私はフラグメントの と を使用しており、タブの 1 つに、4 つのセグメント化されたコントロール ボタン (「2hrs」、「8hrs」、「24hrs」、および「1wk」というラベルが付いている) と残りを占めるフレームを含むというフラグメントを表示しactionbarsherlockます。画面の。tabhostsegmentedControlFrag
グループのボタンの 1 つsegmentedcontrolが選択されると、asyncリクエストがいくつかの重要な情報を取得します。フレームは(visualFragmentFrag)、リクエストからの重要な情報をエクストラとして含む新しいフラグメントに置き換えられます。
セグメント化されたコントロール グループの各ボタンをクリックすると、それぞれ独自のバリエーションが読み込まれますvisualTrendsFrag。まったく別のタブを選択して戻ることもでき、最後に選択したセグメント化されたコントロールに問題なくロードされます。
この問題は、次のコード行を の中に追加したときにのみ始まりonCreateViewますsegmentedControlFrag。
segmentText.check(R.id.button_one);
このコード行を追加したときの logcat の問題は、すべてコンテキストに関連する null ポインター エラーです。上記の行を省略しても機能しますが、フラグメントの管理方法もsegmentedControlFrag間違っていると思われます。
