【问题描述】:
我已经制作了一个 WebView 应用程序,并且可以在上面进行深度链接。每当有人单击指向我的网站的链接(在任何其他应用程序上)时,我的应用程序就会打开,但是会加载主页而不是单击的 URL。我希望在点击链接而不是主页时打开我网站的确切 URL。
MainActivity.java

public class MainActivity extends AppCompatActivity {
private WebView YoWeb;
private ShareActionProvider mShareActionProvider;
SwipeRefreshLayout swipe;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
YoWeb = (WebView)findViewById(R.id.webview); // Move your declaration up here
swipe = (SwipeRefreshLayout) findViewById(R.id.swiperefresh);
swipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
LoadWeb(YoWeb.getUrl()); // Pass in the current url to refresh
}
});
LoadWeb("https://www.yoalfaaz.com"); // load the home page only once
}
public void LoadWeb(String url) // Pass in URL you want to load
{
WebSettings webSettings = YoWeb.getSettings();
webSettings.setJavaScriptEnabled(true);
YoWeb.loadUrl(url); // Load the URL passed into the method
swipe.setRefreshing(true);
YoWeb.setWebViewClient(new WebViewClient() {
//onPageFinished Method
public void onPageFinished(WebView view, String url) {
//Hide the SwipeRefreshLayout
swipe.setRefreshing(false);
}
});
}
@Override
public void onBackPressed() {
if (YoWeb.canGoBack()) {
YoWeb.goBack();
} else {
super.onBackPressed();
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
switch (item.getItemId()) {
case R.id.action_settings:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate menu resource file.
getMenuInflater().inflate(R.menu.menu_main, menu);
// Locate MenuItem with ShareActionProvider
MenuItem item = menu.findItem(R.id.menu_item_share);
// Fetch and store ShareActionProvider
mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item);
// Return true to display menu
return true;
}
// Call to update the share intent
private void setShareIntent(Intent shareIntent) {
if (mShareActionProvider != null) {
mShareActionProvider.setShareIntent(shareIntent);
}
}
//private Intent setShareIntent() {
// Intent shareIntent = new Intent();
// shareIntent.setAction(Intent.ACTION_SEND);
// shareIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
// shareIntent.setType("text/plain");
// startActivity(shareIntent);
// return shareIntent;
//}
}

如何使它与大多数其他应用程序一起工作?就像我们点击 WhatsApp 中的 YouTube 链接一样,该特定视频会在 YouTube 应用而不是 YouTube 主页中打开。
【问题讨论】:
-
LoadWeb("https://www.yoalfaaz.com"); // load the home page only once。嗯,打开你的主页不是吗? -
@greenapps 是的,它会打开我的主页。这是因为每次我在我网站的任何网页上滑动刷新时,我都会回到首页。
-
Whenever someone clicks a link to my website (on any other app)哪个应用程序?你的意思是一些浏览器应用程序? -
是的,那是您的主页网址。所以把点击的 url 放到那个页面上。
-
@greenapps “哪个应用程序?”具体来说,我的意思是说WhatsApp。如果我在 WhatsApp 上点击我网站的链接,它会打开我的网站,但不会打开确切的 URL。
