我需要创建3个时间选择器并将它们存储在SQLite中。但我不知道。任何建议和建议将不胜感激。
public class Main extends AppCompatActivity implements View.OnClickListener{
private TimePick tp;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tableworkdetails);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
tp = new TimePick();
start = (EditText) findViewById(R.id.editTextTI1);
end = (EditText) findViewById(R.id.editTextTO1);
start1 = (EditText) findViewById(R.id.editTextTI2);
end1 = (EditText) findViewById(R.id.editTextTO2);
start2 = (EditText) findViewById(R.id.editTextTI3);
end2 = (EditText) findViewById(R.id.editTextTO3);
editTextH1=(EditText)findViewById(R.id.editTextH1); // display total hours based on user input
start.setOnClickListener(this);
end.setOnClickListener(this);
start1.setOnClickListener(this);
end1.setOnClickListener(this);
start2.setOnClickListener(this);
end2.setOnClickListener(this);
}
public void onClick(View v) {
int id = v.getId();

} else if (id == R.id.editTextTO1) {
tp.setFlag(TimePick.FLAG_END_DATE);

}
}
