我制作了使用WebView的android web应用程序。问题是当我按下geo:或tel:链接时它停止工作。我从这里尝试了很多技巧,但不是它们的实际工作。
XML布局:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.app.MainActivity"
tools:ignore="MergeRootFrame"
android:screenOrientation="portrait">
<WebView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:id="@+id/activity_main_webview"/>
</FrameLayout>
MainActivity.java
package com.example.app;
import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.os.Build;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends ActionBarActivity {
private WebView mWebView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
mWebView.loadUrl("http://example.com");
// Force links and redirects to open in the WebView instead of in a browser
mWebView.setWebViewClient(new WebViewClient());
// Stop local links and redirects from opening in browser instead of WebView
mWebView.setWebViewClient(new MyAppWebViewClient());
mWebView = (WebView) findViewById(R.id.activity_main_webview);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.setInitialScale(1);
}
@Override
// Detect when the back button is pressed
public void onBackPressed() {
if(mWebView.canGoBack()) {
mWebView.goBack();
} else {
// Let the system handle the back button
super.onBackPressed();
}
}
/**
* A placeholder fragment containing a simple view.
*/
public static class PlaceholderFragment extends Fragment {
public PlaceholderFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
return rootView;
}
}
}
MyAppWebViewClient.java
package com.cromedia.zadarguide;
import android.content.Intent;
import android.net.Uri;
import android.webkit.WebView;
import android.webkit.WebViewClient;
/**
* Created by Ivan on 27.02.14..
*/
public class MyAppWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(Uri.parse(url).getHost().endsWith("example.com")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app" >
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.app.MainActivity"
android:configChanges="orientation"
android:screenOrientation="portrait"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
我对此很陌生,我接受了这个说明来制作应用https://developers.google.com/chrome/mobile/docs/webview/gettingstarted
那么,任何人都可以尝试填充缺少的内容,以便在按下geo:或tel:link时不会崩溃并处理geo:和tel:链接,例如chrome?
我找到了答案!!!
我在MyAppWebViewClient.java中替换了这段代码
public class MyAppWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(Uri.parse(url).getHost().endsWith("example.com")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
这一个
public class MyAppWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost() != null && Uri.parse(url).getHost().equals("domain.com"))
{
return false;
}
else {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
}
