无法在html webview网页上启动新活动
[英]Start new activity on html webview Webpage not available
问题描述
I find this topic and i did same things on here .I click the button and,it's stay the browser.It's say " Navigation://OpenNativeScreen Webpage not available ".It's should start to activity.But it didn't.So it's not switch to activity. 
我找到了这个主题，并且在这里做了同样的事情。我单击按钮，然后一直停留在浏览器中。它说“ Navigation：// OpenNativeScreen网页不可用”。它应该开始活动。但是没有。所以不切换到活动。
public class acilisbir extends AppCompatActivity {
WebView myBrowser;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_acilisbir);
myBrowser = (WebView) findViewById(R.id.anasayfagetir);
myBrowser.setWebViewClient(new MyBrowser());
myBrowser.getSettings().setJavaScriptEnabled(true);
myBrowser.loadUrl("file:///android_asset/anasayfa.html");
}
private class MyBrowser extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equals("Navigation://OpenNativeScreen")) {
startActivity(new Intent(acilisbir.this,AnaEkran.class));
finish();
return true;
}
return false;
}
}
}
And html page.I use button and input for test but i'll use image later instead of this. 和html page。我使用按钮和输入进行测试，但是稍后我将使用图像代替它。

UPDATE FOR 2 2更新
I'add my manifest 我加上清单

<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.VIEW" />
<data android:scheme="activity_buy" />
</intent-filter>
</activity>
Use this code in activity 在活动中使用此代码
private class MyBrowser extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equalsIgnoreCase("Navigation://OpenNativeScreen")) {
startActivity(new Intent(acilisbir.this,AnaEkran.class));
finish();
return true;
}else if (url.equalsIgnoreCase("activity_buy://Buy")) {
startActivity(new Intent(acilisbir.this,Buy.class));
finish();
return true;
}
return false;
}
}
and html 和html
<INPUT TYPE="buycr" value="Buycr" onClick="window.location='activity_buy://Buy'">

I copied your code into a new project and amended slightly so that it would build. 我将您的代码复制到一个新项目中，并稍作修改以使其得以构建。 I then added a breakpoint to the string compare line and ran in debug mode. 然后，我在字符串比较行中添加了一个断点，并在调试模式下运行。 When the breakpoint is hit I could see that the url actually equaled "navigation://OpenNativeScreen" with a lowercase n. 当击中断点时，我可以看到该URL实际上等于"navigation://OpenNativeScreen"并带有小写字母n。 See screenshot below: 请参见下面的屏幕截图：
One possible solution would be using the url.equalsIgnoreCase method so that the case is ignored when compared. 一种可能的解决方案是使用url.equalsIgnoreCase方法，以便在比较时忽略大小写。 The full line would be: 全行为：
if (url.equalsIgnoreCase("Navigation://OpenNativeScreen")) {
