所以即时制作一个Android应用程序,一旦尝试进入我的上一个活动,我的应用程序崩溃了。请检查是否有遗漏的东西。
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class Search1 extends Activity {
String searchtype="null";
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search);
Button ISBN = (Button) findViewById(R.id.ISBN);
ISBN.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
onSearchRequested();
searchtype="ISBN";
}
});
Button Title = (Button) findViewById(R.id.Title);
Title.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
onSearchRequested();
searchtype="Title";
}
//various listeners follow
});...
public class SearchResults extends ListActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search);
// Get the intent, verify the action and get the query
Intent intent = getIntent();
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
}
}
最后是两个文件的清单
<activity android:name=".SearchResults" >
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="@xml/searchable"/>
</activity>
和
<activity android:name=".Search1"
android:label="@string/app_name"
android:screenOrientation="portrait">
<meta-data android:name="android.app.default_searchable"
android:value=".SearchResults" />
</activity>
Searchresults活动仍然不完整(xml文件只包含textview)但我仍然不认为当我尝试输入活动时应用程序应该强制关闭。这段代码有问题吗?
答案 0 :(得分:0)
我经常忘记在AndroidManifest.xml中输入我的活动,你检查过这是不是问题? =)
