这是我的XML 2 LinearLayouts.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent">
    <LinearLayout
            android:id="@+id/ll_one"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            />
    <LinearLayout
            android:id="@+id/ll_two"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            />
</LinearLayout>

我从http://android.arnodenhond.com/components/graphview下载了GraphView .这个类扩展了View.我基本上想要初始化2个图表

String[] verlabels = new String[]{"aim", "25%", "50%", "75%", "start"};
String[] horlabels = new String[]{"this", "max"};

float[] values = new float[]{2.0f, 6.0f};
aaaGraphView graphView = new aaaGraphView(this, values, "Graph One",
        horlabels, verlabels, aaaGraphView.BAR);

float[] values2 = new float[]{1.0f, 12.0f};
aaaGraphView graphView2 = new aaaGraphView(this, values2, "Graph Two",
        horlabels, verlabels, aaaGraphView.BAR);

然后膨胀graphView到ll_one,graphView2 …

我似乎不明白是否可以将一项活动(包括)扩展到另一项活动中.我知道我可以膨胀布局xml,这可行,但我想知道我是否可以膨胀一项活动.例如,我有一个扩展Activity的类A和一个扩展ListActivity的另一个类B. 我可以在A级,我的B级包括和使用吗？这是我试过的:

A类:

LayoutInflater inflater = (LayoutInflater) MyActivity.this
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    // inflate list
    BActivity list = new BActivity();

B级:

public class BActivity extends ListActivity {
  public void onCreate(Bundle bundle) {
    super.onCreate(bundle);

    List<Model> models= new ArrayList<Model>();
    models.add(new Model("John"));
    models.add(new Model("Cage"));

    setListAdapter(new MyAdapter(this, models));
    ListView list = getListView();
  }
}

并在xml(类A xml)中:(我希望在哪里看到列表)

 <view class="com.test.BActivity"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >  </view>

所有这些都会引发错误:

膨胀类BActivity时出错

活动在清单中声明.

你知道我做错了什么吗？这不是扩充另一项活动的正确方法吗？我使用的是Android 2.2 api 8.谢谢你的时间.

我已经在Android(树视图)中以编程方式构建了一个布局,现在我想在构建视图中添加一个topbar(topbar.xml).

所以我需要的不是:

setContentView(scroll)

就像是:

inflateInMyViewCalledScroll(topbar.xml)
setContentView(scroll)

谢谢你的建议

我有两个Buttons主要布局.如果Button单击添加,则必须EditText动态添加(使用Inflater).这部分正在运作.如果Button单击" 删除" ,则必须先删除那些EditText带有最后一个的内容.但我不知道如何删除视图.

add.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            view = layoutInflater.inflate(R.layout.add_edit, null);
            ll.addView(view);
        }
    });
    remove.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            ll.removeViewAt(0);
        }
    });

我正在尝试创建一个自定义视图 - 手指画,我遇到此错误的麻烦,我不知道如何解决它.谁能告诉我有什么问题？

请帮帮我,这是我最近两天打砖墙,无法弄明白.

我有一个简单的PreferenceFragment,并希望从一个Activity中膨胀它.

这是res/xml/preferences.xml:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
    android:key="preferences">
<PreferenceCategory
        android:title="@string/notification_basic"
        android:key="notification">
    <CheckBoxPreference

    </CheckBoxPreference>
    <CheckBoxPreference
            android:key="enable"
            android:summary="@string/enable_instant_notification"
            android:title="@string/notify_me_instantly"
            android:dependency="enable_notification"
            android:defaultValue="false">

