我要讓數拾取沒有對話的Android

Question

<NumberPicker 
    android:id="@+id/firstSeekBar" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_centerHorizontal="true" 
    android:layout_centerVertical="true" 
    android:background="@drawable/image3" /> 

我怎樣才能得到numberpicker的價值和動如TimePickerDialog

Answer 1

這裏是我的電話號碼選擇器，我使用的日期和時間：

import android.annotation.TargetApi; 
import android.content.Context; 
import android.os.Build; 
import android.util.AttributeSet; 
import android.widget.NumberPicker; 

@TargetApi(Build.VERSION_CODES.HONEYCOMB)//For backward-compability 
public class NumberPickerMinMax extends NumberPicker 
{ 
    public NumberPickerMinMax(Context context) 
    { 
     super(context); 
    } 

    public NumberPickerMinMax(Context context, AttributeSet attrs) 
    { 
     super(context, attrs); 
     processAttributeSet(attrs); 
    } 

    public NumberPickerMinMax(Context context, AttributeSet attrs, int defStyle) 
    { 
     super(context, attrs, defStyle); 
     processAttributeSet(attrs); 
    } 

    private void processAttributeSet(AttributeSet attrs) 
    { 
     //This method reads the parameters given in the xml file and sets the properties according to it 
     this.setMinValue(attrs.getAttributeIntValue(null, "min", 0)); 
     this.setMaxValue(attrs.getAttributeIntValue(null, "max", 0)); 
    } 
} 

現在，你需要添加4 NumberPickerMinMax的時間每個數字：HH：MM，這裏是我的佈局：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <RelativeLayout 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentRight="true" 
     android:layout_alignParentTop="true" > 

     <com.evapp.customViews.NumberPickerMinMax 
      android:id="@+id/TimePickerView_hour2" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_margin="2dp" 
      min="0" 
      max="9" 
      android:layout_toLeftOf="@+id/textView1" /> 

     <TextView 
      android:id="@+id/textView1" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_centerHorizontal="true" 
      android:layout_centerVertical="true" 
      android:text=" - " 
      android:textAppearance="?android:attr/textAppearanceLarge" /> 

     <com.evapp.customViews.NumberPickerMinMax 
      android:id="@+id/TimePickerView_hour1" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_alignParentTop="true" 
      android:layout_margin="2dp" 
      min="0" 
      max="2" 
      android:layout_toLeftOf="@+id/TimePickerView_hour2" /> 

     <com.evapp.customViews.NumberPickerMinMax 
      android:id="@+id/TimePickerView_minutes1" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_margin="2dp" 
      min="0" 
      max="5" 
      android:layout_toRightOf="@+id/textView1" /> 

     <com.evapp.customViews.NumberPickerMinMax 
      android:id="@+id/TimePickerView_minutes2" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_margin="2dp" 
      min="0" 
      max="9" 
      android:layout_toRightOf="@+id/TimePickerView_minutes1" /> 

    </RelativeLayout> 

</RelativeLayout> 

^h這是你需要的
