如何根據來自javascript的調用向通知欄添加通知?如何根據來自javascript的調用向通知欄添加通知?
我有這樣的:
package com.CheckInventory;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.WindowManager;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebStorage;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
@SuppressWarnings("unused")
public class CheckInventoryActivity extends Activity {
WebView webview;
String username;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
WebView webView = (WebView) findViewById(R.id.webview);
webView.setBackgroundColor(0);
webView.setBackgroundResource(R.drawable.myimage);
webView.addJavascriptInterface(new JavaScriptInterface(this), "Android");
WebSettings webSettings = webview.getSettings();
webSettings.setLoadWithOverviewMode(true);
webview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webSettings.setJavaScriptEnabled(true);
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setDatabasePath("/data/data/"+this.getPackageName()+"/databases/");
webSettings.setDomStorageEnabled(true);
webview.setWebChromeClient(new WebChromeClient());
webview.loadUrl("http://192.168.0.124/android");
webview.setWebViewClient(new HelloWebViewClient());
}
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
super.onReceivedError(view, errorCode, description, failingUrl);
webview.loadUrl("file:///android_asset/nodata.html");
Toast.makeText(getApplicationContext(),"Not online", Toast.LENGTH_LONG).show();
}
}
@Override
public boolean onKeyDown (int keyCode, KeyEvent event) {
if((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()){
//webview.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
JavascriptInterface.Java
package com.CheckInventory;
import android.widget.Toast;
import android.content.Context;
public class JavaScriptInterface {
Context mContext;
/** Instantiate the interface and set the context */
JavaScriptInterface(Context c) {
mContext = c;
}
/** Show a toast from the web page */
public void showToast(String toast) {
Toast.makeText(mContext, toast, Toast.LENGTH_LONG).show();
}
}
我的JavaScript正確地與Android應用程序,因爲我看到了土司接口,如何將通知添加到通知欄?我對android非常陌生,並且不知道如何從我在互聯網上找到的示例轉到我的應用中的有用狀態。
謝謝!
我會從這裏開始:http://developer.android.com/guide/topics/ui/notifiers/notifications.html,並將其納入'showToast()'方法。 – Eric
