我是android的新手,我正在创建一个测试程序来测试search dialog
android。这是searchable.xml配置文件
<?xml version="1.0" encoding="utf-8"?>
<searchable
xmlns:android="http://schemas.android.com/apk/res/android"
android:label="Search"
android:hint="Type text to search">
</searchable>
这是清单文件
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="luan.com.bk"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity android:name=".SearchActivity" >
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="@xml/searchable" />
</activity>
<activity
android:name=".TestActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data
android:name="android.app.default_searchable"
android:value=".SearchActivity" />
</activity>
</application>
</manifest>
这是请求搜索的searchActivity.java
package luan.com.bk;
import android.app.Activity;
import android.os.Bundle;
public class SearchActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
}
}
这是testActivity.java初始化搜索对话框
package luan.com.bk;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
public class TestActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
但是当我在android模拟器上按搜索键按钮时,搜索栏不显示,我怎么了?请帮忙。对不起,因为我的英语不好。
