这是我的InfoBookActivity.java
package thesleeplesselite.drgreenthumb;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class InfoBookActivity extends ListActivity {
// -- AUTO-GENERATED CODE --
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_infobook);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_infobook, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
// noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
// -- END OF AUTO-GENERATED CODE --
}
我想使用自定义布局来设置它，这是我的 xml 代码:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context="thesleeplesselite.drgreenthumb.InfoBookActivity"
android:background="#6E5E63"
android:id="@+id/linearLayoutVertical"
android:focusableInTouchMode="false">
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:layout_marginBottom="5dp">
<ImageView

android:layout_height="35dp"
android:id="@+id/imgIconSearch"
android:src="@drawable/icon_search"
android:contentDescription="@string/str_imgIconSearch"

android:textColor="#E8CDBC" />
</LinearLayout>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/list"

</LinearLayout>

我不明白？我想我已经将 ListView 命名为“列表”，如 xml 文件中所述。
我是 Android 方面的新手，所以也许新手友好的解释会有所帮助。谢谢。
最佳答案
关键是你的堆栈跟踪:
Your content must have a ListView whose id attribute is 'android.R.id.list'
您的 xml 布局中的 ListView 需要以下 id:
<ListView
android:id="@android:id/list"
(注意它不是@+/id)
关于java - 当扩展 ListView 的 Activity 为 'Launched' 时应用程序崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30853836/
