google提供了天气的api,以广州天气为例,地址为:
http://api.openweathermap.org/data/2.5/weather?q=guangzhou
返回的结果为:
因此,在本范例中,写一个天气查询的DEMO,用于输入地点,并查询天气情况。
效果如下:
详细步骤如下:
1、主界面布局文件
<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:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_marginTop="15dp" android:text="@string/location" android:textAppearance="?android:attr/textAppearanceMedium" /> <EditText android:id="@+id/editText1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBottom="@+id/textView1" android:layout_alignParentRight="true" android:ems="10" /> <TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@+id/textView1" android:layout_below="@+id/textView1" android:layout_marginTop="68dp" android:text="@string/country" android:textAppearance="?android:attr/textAppearanceSmall" /> <TextView android:id="@+id/textView3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/textView2" android:layout_marginTop="19dp" android:text="@string/temperature" android:textAppearance="?android:attr/textAppearanceSmall" /> <TextView android:id="@+id/textView4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@+id/textView3" android:layout_below="@+id/textView3" android:layout_marginTop="32dp" android:text="@string/humidity" android:textAppearance="?android:attr/textAppearanceSmall" /> <TextView android:id="@+id/textView5" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@+id/textView4" android:layout_below="@+id/textView4" android:layout_marginTop="21dp" android:text="@string/pressure" android:textAppearance="?android:attr/textAppearanceSmall" /> <EditText android:id="@+id/editText2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_above="@+id/textView3" android:layout_toRightOf="@+id/textView3" android:ems="10" > <requestFocus /> </EditText> <EditText android:id="@+id/editText3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBaseline="@+id/textView3" android:layout_alignBottom="@+id/textView3" android:layout_alignLeft="@+id/editText2" android:ems="10" /> <EditText android:id="@+id/editText4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_above="@+id/textView5" android:layout_alignLeft="@+id/editText1" android:ems="10" /> <EditText android:id="@+id/editText5" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBaseline="@+id/textView5" android:layout_alignBottom="@+id/textView5" android:layout_alignRight="@+id/editText4" android:ems="10" /> <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@+id/editText2" android:layout_below="@+id/editText1" android:onClick="open" android:text="@string/weather" /> </RelativeLayout>
<?xml version="1.0" encoding="utf-8"?> <resources> <string name="app_name">JSONParser</string> <string name="action_settings">Settings</string> <string name="hello_world">Hello world!</string> <string name="location">Location</string> <string name="country">Country:</string> <string name="temperature">Temperature:</string> <string name="humidity">Humidity:</string> <string name="pressure">Pressure:</string> <string name="weather">Weather</string> </resources>
