片段不被替換gridview項目點擊android

我想替換或調用片段GridView項目點擊，但當我打電話給我的片段時，GridView也是可見的，我的片段也是可見的。我需要隱藏GridView並顯示我的片段。請幫我這個。 onItemClick的GridView我想打開我的片段。我已經使用了下面的代碼。片段不被替換gridview項目點擊android

這裏是我的代碼

可以請您分享xml佈局的activity_main嗎？ –

將你的片段背景設置爲白色 –

try this   

switch (position) { 
      case 0: Information aa = new Information(); 
        FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
     fragmentTransaction.replace(R.id.frame,aa); 
     fragmentTransaction.commit(); 
     grid.setVisibility(View.GONE); 
         }

你問題出在你的碎片的background。由於您可能沒有爲該片段定義任何背景，因此它變得透明，因此兩個視圖都可見（您的GridView和片段）。

在您的片段XML的根佈局定義，例如：

android:background="@color/white"

之後，你會發現，從View片段（GridView控件）下面的單擊事件也被稱爲即使是不可見，所以在相同的佈局中，您在其中定義了整個片段的背景，還要添加：

android:clickable="true"
