Question

我想要的是当我选择一个日期时，它会过滤rss Feed以显示所选日期的道路工程。只是现在我开始打算带我去下一个显示所有道路工程的活动，而不是当天选择的那些。我该怎么做呢？

public class ChooseDate extends Activity {

    RelativeLayout rl;
    Button pick;
    DatePicker date;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.date_picker);

        rl = (RelativeLayout) findViewById(R.id.rl);
        pick = (Button) findViewById(R.id.button1);

        date = new DatePicker (ChooseDate.this);

        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams 
                ((int) LayoutParams.WRAP_CONTENT, (int) LayoutParams.WRAP_CONTENT);
        params.addRule(RelativeLayout.CENTER_IN_PARENT);

        date.setLayoutParams(params);

        rl.addView(date);

        pick.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            Toast.makeText(getBaseContext(), "Date is : " +
                date.getDayOfMonth() + "-"+(date.getMonth()+1) + 
                "-"+ date.getYear(), Toast.LENGTH_SHORT).show();
            startActivity(new Intent("com.mobilerwts.robert.MainActivityOther"));
        }
    });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
}

如果我理解这一点，您希望将日期从第一个活动传递到第二个活动。如果要这样做，则需要将其包含在Intent中。基本上，您必须在意图中包含数据。有关如何执行此操作，请参阅How do I pass data between Activities in Android application?。
