我已经创建了一个Android应用程序,它会显示一个数字选择器,这一切工作正常......但问题是设计....当我运行应用程序在姜饼数选择器看起来不错不错...... 。但,当我运行相同的东西在冰淇淋三明治和果冻豆的数量选择器的设计被更改一样,如下图所示。
谁能告诉我怎样留住了默认号码选取器的设计,是在姜饼果冻豆
当运行在冰淇淋三明治和果冻豆
当运行在姜面包
我使用的是自定义对话框中的号码选择器被放置时,code是下面给出

i've created an android application which displays a number picker, it all works fine...but the problem is with the design....when i run the application in gingerbread the number picker looks fine good....but when i run the same stuff in ice-cream sandwich and jelly bean the number picker design is been altered just like as shown below.
can anyone please tell me how to retain the default number-picker design that is in gingerbread in jelly bean
when runs in ice-cream sandwich and jelly bean
when runs in ginger-bread
i'm using a custom dialog box within which the number picker is placed, the code is as given below
import android.app.Activity;
import android.app.Dialog;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.widget.Button;
import android.widget.NumberPicker;
public class QuantityChangeDialog extends Dialog implements android.view.View.OnClickListener {
public Activity c;
public Dialog d;
public Button save, cancel;
NumberPicker np;
public QuantityChangeDialog(Activity a) {
super(a);
// TODO Auto-generated constructor stub
this.c = a;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
setContentView(R.layout.selecteditem_dialog);
save = (Button) findViewById(R.id.btn_save);
cancel = (Button) findViewById(R.id.btn_cancel);
save.setOnClickListener(this);
cancel.setOnClickListener(this);
np = (NumberPicker) findViewById(R.id.qntypicker);
np.setMaxValue(120);
np.setMinValue(1);
np.setValue(3);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_save:
c.finish();
break;
case R.id.btn_cancel:
dismiss();
break;
default:
break;
}
dismiss();
}
}
解决方案
Quoting from docs
If the current theme is derived from Theme the widget presents the current value as an editable input field with an increment button above and a decrement button below. Long pressing the buttons allows for a quick change of the current value. Tapping on the input field allows to type in a desired value.
You need to set your theme that is derieved from Theme
like fro example Theme.NoTitleBar.Fullscreen
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
<Button
android:id="@+id/button11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="Open" />
</RelativeLayout>
dialog.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:theme = "@style/cust_dialog"
android:layout_height="fill_parent" >
<NumberPicker
android:id="@+id/numberPicker1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="64dp" />
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/numberPicker1"
android:layout_marginLeft="20dp"
android:layout_marginTop="98dp"
android:layout_toRightOf="@+id/numberPicker1"
android:text="Cancel" />
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="@+id/button2"
android:layout_alignBottom="@+id/button2"
android:layout_marginRight="16dp"
android:layout_toLeftOf="@+id/numberPicker1"
android:text="Set" />
</RelativeLayout>
Then to display custom dialog
public class MainActivity extends Activity implements NumberPicker.OnValueChangeListener
{
private TextView tv;
static Dialog d ;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView) findViewById(R.id.textView1);
tv.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
tv.setTextColor(Color.RED);
}
else if (event.getAction() == MotionEvent.ACTION_UP) {
// set to normal color
tv.setTextColor(0);
}
return true;
}
});
Button b = (Button) findViewById(R.id.button11);
b.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
show();
}
});
}
@Override
public void onValueChange(NumberPicker picker, int oldVal, int newVal) {
Log.i("value is",""+newVal);
}
public void show()
{
final Dialog d=new Dialog(this,R.style.cust_dialog);
d.setTitle("NumberPicker");
d.setContentView(R.layout.dialog);
Button b1 = (Button) d.findViewById(R.id.button1);
Button b2 = (Button) d.findViewById(R.id.button2);
final NumberPicker np = (NumberPicker) d.findViewById(R.id.numberPicker1);
np.setMaxValue(100);
np.setMinValue(0);
np.setWrapSelectorWheel(false);
np.setOnValueChangedListener(this);
b1.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
tv.setText(String.valueOf(np.getValue()));
d.dismiss();
}
});
b2.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
d.dismiss();
}
});
d.show();
}
}
