Android TimePicker小部件用于选择日期。它允许您按小时和分钟选择时间。您无法按秒选择时间。
android.widget.TimePicker是FrameLayout类的子类。
让我们看一个简单的android时间选择器示例。
package example.javatpoint.com.timepicker;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.TimePicker;
public class MainActivity extends AppCompatActivity {
TextView textview1;
TimePicker timepicker;
Button changetime;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textview1=(TextView)findViewById(R.id.textView1);
timepicker=(TimePicker)findViewById(R.id.timePicker);
//Uncomment the below line of code for 24 hour view
timepicker.setIs24HourView(true);
changetime=(Button)findViewById(R.id.button1);
textview1.setText(getCurrentTime());
changetime.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view) {
textview1.setText(getCurrentTime());
}
});
}
public String getCurrentTime(){
String currentTime="Current Time: "+timepicker.getCurrentHour()+":"+timepicker.getCurrentMinute();
return currentTime;
}
}
