我想在MyPositionOverlay中绘制方法的位图扩展Overlay类但是我得到了这个错误:方法getResource()未定义类型MyPositionOverlay

哪里我错了？

这是代码表单绘制方法:

  Bitmap bmp = BitmapFactory.decodeResource(getResource(), R.drawable.icon); 
     canvas.drawBitmap(bmp, screenPts.x, screenPts.y-50, null);

谢谢

我的应用程序中有两个垂直TextView元素.TextViews之间有很多空间,pading和layoutMargin都是0

有没有办法减少这个空间？

            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:gravity="right"
            android:paddingRight="10dp"
            android:layout_weight="1">
                <TextView 
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"

                    android:text="Test1"/>
                <TextView 
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:textColor="@color/orange_text_color"
                    android:textSize="@dimen/text_size_large"
                    android:textStyle="bold"
                    android:text="Text2"/>

我想在popupwindow上设置左右边距.我尝试设置布局参数layout,然后设置保证金,但不起作用.

谁能给我代码在popupwindow上设置保证金

这是代码

LayoutInflater inflater = (LayoutInflater) QuestionsActiviy.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View layout = inflater.inflate(R.layout.popup, (ViewGroup) findViewById(R.id.popup_element));


        ratePw = new PopupWindow(layout);
        ratePw.setWidth(WindowManager.LayoutParams.FILL_PARENT);
        ratePw.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
        ratePw.setFocusable(true);

        ratePw.showAtLocation(layout, Gravity.CENTER, 0, 0);

谢谢.

我正在尝试将我现有的游戏(用libgdx编写)从Eclipse迁移到Android Studio.迁移我的桌面项目后正常工作,但我的Android项目有问题.在android我正在使用Admob广告.

我收到以下错误消息:

如您所见,Android Support Repository已安装

我的项目结构:

在Project Gradle文件中,我有这个:

我是Unity新手。

有人可以告诉我这个错误是什么意思

粒子系统需要在开始时播放，但有时不需要工作（播放效果）。谢谢

我将这个选择器代码用于我的自定义按钮(simple.xml)

  <?xml version="1.0" encoding="utf-8"?>

  <selector xmlns:android="http://schemas.android.com/apk/res/android">
      <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/focused" />
      <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/focusedpressed" />
      <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/pressed" />
      <item android:drawable="@drawable/defaultbutton" />
  </selector>

但在我的ImageButton上,我不知道如何删除边框.我想只显示我的图像,不显示按钮周围的边框.

谢谢

如何将ImageButton置于此LinearLayout中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/main"
>

的ImageButton

              <ImageButton android:id="@+id/btnBut"
                      android:background="@drawable/button"
                      android:layout_width="wrap_content"
                      android:layout_height="wrap_content" />

我不想使用固定尺寸.

谢谢

今天我已将Android Studio更新为v1.5.我有libgdx项目,在此更新之前运行良好.现在我收到此错误消息.

我使用PopupWindow类创建自定义弹出窗口.

但是当我在main上添加layout_margin(在我的示例中为15dp)时,会有透明的灰色背景.

如何删除透明背景？

请看图片

编辑这里是我的代码

    window = new PopupWindow(customTool.getContext());
    window.setWidth(WindowManager.LayoutParams.FILL_PARENT);
    window.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
    window.setTouchable(true);
    window.setFocusable(true);
    window.setOutsideTouchable(true);
    window.setAnimationStyle(R.style.Animations_PopDownMenu_Left);
window.setContentView(customTool);
    window.showAtLocation(customTool, Gravity.NO_GRAVITY, 0, 100);

我正在用libGDX制作游戏.

我想实现游戏控制,但我的touchDown方法有问题.touchDown方法只运行一次.我想在touchDown中循环,直到调用touchUp.有人能帮我吗 ？

class  onPlayerGoLeftListener extends InputListener {

    public boolean touchDown (InputEvent event, float x, float y, int pointer, int button) {
        //start runnable   (move player)     

        return true;
    }

    public void touchUp (InputEvent event, float x, float y, int pointer, int button) {
        //stop runnable
    }

}

谢谢

ps我不喜欢使用主更新方法来做到这一点
