我在1周后遇到此错误。一旦我将空listview放入linearlayout，我就会出现内存不足错误。 xml的结构是：
TabHost - ＆gt;的ListView
请帮我找出让我收到错误的原因。
编辑：tabhost在没有ListView的情况下工作。我意识到了;即使我只使用ListView创建一个完整的新布局，它也失败了。
这是我的代码：
public class FriendsAndGroups extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.friendsandgroups);
setUpLayout();
}
private void setUpLayout() {
final TabHost tabHost = (TabHost) findViewById(R.id.tabHostFriendsAndGroups);
tabHost.setup();
final TabWidget tabWidget = tabHost.getTabWidget();
final FrameLayout tabContent = tabHost.getTabContentView();
// Get the original tab textviews and remove them from the viewgroup.
TextView[] originalTextViews = new TextView[tabWidget.getTabCount()];
for (int index = 0; index < tabWidget.getTabCount(); index++) {
originalTextViews[index] = (TextView) tabWidget.getChildTabViewAt(index);
}
tabWidget.removeAllViews();
for (int index = 0; index < originalTextViews.length; index++) {
final TextView tabWidgetTextView = originalTextViews[index];
final View tabContentView = tabContent.getChildAt(index);
final TabHost.TabSpec tabSpec = tabHost.newTabSpec((String) tabWidgetTextView.getTag());
tabSpec.setContent(new TabHost.TabContentFactory() {
@Override
public View createTabContent(String tag) {
return tabContentView;
}
});
if (tabWidgetTextView.getBackground() == null) {
tabSpec.setIndicator(tabWidgetTextView.getText());
} else {
tabSpec.setIndicator(tabWidgetTextView.getText(), tabWidgetTextView.getBackground());
}
tabHost.addTab(tabSpec);
}
final TabWidget widget = tabHost.getTabWidget();
final int tabChildrenCount = widget.getChildCount();
LinearLayout.LayoutParams currentLayout;
for (int i = 0; i < tabChildrenCount; i++) {
currentLayout = (LinearLayout.LayoutParams) widget.getChildAt(i).getLayoutParams();
if (i == 0) {
currentLayout.setMargins(40, 0, 20, 0);
} else {
currentLayout.setMargins(20, 0, 40, 0);
}
}
widget.requestLayout();
originalTextViews = new TextView[tabWidget.getTabCount()];
for (int index = 0; index < tabWidget.getTabCount(); index++) {
originalTextViews[index] = (TextView) ((LinearLayout) tabWidget
.getChildTabViewAt(index)).getChildAt(1);
}
originalTextViews[0].setBackgroundResource(R.drawable.tableft);
originalTextViews[1].setBackgroundResource(R.drawable.tabright);
originalTextViews[0].setTextColor(Color.rgb(118, 119, 90));
originalTextViews[1].setTextColor(Color.rgb(227, 228, 206));
originalTextViews[0].setGravity(Gravity.CENTER);
originalTextViews[1].setGravity(Gravity.CENTER);
originalTextViews[0].setTypeface(null, Typeface.BOLD);
originalTextViews[1].setTypeface(null, Typeface.BOLD);
final LinearLayout tabFriends = (LinearLayout) findViewById(R.id.tabFriends);
// LinearLayout tabGroups = (LinearLayout)findViewById(R.id.tabGroups);
tabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener() {
@Override
public void onTabChanged(String tabId) {
if (tabId.compareTo("0") == 0) {
final ListView listView = getListView();
final MyAdapter adapter = new MyAdapter(FriendsAndGroups.this,
R.layout.friendsandgroupsrow, new String[] {
"singlesamplefortry"
});
listView.setAdapter(adapter);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
adapter.notifyDataSetChanged();
}
}
});
tabHost.setCurrentTab(1);
tabHost.setCurrentTab(0);
}
public class MyAdapter extends ArrayAdapter<String> {
public MyAdapter(Context context, int textViewResourceId, String[] objects) {
super(context, textViewResourceId, objects);
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
return getCustomView(position, convertView, parent);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
return getCustomView(position, convertView, parent);
}
public View getCustomView(int position, View convertView, ViewGroup parent) {
final LayoutInflater inflater = getLayoutInflater();
final View row = inflater.inflate(R.layout.friendsandgroupsrow, parent, false);
return row;
}
}
}
这是我的主要xml：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

，这是listview项目：

android:layout_height="50dp"
android:orientation="vertical"
android:paddingTop="5dp" >

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="4"
android:src="@drawable/profilepicturesmall" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:orientation="vertical" >
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:textColor="#76775a"
android:textStyle="bold" />
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:orientation="vertical" >
<TextView

</LinearLayout>
</LinearLayout>
</LinearLayout>
<LinearLayout

最后错误是：

答案 0 :(得分：0)
查看堆栈跟踪，看起来android在尝试加载位图时内存不足：

尝试制作"@drawable/profilepicturesmall"指向较小的图像。
