导航抽屉活动中实现了弹出窗口。我要的是从URL获得一个图像，设置ImageView的该图像中 activity_pop_up.xml，在我的主要活动如何从导航抽屉中的URL将图像添加到弹出窗口活动
这里显示弹出窗口是我的MainActivity：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// HERE IS POPUP WINDOW
LayoutInflater inflater = (LayoutInflater) MainActivity.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.activity_pop_up, null);
pw = new PopupWindow(layout, 600, 800, true);
findViewById(R.id.relativeLayoutZaFragment).post(new Runnable() {
public void run() {
pw.showAtLocation(findViewById(R.id.relativeLayoutZaFragment), Gravity.CENTER, 0, 0);
}
});
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
FragmentMainPage pocetnaFragment = new FragmentMainPage();
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.relativeLayoutZaFragment, pocetnaFragment, "1");
fragmentTransaction.commit();
getSupportActionBar().setCustomView(view,params);
getSupportActionBar().setDisplayShowCustomEnabled(true); //show custom title
getSupportActionBar().setDisplayShowTitleEnabled(false); //hide the default title
}
boolean doubleBackToExitPressedOnce = false;
@Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
assert drawer != null;
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
return;
}
else if (doubleBackToExitPressedOnce) {
super.onBackPressed();
return;
}
this.doubleBackToExitPressedOnce = true;
Toast.makeText(this, "Pritisnite još jednom za izlaz",
Toast.LENGTH_SHORT).show();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
doubleBackToExitPressedOnce = false;
}
}, 2000);
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.podesavanja)
{
return true;
}
if (id == R.id.galerija)
{
return true;
}
return super.onOptionsItemSelected(item);
}
@SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.pocetna)
{
FragmentMainPage fragmentMainPage = new FragmentMainPage() ;
FragmentManager manager = getSupportFragmentManager();
manager.beginTransaction().replace(R.id.relativeLayoutZaFragment
, fragmentMainPage, fragmentMainPage.getTag()).addToBackStack(null).commit();
TextView Title = (TextView) view.findViewById(R.id.actionbar_title);
Title.setText("Auto magazin");
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
activity_pop_up.xml：