</PreferenceCategory>
<PreferenceCategory

            android:entries="@array/locations"
            android:entryValues="@array/locations_values"
            android:defaultValue="@array/empty_array"
            android:dependency="enable_notification"
            />
</PreferenceCategory>
<PreferenceCategory
        android:title="@string/sign_up_notify_me_type_section"
        android:key="types">

            android:dependency="enable_notification"
            />
</PreferenceCategory>
<PreferenceCategory
        android:title="@string/sign_up_notify_me_who_section"
        android:key="units">
    <MultiSelectListPreference
            android:dialogTitle="@string/sign_up_notify_me_who_title"
            android:key="units"

            android:title="@string/sign_up_notify_me_who_title"
            android:entries="@array/units"

            android:defaultValue="@array/empty_array"
            android:dependency="enable_notification"
            />
    </PreferenceCategory>
</PreferenceScreen>

活动:

public class HomeActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState); …

好吧'我有一个RelativeLayout

    <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="wrap_content"
    android:clickable="true"
    android:background="@drawable/my_shape_normal"
    android:onClick="startTestTillError">

my_shape_normal定义为

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
    android:startColor="#FFFFFF00"
    android:endColor="#80FFFFFF"
    android:angle="120"/>
<padding android:left="7dp"
    android:top="7dp"
    android:right="7dp"
    android:bottom="7dp" />
<corners android:radius="8dp" />
</shape>

在加载时会引发异常:在RelativeLayout行的android.view.InflateException.如果我删除"android:background",一切都很完美.my_shape_normal出了什么问题？

我正在尝试使用动作模式获取上下文菜单,我可以通过长按它来选择ListView中的项目.我根据此引用创建了一个MultiChoiceListener,并创建了一个ItemLongClickListener,它将一个项设置为已选中,这是操作模式根据此引用工作所需的.

我的问题是,即使项目长时间点击动画正在播放,ActionMenu也不会膨胀.

ListView代码:

final ListView listView = (ListView) findViewById(android.R.id.list);
        listView.setAdapter(adapter);
        listView.setLongClickable(true);
        listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
        listView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long id) {

            Cursor cursor = db.getSubject(id);
            String subject = null;
            try {
                subject = cursor.getString(cursor.getColumnIndex("subject"));
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            Intent intent = new Intent(Main.this, Marks.class);
            intent.putExtra("selected", subject);
            startActivity(intent);
            }
        });
        listView.setOnItemLongClickListener(new OnItemLongClickListener() {

            @Override
            public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                    int arg2, long …

我正在调用setLayoutData()许多地方的函数,我想在每次调用时清除视图.现在发生了什么布局得到追加.但是我不想追加我们如何清除视图.请帮助我这是我的功能

void setLayoutData() {
        resultTrips = (LinearLayout) findViewById(R.id.trip_list);
        LinearLayout.LayoutParams mainTripDetailsLayout = new LinearLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        LayoutInflater inflater = (LayoutInflater) getBaseContext()
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        for (int i = 0;i<4;i++) {
            final LinearLayout tripdetailsdata = (LinearLayout) inflater
                    .inflate(R.layout.mytripinner, null);
            tripdetailsdata.setId(i);
            resultTrips.addView(tripdetailsdata);
            i++;
        }
        TextView dummy = new TextView(this);
        dummy.setLayoutParams(mainTripDetailsLayout);
        resultTrips.addView(dummy);
    }

首先,请任何人可以告诉我是否可以在没有XML的情况下充气视图？

描述是这样的:
我通过编码动态生成了一个视图层次结构

Relative layout contain 4 Linear layouts
-1st Linear Layout contain Image View
-2nd Linear Layout contain surface view
-3rd Linear Layout contain Button
-4th Linear Layout contain Text Box

并且生成所有视图/视图层次结构没有问题(我通过调试和检查子视图进行测试)

但是我无法将其设置为setContent()
因为我没有XML而且不允许使用XML(不是确定为什么),即我无法访问R.Layout.所以我不能使用inflater.Inflate(R.Layout ...)

当我将主要相对布局设置为内容时,我收到以下错误

12-16 11:32:03.653: E/AndroidRuntime(22564): java.lang.RuntimeException: Unable to start activity ComponentInfo{my.package.class}: android.content.res.Resources$NotFoundException: Resource ID #0x1d97b

任何人都有任何想法？
