從其他活動（Android）啓動社交媒體應用或瀏覽器

Question

當前用戶單擊該按鈕時，他們將直接啓動Facebook和Twitter應用。不過，我想讓用戶能夠選擇使用瀏覽器或應用程序來查看配置文件。 另一個問題是我無法找到Instagram協議來啓動應用程序來查看配置文件，我只能在網頁上查看。任何人有想法？

 btnFb.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      String uri = "fb://page/80829078894"; 
      Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri)); 
      startActivity(intent); 

     } 
    }); 

    btnTwitter.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      String uri = "twitter://user?user_id=87114940"; 
      Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri)); 
      startActivity(intent); 

     } 
    }); 

    btnInstagram.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      String uri = "http://instagram.com/plaza_semanggi"; 
      Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri)); 
      startActivity(intent); 

     } 
    }); 

Answer 1

你的代碼更改爲以下

btnFb.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      openFacebookIntent(ActivityMain.this, "80829078894"); 


     } 
    }); 

    btnTwitter.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      openTwiterIntent(ActivityMain.this, "87114940"); 

     } 
    }); 

    btnInstagram.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      openInstagramIntent(ActivityMain.this, "plaza_semanggi"); 

     } 
    }); 

並有以下方法。

public static void openFacebookIntent(Context context, String facebookID) { 

    Intent intent; 

    try { 
     context.getPackageManager().getPackageInfo("com.facebook.katana", 0); 
     intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/facebookID")); 
    } catch (Exception e) { 
     intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/facebookID")); 
    } 

    context.startActivity(intent); 
} 

public static void openTwiterIntent(Context context, String twitterID) { 

    Intent intent; 

    try { 
     context.getPackageManager().getPackageInfo("com.twitter.android", 0); 
     intent = new Intent(Intent.ACTION_VIEW, Uri.parse("twitter://user?user_id=twitterID")); 
    } catch (Exception e) { 
     intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://twitter.com/twitterID")); 
    } 

    context.startActivity(intent); 
} 

public static void openInstagramIntent(Context context, String instagramID) { 

    Uri uri = Uri.parse("http://instagram.com/_u/instagramID"); 
    Intent intent = new Intent(Intent.ACTION_VIEW, uri); 

    intent.setPackage("com.instagram.android"); 

    try { 
     context.startActivity(intent); 
    } catch (ActivityNotFoundException e) { 
     context.startActivity(new Intent(Intent.ACTION_VIEW, 
       Uri.parse("http://instagram.com/instagramID"))); 
    } 
} 

檢查Facebook是否已安裝。

private boolean isAppInstalled(String uri) 
{ 
    PackageManager pm = getPackageManager(); 
    boolean app_installed = false; 
    try 
    { 
     pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES); 
     app_installed = true; 
    } 
    catch (PackageManager.NameNotFoundException e) 
    { 
     app_installed = false; 
    } 
    return app_installed ; 
} 

boolean appInstalled = isAppInstalled("com.facebook.katana");
