プロセス：com.example.tiago.alsrm_android、PID：23337 java.lang.IllegalStateException：すでに指定された子が親を持っています。子の親で最初にremoveView（）を呼び出す必要があります。 android.view.ViewGroup.addView（viewGroup.java：3782）の は、android.view.ViewGroup.addView（ViewGroup.java：3637）の と とandroid.view.ViewGroup.addView（ViewGroup.java:3582）の にあります。 com.example.tiago.alsrm_android.Fragment.EDA_Fragment.onConfigurationChangedでandroid.view.ViewGroup.addView（ViewGroup.java:3558） （EDA_Fragment.java:174）

EDA_Fragmentフラグメントを拡張

------最初--------

------ AndroidManifest

android:name=".Activity.EDA_Activity" 
android:configChanges="orientation" 

でこれを追加する第二--------- -

in layout PORTRAIT add this -> android:orientation="vertical" 

    in layout LANDSCAPE add this -> android:orientation="horizontal" 

--------第三-----------

public void onConfigurationChanged(Configuration newConfig) { 
    super.onConfigurationChanged(newConfig); 

    LayoutInflater inflater = LayoutInflater.from(getActivity()); 
    LinearLayout linearLayout = (LinearLayout) getView(); 
    if(linearLayout != null) 
     linearLayout.removeAllViewsInLayout(); 

    // Checks the orientation of the screen 
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) { 

     ViewGroup parentViewGroup = (ViewGroup)chart.getChart().getParent(); 
     if (parentViewGroup != null) 
      parentViewGroup.removeView(chart.getChart()); 

     fragmentRootContainer = inflater.inflate(R.layout.activity_exam, linearLayout, true); 
     LineChart lineChart = (LineChart) fragmentRootContainer.findViewById(R.id.chart); 
     lineChart.addView(chart.getChart()); 
    } 
    else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){ 

     ViewGroup parentViewGroup = (ViewGroup)chart.getChart().getParent(); 
     if (parentViewGroup != null) 
      parentViewGroup.removeView(chart.getChart()); 

     fragmentRootContainer = inflater.inflate(R.layout.activity_exam, linearLayout, true); 
     inflater.inflate(R.layout.activity_exam, linearLayout, false); 

     LineChart lineChart = (LineChart) fragmentRootContainer.findViewById(R.id.chart); 
     lineChart.addView(chart.getChart()); 
    } 
}
