我一直在尝试自定义切换按钮外观,但没有成功.这是我希望它看起来像:

有人可以给我一个教程吗？

我需要对话框来填充屏幕,除了顶部和底部的一些空间.我正在寻找一个解决方案,但找不到一个可能是因为我正在宣布它onClickListener.有人可以给一个解决方案吗？

活动代码:

sort.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                AlertDialog.Builder sort = new AlertDialog.Builder(HomeScreen.this);
                // Get the layout inflater
                LayoutInflater inflater = HomeScreen.this.getLayoutInflater();
                View sortView = inflater.inflate(R.layout.sort_layout, null);
                sort.setView(sortView);
                sort.create().show();
            }
        });

XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_marginBottom="50dp"
    android:layout_marginTop="50dp"
    android:background="@color/white"
    android:orientation="vertical" android:layout_gravity="center">
    + some more stuff here I dont think it's relevant
</LinearLayout>

我需要为我的单选按钮创建2个环形状:

1. 白色圆圈
2. 白色圆圈与另一个圆圈内有不同的颜色

我不知道如何做到这一点.到目前为止我尝试了什么:

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

    <item android:state_checked="false"><shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="ring">
            <android:solid android:color="@color/white" />

            <android:size android:height="10dp" android:width="10dp" />

            <corners android:radius="10dp" />
        </shape></item>

</selector>

<RadioButton
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:button="@drawable/radio_shape_unchecked"
                        android:checked="false"
                        android:text="Persoana fizica" />

我正在使用模型优先方法创建一个新数据库,我想在类型的表中添加一列,System.Drawing.Color但我在属性列表中没有这个选项.

有没有办法比使用更多的数据类型？

我正在为城市制作一个可扩展的列表视图,但它不会扩展.我有另外一个几乎完全像这个,但这个不会扩大,我花了很多时间试图看到什么是错的,不能再浪费,有人可以指出问题吗？

我也调用了expandGroup(0),但它仍然没有扩展(好像没有什么可扩展的).

XML

<ExpandableListView
                        android:id="@+id/judet"
                        android:layout_width="fill_parent"
                        android:layout_height="wrap_content"
                        android:layout_margin="10dp"
                        android:choiceMode="singleChoice"
                        android:groupIndicator="@null"
                        android:smoothScrollbar="true" >
                    </ExpandableListView>

在我的主要班级

final AdapterJudet adapterJudet = new AdapterJudet(getApplicationContext());
ExpandableListView judet = (ExpandableListView) findViewById(R.id.judet);
judet.setAdapter(adapterJudet);
judet.setOnChildClickListener(new OnChildClickListener() {
            @Override
            public boolean onChildClick(ExpandableListView parent, View v,
                    int groupPosition, int childPosition, long id) {

                AdapterJudet.selected = AdapterJudet.judete[childPosition];
                judet.collapseGroup(0);
                return false;
            }
        });
