我有一个应该显示在某些图像上的特定位置的视图,我已经使用AbsoluteLayout做了,但我不想使用它,我试图用FrameLayout获得相同的结果.

但我不能让这个工作,这是我的两次尝试:

public void showVideo(RectF bounds) {
    FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) video.getLayoutParams();
    params.width = (int) bounds.width();
    params.height = (int) bounds.height();
    int x = (int) viewer.getPageXOffset();
    int y = (int) viewer.getPageYOffset();

    video.setPadding((int) (x + bounds.left), (int) (y + bounds.top), (int) (x + bounds.right),
            (int) (y + bounds.bottom));

    video.setLayoutParams(params);
    video.invalidate();

    video.setVisibility(View.VISIBLE);
    video.setFocusable(true);
    video.setFocusableInTouchMode(true);
    video.requestFocus();
}

和:

public void showVideo(RectF bounds, final String videoUrl) {
    FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) video.getLayoutParams();
    params.width = (int) bounds.width();
    params.height = (int) bounds.height();
    int x = (int) (viewer.getPageXOffset() …

如何在Android上打开PopupWindow并让所有其他组件都可以触摸而不会忽略PopupWindow？

这就是它的创建方式:

public class DynamicPopup {
    private final PopupWindow window;
    private final RectF rect;
    private final View parent;
    private final RichPageView view;

    public DynamicPopup(Context context, RichPage page, RectF rectF, View parent) {
        this.parent = parent;
        rect = rectF;

        window = new PopupWindow(context);

        window.setBackgroundDrawable(new BitmapDrawable());
        window.setWidth((int) rect.width());
        window.setHeight((int) rect.height());
        window.setTouchable(true);
        window.setFocusable(true);
        window.setOutsideTouchable(true);

        view = new RichPageView(context, page, false);
        window.setContentView(view);

        view.setOnCloseListener(new Listener(){
            @Override
            public void onAction() {
                window.dismiss();
            }
        });


    }

    public void show() {
        window.showAtLocation(parent, Gravity.NO_GRAVITY, (int) rect.left, (int) rect.top);
    } …

我正在创建一个可重复使用的加载屏幕以在活动之间使用,在LoadingActivity上我添加了一个半透明的背景资源,但是我无法看到旧的活动.

public class LoadingActivity extends Activity {
    public static int REQUEST_LOADING_SCREEN = 40;

    @Override
    protected void onCreate(Bundle savedInstance) {
        super.onCreate(savedInstance);

        FrameLayout mainLayout = new FrameLayout(this);

        mainLayout.setBackgroundResource(R.drawable.background_translucent);

        LinearLayout layout = new LinearLayout(this);
        layout.setGravity(Gravity.CENTER);

        LayoutParams params = LayoutParamsFactory.newMatchFrameLP();
        params.gravity = Gravity.CENTER;
        mainLayout.addView(layout, params);

        ProgressBar bar = new ProgressBar(this);
        bar.setIndeterminate(true);
        layout.addView(bar, LayoutParamsFactory.newWrapLinearLP());

        TextView text = new TextView(this);
        text.setText("Loading...");
        layout.addView(text, LayoutParamsFactory.newWrapLinearLP());

        setContentView(mainLayout);
    }

    public static void openFor(Activity activity) {
        Intent intent = new Intent(activity, LoadingActivity.class);
        activity.startActivityForResult(intent, REQUEST_LOADING_SCREEN);
    }

    public static void closeFrom(Activity activity) { …

我正在尝试为android编译本机程序.

但是当运行ndk-build命令时,我得到了以下结果.

/home/marcos/dev/workspace/rmsdk.native.wraper/jni/include-all/uft_alloc.h:26:21: error: stdexcept: No such file or directory
/home/marcos/dev/workspace/rmsdk.native.wraper/jni/include-all/uft_alloc.h:27:18: error: limits: No such file or directory

stdexcept和limits是std C++ lib的一部分.

这是我的Android.mk

LOCAL_PATH := $(call my-dir)
MY_PATH := $(LOCAL_PATH)
include $(call all-subdir-makefiles)
LOCAL_PATH := $(MY_PATH)
include $(CLEAR_VARS)

LOCAL_LDLIBS := -llog
LOCAL_MODULE    := rmsdk
LOCAL_SRC_FILES := curlnetprovider.cpp RMServices.cpp  
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include-all
LOCAL_STATIC_LIBRARIES := adept cryptopenssl curl dp expat fonts hobbes jpeg mschema png t3 xml zlib

include $(BUILD_SHARED_LIBRARY)

我应该明确告诉它它是一个C++源代码？

我已经知道如何在Android上将我的Activity作为全屏,现在我需要在此屏幕中绘制一个图像.

