不使用瀏覽器打開網址

Question

我正在尋找一種在應用程序上而不是在瀏覽器中打開 Url 的方法。 我在這里發現了同樣的問題，有些人提到在不使用瀏覽器的情況下無法從應用程序打開 url。 任何人都可以建議或展示一種無需使用瀏覽器即可打開網址的方法。

任何幫助將不勝感激 。 提前致謝。

Answer 1

您可以使用網絡視圖在您的應用程序中打開 url。 這是關於它的官方谷歌文檔http://developer.android.com/reference/android/webkit/WebView.html

Answer 2

您可以在新活動或片段中使用 webview

如果你想要樣品然后問我

 package com.bala.computer.ojooo; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.Menu; import android.view.MenuItem; import android.view.Window; import android.webkit.WebChromeClient; import android.webkit.WebSettings; import android.webkit.WebView; import android.webkit.WebViewClient; import android.widget.ProgressBar; import com.google.android.gms.ads.AdRequest; import com.google.android.gms.ads.AdView; public class OjoooMain extends AppCompatActivity { WebView mWebView; AdView mAdView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_ojooo_main); final ProgressBar Pbar; //final TextView txtview = (TextView)findViewById(R.id.tV1); Pbar = (ProgressBar) findViewById(R.id.pB1); mAdView = (AdView) findViewById(R.id.adView); AdRequest adRequest = new AdRequest.Builder().build(); mAdView.loadAd(adRequest); getWindow().setFeatureInt(Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON); mWebView = (WebView) findViewById(R.id.ojoooview); mWebView.getSettings().setLoadWithOverviewMode(true); mWebView.getSettings().setUseWideViewPort(true); WebSettings webSettings = mWebView.getSettings(); webSettings.setJavaScriptEnabled(true); mWebView.loadUrl("http://wad.ojooo.com/register.php?ref=legendbalaraja"); mWebView.setWebViewClient(new WebViewClient() { public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } }); mWebView.setWebChromeClient(new WebChromeClient() { public void onProgressChanged(WebView view, int progress) { if (progress < 100 && Pbar.getVisibility() == ProgressBar.GONE) { Pbar.setVisibility(ProgressBar.VISIBLE); //txtview.setVisibility(View.VISIBLE); } Pbar.setProgress(progress); if (progress == 100) { Pbar.setVisibility(ProgressBar.GONE); //txtview.setVisibility(View.GONE); } } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.menu_ojooo_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here.

從您的主要活動或活動中，您有按鈕將您的意圖代碼用於打開 webview 活動並在通過意圖單擊按鈕時傳遞 url

並在 webview 活動中以字符串形式獲取它並在加載 url 中使用它

            Toast.LENGTH_LONG).show()
            }
        }
    }.start()



        }

        }

    }

    

    
 webView.loadUrl("https://www.google.co.in/")

}
