我对super()覆盖函数中的函数调用感到困惑.

@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
}

@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
}

是的代码的影响,之前或之后写什么super.onDestroy() 或 super.onPause()或其他超级功能在所有类型的android系统中被覆盖的方法呢？

如何从一开始的日期ParseObject的createdAt列,并将其转换为String在DD-MM-YYYY格式？

请仔细研究一下,让我知道出了什么问题.

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private ItemData[] itemsData;

    public MyAdapter(ItemData[] itemsData) {
        this.itemsData = itemsData;
    }

    public MyAdapter(String[] titles, int[] icons, String name, String email, int profile) {}

    // Create new views (invoked by the layout manager)
    @Override
    public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
        View itemLayoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.tab1list, null);
        // create ViewHolder
        ViewHolder viewHolder = new ViewHolder(itemLayoutView);
        return viewHolder;
    }

    // Replace the contents of a view (invoked by the layout manager)
    @Override
    public void onBindViewHolder(ViewHolder viewHolder, int position) { …

我正在以编程方式在表格行中创建多个按钮,但它们总是以左对齐方式结束.我怎样才能将整行排成一行？我正在尝试创建每一行:

TableRow row = new TableRow(getActivity());
TableLayout.LayoutParams params = new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.WRAP_CONTENT, Gravity.CENTER_HORIZONTAL);
row.setLayoutParams(params);

for (int j = 0; j != numButtonCols; j++) {
    Button b = new Button(getActivity());
    b.setOnClickListener(actionListener);
    row.addView(b);
    actionButtons[j][i] = b;
}

layout.addView(row);

我希望onClick()动画在按钮上.

我已经尝试过了

myButton.setBackgroundResource(0) 

和

myButton.setBackgroundColor(Color.TRANSPARENT)

但这两个都禁用了onClick()动画.