这是我的XML布局.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:id="@+id/image01" android:layout_width="fill_parent"
    android:layout_height="fill_parent" />
</LinearLayout>

此图像是动态生成的,并在ImageView中绘制.

这是我的活动代码.

public void onCreate(Bundle savedInstance) {
    super.onCreate(savedInstance);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.main);
}

但是在运行时,Activity是FullScreen,但ImageView在中心调整.

怎么了？

我添加了以下代码以查看组件尺寸.

    View view = getWindow().getDecorView();
    Log.i("RMSDK:J:IbaReader(decor)",
            "[w=" + view.getWidth() + ":h=" + view.getHeight() + "]");
    Log.i("RMSDK:J:IbaReader(img)",
            "[w=" + img.getWidth() + ":h=" + img.getHeight() + "]");

这导致两种情况下[w = 320:h = 480].

这是我的绘制方法.

private void draw() {
    byte[] image = services.getImageBuffer(600, 1024);
    Bitmap bmp = Bitmap.createBitmap(600, 1024, Bitmap.Config.RGB_565);
    int row = …

在为最新版本更新SDK和ADT之后,我尝试运行我的应用程序并且Eclipse记录以下错误:

我最近在用我的 Github 帐户登录的 gitlab 上创建了一个项目。

但是当使用 gitbash 克隆项目（将我当前的 ssh-key 添加到 gitlab 帐户）时，shell 会提示输入用户名/密码，从 github 输入我的用户名和密码会导致身份验证失败。（电子邮件/密码也失败）

我做错了什么？

我正在尝试将HTML5页面嵌入到我的应用程序中.

内容大于设备,所以我用它来缩放:

web.setInitialScale((int) (728 / 600 * 100)); //728 is the height of the page, 600 of the device

这样屏幕尺寸正确,但内容太小,我需要对其进行缩放控制.我尝试了WebView的supportZoom(true),缩放IN是正确的,但是当缩小时,这不会达到我的初始比例.

我最近重构了一个应用程序,并替换了一个FrameFayip,用于我在Fragments之间交换的FrameLayout.

每次用户请求其中一个视图:

    public void showLibraryOf(long publisherId) {
        library = new DownloadLibraryFragment(id, viewFactory());

        FragmentTransaction ft = getFragmentManager().beginTransaction();
        ft.replace(R.id.container, library);
        ft.commit();

        library.setAdapterObserver(this);
    }

    public void showMyLibraryOf(long publisherId) {
        myLibrary = new MyLibraryFragment(id, viewFactory());

        FragmentTransaction ft = getFragmentManager().beginTransaction();
        ft.replace(R.id.container, myLibrary);
        ft.commit();
    }

    public void showHelp() {
        FragmentTransaction ft = getFragmentManager().beginTransaction();
        ft.replace(R.id.container, new HelpFragment());
        ft.commit();
    }

我创建了一个新片段并替换旧片段.从屏幕上删除的那些被调用onDestroy,但是我在屏幕上加载的位图消耗的内存不会被删除,因此应用程序在片段之间进行一些交换后崩溃.

我还尝试删除onDestroy中的引用

@Override
public void onDestroyView() {
    destroy();
    super.onDestroyView();   
    adapter.clear();
    adapter.clearObservers();
    adapter.notifyDataSetChanged();

    view.setAdapter(new ArrayAdapter<Journal>(getActivity(), 0));

    adapter = null;
    view = null;
}

但记忆力不断增长.

谁知道任何解决方案？也许重用片段？有效地摧毁它？我在听.

我想知道哪些是Eclipse导航键盘快捷键.

我已经用过:

Ctrl+ Shift+ UP或DOWN导航槽方法

Ctrl+ ,或.在错误之间导航

Ctrl+ Page UP或DOWN在标签之间导航

UP或者DOWN在"Package Explorer"中导航项目结构并SPACE展开/折叠文件夹或打开文件

有了那些我几乎不使用鼠标,我想知道是否有一个快捷方式在日食内部窗口之间交换(到控制台底部,代码中间,任务权限,资源管理器左侧等)

谢谢
