我有一个使用WebView的应用程序。 但我想保存网址,例如:当应用程序启动时,它会打开google.com。因此,如果我想输入内容并保存该搜索或网站,我希望它有一个按钮:“保存网站”和“加载网站”。我该如何做到尽可能简单? 到目前为止我正在使用此代码:
package com.mysoftwaremobileapps.Finnnofortablets;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;
public class finnnoActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
Button TilbakeButton;
WebView FinnWeb;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
FinnWeb = (WebView)findViewById(R.id.FinnWeb);
FinnWeb.setWebViewClient(new MyWebViewClient());
FinnWeb.getSettings().setBuiltInZoomControls(true);
FinnWeb.getSettings().setJavaScriptEnabled(true);
FinnWeb.loadUrl("http://m.finn.no");
FinnWeb.requestFocus(View.FOCUS_DOWN);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK)) {
setContentView(R.layout.main);
FinnWeb = (WebView) findViewById(R.id.FinnWeb);
FinnWeb.setWebViewClient(new MyWebViewClient());
FinnWeb.getSettings().setJavaScriptEnabled(true);
FinnWeb.getSettings().setBuiltInZoomControls(true);
FinnWeb.requestFocus(View.FOCUS_DOWN);
FinnWeb.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
@Override
public boolean onCreateOptionsMenu(Menu meny) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menubuttons, meny);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.LoggInn:
setContentView(R.layout.main);
FinnWeb = (WebView) findViewById(R.id.FinnWeb);
FinnWeb.setWebViewClient(new MyWebViewClient());
FinnWeb.getSettings().setJavaScriptEnabled(true);
FinnWeb.loadUrl("http://m.finn.no/#loginForm.html");
FinnWeb.requestFocus(View.FOCUS_DOWN);
break;
case R.id.OmUtvikler:
setContentView(R.layout.omutvikler);
TilbakeButton = (Button)findViewById(R.id.TilbakeButton);
TilbakeButton.setOnClickListener(this);
break;
case R.id.RegistrerDeg:
setContentView(R.layout.main);
FinnWeb = (WebView) findViewById(R.id.FinnWeb);
FinnWeb.setWebViewClient(new MyWebViewClient());
FinnWeb.getSettings().setJavaScriptEnabled(true);
FinnWeb.loadUrl("http://m.finn.no/#auth/registrer.html");
FinnWeb.requestFocus(View.FOCUS_DOWN);
break;
case R.id.Tilbake:
if (FinnWeb.canGoBack()) {
FinnWeb.goBack();
}
else{
}
break;
case R.id.Frem:
if (FinnWeb.canGoForward()) {
FinnWeb.goForward();
}
else{
}
break;
case R.id.ExitWithSaving:
System.exit(0);
break;
case R.id.Exit:
System.exit(0);
break;
case R.id.LastAnnonse:
break;
}
return true;
}
public void onClick(View src) {
switch(src.getId()) {
case R.id.TilbakeButton:
setContentView(R.layout.main);
FinnWeb = (WebView) findViewById(R.id.FinnWeb);
FinnWeb.setWebViewClient(new MyWebViewClient());
FinnWeb.getSettings().setJavaScriptEnabled(true);
FinnWeb.getSettings().setBuiltInZoomControls(true);
FinnWeb.requestFocus(View.FOCUS_DOWN);
break;
}
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
private class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
}
答案 0 :(得分:1)
有几种不同的方法可以做到这一点。第一种是通过已经覆盖的“shouldOverrideUrlLoading”中的钩子来记住URL。
像:
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{ view.loadUrl(url);
//save off url in instance variable
this.currentURL = url.toString();
return true;
}
其次是当用户通过以下方法点击您提到的“保存网站”按钮时,呼叫您的webView获取当前网址:
http://developer.android.com/reference/android/webkit/WebView.html#getUrl()
这些方法中的任何一种都允许您访问当前显示的URL。我希望这会有所帮助。
