以下是我对该视图的活动
public class TimesheetActivity extends AppCompatActivity {
TextView selectedTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_timming_list);
Intent data = getIntent();
String times = data.getStringExtra("Times");
int counter = 1;
counter = fillFields(R.id.sundayTimesList, times, counter);
counter = fillFields(R.id.mondayTimesList, times, counter);
counter = fillFields(R.id.tuesdayTimesList, times, counter);
counter = fillFields(R.id.wednesdayTimesList, times, counter);
counter = fillFields(R.id.thursdayTimesList, times, counter);
counter = fillFields(R.id.fridayTimesList, times, counter);
fillFields(R.id.saturdayTimesList, times, counter);
}
private int fillFields(int id, String data, int counter){
ViewGroup timeList = findViewById(id);
for(int i = 0; i < 5; i++) {
ViewGroup firstModayTimeListChild = (ViewGroup) timeList.getChildAt(i);
ViewGroup period = (ViewGroup) firstModayTimeListChild.getChildAt(1);
TextView periodFromText = (TextView) period.getChildAt(0);
TextView periodToText = (TextView) period.getChildAt(2);
periodFromText.setClickable(true);
periodFromText.setFocusableInTouchMode(false);
periodFromText.setTextSize(TypedValue.COMPLEX_UNIT_SP, 20);
periodToText.setTextSize(TypedValue.COMPLEX_UNIT_SP, 20);
periodFromText.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view){
Toast.makeText(getApplicationContext(), "WORKS!", Toast.LENGTH_SHORT).show();
setDate(view);
}
});
periodToText.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view){
setDate(view);
}
});
// Log.i("FOCUSABLE ", "" + periodFromText.isFocusable());
// Log.i("FOCUSABLE TOUCH MODE ", "" + periodFromText.isFocusableInTouchMode());
// Log.i("IS CLICKABLE ", "" + periodFromText.isClickable());
periodFromText.setText(
String.format(
data.charAt(++counter) + "" +
data.charAt(++counter) + ":" +
data.charAt(++counter) + "" +
data.charAt(++counter)
));
periodToText.setText(
String.format(
data.charAt(++counter) + "" +
data.charAt(++counter) + ":" +
data.charAt(++counter) + "" +
data.charAt(++counter)
));
}
return counter;
}
public void setDate(View view){
selectedTextView = (TextView) view;
view.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view){
showDialog(0);
}
});
}
protected Dialog onCreateDialog(int id){
Calendar now = Calendar.getInstance();
TimePickerDialog timePickerDialog = new TimePickerDialog(this, TimePickerDialog.THEME_HOLO_DARK, timePickerListener, now.get(Calendar.HOUR_OF_DAY), now.get(Calendar.MINUTE), true);
return timePickerDialog;
}
private TimePickerDialog.OnTimeSetListener timePickerListener = new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker timePicker, int hour, int minute) {
selectedTextView.setText(String.format("%02d:%02d", hour, minute));
}
};
}
所以我的问题是当我第一次触摸/点击textview时“toast”启动了datepicker没有显示，但是之后每当我触摸/点击时我都能看到datepicker？当我第一次按textview时为什么没有出现datepicker？如何使它起作用？
vikas kumar感谢帮助

原因是你第一次点击它时设置了点击监听器，因为你在setDate(View view);之后设置了它，它会监听后续的呼叫。所以你需要稍微改变一下方法。
public void setDate(View view){
selectedTextView = (TextView) view;
showDialog(0);
}
或者您也可以在onClick网站上为日期选择器执行此操作。
periodFromText.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view){
Toast.makeText(getApplicationContext(), "WORKS!", Toast.LENGTH_SHORT).show();
selectedTextView = (TextView) view;
showDialog(0);
}
});
这不要求你为同一个TextView设置两个onClickListeners。

将您的setDate()方法修改为以下
public void setDate(View view){
selectedTextView = (TextView) view;
showDialog(0);
}
