都市が配列されたスピナーがあります。各都市には独自の URL があります。スピナーから値を渡して、それぞれの URL を Web ビューで実行するにはどうすればよいですか? 以下は私のコードです：
MainActivity.java:
public class MainActivity extends Activity {
private Spinner spinner1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListenerOnButton();
addListenerOnSpinnerItemSelection();
}
public void addListenerOnSpinnerItemSelection() {
spinner1 = (Spinner) findViewById(R.id.spinner1);
spinner1.setOnItemSelectedListener(new CustomOnItemSelectedListener());
}
// Get selected drop down list value
public void addListenerOnButton() {
spinner1 = (Spinner) findViewById(R.id.spinner1);
final Context context = this;
Button bcitysearch = (Button) findViewById(R.id.citysearch);
bcitysearch.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Toast.makeText(MainActivity.this,
"OnClickListener : " +
"\nSpinner 1 : "+String.valueOf(spinner1.getSelectedItem()),
Toast.LENGTH_SHORT).show();
Intent intent = new Intent(context, CitySearch.class);
startActivity(intent);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
CustomOnItemSelectedListener.java:
public class CustomOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) {
Toast.makeText(parent.getContext(),
"OnItemSelectedListener : " + parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_SHORT).show();
}
public void onNothingSelected(AdapterView<?> arg0) {
}
}
CitySearch.java:
@SuppressLint("SetJavaScriptEnabled")
public class CitySearch extends Activity{
private WebView webview;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
Uri uri = Uri.parse("http://something.com/firstcity/index.html");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
//How would I parse a different url based on the selection from the spinner?
startActivity(intent);
//Initialize the WebView object with data from the 'webview.xml' file
webview = (WebView) findViewById(R.id.citywebview);
//Enable JavaScript
webview.getSettings().setJavaScriptEnabled(true);
//Set the user agent
webview.getSettings().setUserAgentString("AndroidWebView");
//Clear the cache
webview.clearCache(true);
final Activity activity = this;
webview.setWebChromeClient(new WebChromeClient(){
public void onProgressChanged(WebView view, int progress) {
//Activities and WebViews measure progress with different scales
//The progress meter will automatically disappear when we reach 100%
activity.setProgress(progress * 1000);
}
});
webview.setWebViewClient(new WebViewClient(){
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
});
webview.loadUrl("http://something.com/firstcity/index.html");
//How do I load another city from the array that has a different URL based on spinner selection?
}
}
