如何在android studio中动态添加/删除线性布局

因此，我目前有一个android应用程序，只需按下一个按钮即可添加和删除一行线性布局。线性布局包含两个edittext和两个textview，但该行添加在列表的末尾，我想知道是否有方法添加/删除取决于所选edittext的线性布局的一行。如何在android studio中动态添加/删除线性布局

例如：我有4行线性布局，第2行中的edittext被选中，我按下add按钮，然后在第2行和第3行之间插入一行。下面是我的代码

ToggleButton timeTempToggle; 
ArrayList<EditText> dataET = new ArrayList<>(); 

Button buttonAddStep,buttonRemoveStep; 

int id=1; //the id number which indicates the number of commands that will be used 


LinearLayout mainLayout; //orientation is vertical 

    @Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.new_parameters); 
    buttonAddStep = (Button) findViewById(R.id.buttonAddStep); 
    buttonRemoveStep = (Button) findViewById(R.id.buttonRemoveStep); 
    mainLayout = (LinearLayout) findViewById(R.id.mainlayout); 




    buttonAddStep.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      if(id<8) { 
       //adds a stage to be included (limit is 8) 
       id++; 
       mainLayout.addView(linearlayout(id,"","0")); 
       //append after all lines 
      } 

     } 
    }); 

buttonRemoveStep.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      if(id>1){ // removes a step from the list of steps 
       //removes the stage from the thermal cycling procedure 
       //will not remove the first step 
       id--; 
       mainLayout.removeViewAt(id); 
       dataET.remove(dataET.size()-1); 
       dataET.remove(dataET.size()-1); 
       //remove the last value and line 
      } 
     } 
    }); 
} 
private LinearLayout linearlayout(int _intID, String et1, String et2) 
{ 
    LinearLayout LLMain=new LinearLayout(this); 
    LLMain.setId(_intID); 
     LLMain.addView(textView(_intID, String.valueOf(_intID) + " Temp (C): ")); 
     LLMain.addView(editText(_intID, et1)); 
     LLMain.addView(textView(_intID + 1, "Time(s): ")); 
     LLMain.addView(editText(_intID + 1, et2)); 


    LLMain.setOrientation(LinearLayout.HORIZONTAL); 
    return LLMain; 
} 

private EditText editText(int _intID,String preset) { 
    EditText editText = new EditText(this); 
    editText.setId(_intID); 
    editText.setInputType(InputType.TYPE_CLASS_NUMBER); 
    editText.setWidth(130); 
    editText.setText(preset); 
    dataET.add(editText); 
    return editText; 
} 


private TextView textView(int _intID,String Type) 
{ 
    TextView txtviewAll=new TextView(this); 
    txtviewAll.setId(_intID); 
    txtviewAll.setText(Type); 
    txtviewAll.setTypeface(Typeface.DEFAULT_BOLD); 
    return txtviewAll; 
}
