一TextView和Button以编程方式创建并添加到预先存在的垂直布局使它看起来像的意见垂直列表。这些视图仅基于用户将数据输入到中edittext并将数据保存到中的方式创建ArrayList。

如何将onClick功能添加到以编程方式创建的“垃圾箱”按钮中，从而允许他们删除与其关联的视图。

public static ArrayList<String> deckNameArray = new ArrayList<String>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    LinearLayout mainLayout = (LinearLayout)findViewById(R.id.mainLayout);

    for(int i = 0; i < deckNameArray.size(); i++)
    {
        LinearLayout layout = new LinearLayout(this);
        if ((i % 2) == 0) {
            layout.setBackgroundColor(Color.CYAN);
        } else {
            layout.setBackgroundColor(Color.WHITE);
        }
        layout.setOrientation(LinearLayout.HORIZONTAL);
        LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        layout.setLayoutParams(layoutParams);
        layout.setPadding(10, 5, 10, 5);
        layout.setWeightSum(5);
        mainLayout.addView(layout);

        LinearLayout.LayoutParams textViewParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT, 4f);
        TextView deckName = new TextView(this);
        deckName.setText(deckNameArray.get(i));
        deckName.setTextColor(Color.BLACK);
        deckName.setTextSize(18);
        deckName.setGravity(Gravity.CENTER_VERTICAL);
        deckName.setLayoutParams(textViewParams);
        layout.addView(deckName);

        LinearLayout.LayoutParams imageButtonParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT, 1f);
        ImageButton remove = new ImageButton(this);
        remove.setImageResource(R.mipmap.trash);
        if ((i % 2) == 0) {
            remove.setBackgroundColor(Color.CYAN);
        } else {
            remove.setBackgroundColor(Color.WHITE);
        }
        remove.setLayoutParams(imageButtonParams);
        layout.addView(remove);
    }

remove.setOnClickListener(new View.OnClickListener() {
         public void onClick(View v) {
             // Perform action on click
         }
     });
