如何在 android 中添加具有两个微调项的小部件并放入单个对话框中

Question

我正在尝试设计具有两个列表（可滚动）的确认对话框。一部分显示英尺数，另一部分显示英寸值。这应该在一个对话框中，如下图所示。对此的任何建议表示赞赏。

我通过使用以下代码实现了这个UI
mycustomwidget.xml

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">
    <TextView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="0.5"
        android:text="@string/txtHeight"
        android:id="@+id/tvHeight" />
    <EditText
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.50"
        android:id="@+id/editText_Height"
        android:hint="select Height"
        android:paddingBottom="8dp"
        android:background="@drawable/border_bottom" />
</LinearLayout>

在我的Activity中使用此代码获取对话框

editText_Height.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
    final Dialog dialog = new Dialog(ProfileInfo.this);
    dialog.setContentView(R.layout.height_picker);
    dialog.show();
    }
});

heightpicker.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="250dp"
    android:layout_height="wrap_content">
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/txtHeight"
        android:layout_marginTop="24dp"
        android:textAlignment="center"/>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:background="@drawable/border_bottom">
        <com.myapp.HelperClasses.MyNumberPicker
            android:id="@+id/footValue"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="0.5"
            android:layout_gravity="center"
            android:orientation="vertical"
            max="7"
            min="4" />
        <com.myapp.HelperClasses.MyNumberPicker
            android:id="@+id/inchValue"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="0.5"
            android:layout_gravity="center"
            android:orientation="vertical"
            max="11"
            min="0" />
    </LinearLayout>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="52dp"
        android:orientation="horizontal">
        <TextView
            android:id="@+id/textView_cancel"
            android:layout_width="0dp"
            android:layout_weight="0.5"
            android:layout_height="36dp"
            android:layout_marginTop="8dp"
            android:layout_marginLeft="24dp"
            android:text="@string/txtCancel"
            android:textAlignment="center"
            android:textColor="@color/blue"/>
        <TextView
            android:id="@+id/textView_Okay"
            android:layout_width="0dp"
            android:layout_weight="0.5"
            android:layout_height="32dp"
            android:layout_marginTop="8dp"
            android:layout_marginLeft="8dp"
            android:layout_marginRight="8dp"
            android:text="@string/txtOkay"
            android:textAlignment="center"
            android:textColor="@color/blue"/>
    </LinearLayout>
</LinearLayout>

你可以这样使用NumberPicker

<NumberPicker
        android:id="@+id/numberPicker1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"  />

Java

public class MainActivity extends Activity {

    NumberPicker np;
    TextView tv1, tv2;

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

        np = (NumberPicker) findViewById(R.id.numberPicker1);
        tv1 = (TextView) findViewById(R.id.textView2);
        tv2 = (TextView) findViewById(R.id.textView3);

        np.setMinValue(0);
        np.setMaxValue(10);
        np.setWrapSelectorWheel(false); 

        np.setOnValueChangedListener(new OnValueChangeListener() {

        @Override
        public void onValueChange(NumberPicker picker, int oldVal, int newVal) {
            // TODO Auto-generated method stub

            String Old = "Old Value : ";
            String New = "New Value : ";

            tv1.setText(Old.concat(String.valueOf(oldVal)));
            tv2.setText(New.concat(String.valueOf(newVal)));
        }
    });
    }
