我想表明我的android警报就像在桌面

我应该如何接近。

解决方案使它呈现这样

推荐答案

对话框不能没有一个活动被触发。

Dialogs cannot be triggered without an activity..

所以，你可以创建对话框主题的活动。

So ,you can create an activity with dialog theme.

    <activity android:theme="@android:style/Theme.Dialog" />

从服务..just称这种活动时，您的通知到达......它会弹出一个类似对话框现在...

Now from your service ..just call this activity when your notification arrives... And it will pop up like a dialog...

在呼唤你的活动：

   startActivity(intent);
   overridePendingTransition(R.anim.enter_anim, R.anim.right_exit_anim);

现在称为动画在资源DIR一个单独的文件夹中创建两个动画文件。

Now create the two anim files in a seperate folder called anim in the resource dir.

enter_anim：

enter_anim:

   <?xml version="1.0" encoding="utf-8"?>
   <set xmlns:android="http://schemas.android.com/apk/res/android"    
        android:interpolator="@android:anim/accelerate_decelerate_interpolator">
   <translate
    android:fromYDelta="20%p" //this takes val from 0(screenbottom) to 100(screentop).
    android:toYDelta="0%p"  //this takes val from 0(screenbottom) to 100(screentop).
    android:duration="700"   //transition timing
    />
   </set>

exit_anim：

exit_anim:

   <?xml version="1.0" encoding="utf-8"?>
   <set xmlns:android="http://schemas.android.com/apk/res/android"    
        android:interpolator="@android:anim/accelerate_decelerate_interpolator">
   <translate
    android:fromYDelta="0%p" //this takes val from 0(screenbottom) to 100(screentop).
    android:toYDelta="20%p"  //this takes val from 0(screenbottom) to 100(screentop).
    android:duration="700"   //transition timing
    />
   </set>

创建活动..设计it..then去你的清单文件。而你的活动标记下..添加：

Create an activity.. design it..then go to your manifest file.. And under your activity tag.. add:

    <activity android:theme="@android:style/Theme.Dialog" />

现在你的活动会看起来像一个对话框...

Now your activity will look like a dialog...

现在的onCreate（）后添加以下功能在您的活动（对话）

Now add the following function in your activity(dialog) after onCreate():

    @Override
public void onAttachedToWindow() {
    super.onAttachedToWindow();

    View view = getWindow().getDecorView();
    WindowManager.LayoutParams lp = (WindowManager.LayoutParams) view.getLayoutParams();
    lp.gravity = Gravity.RIGHT | Gravity.BOTTOM;//setting the gravity just like any view
    lp.x = 10;
    lp.y = 10;
    lp.width = 200;
    lp.height = 100;
    getWindowManager().updateViewLayout(view, lp);
}

我们正在覆盖附加窗口指定屏幕上的活动位置。

We are overriding the attach window to specify the activity location on the screen.

现在您的活动将被放置在屏幕的右侧底部。

Now your activity will be placed in the right side bottom of the screen.

现在给你指定的合作协调分的对话框中，使用lp.x和lp.y ...

Now to give your specified co ordinate points for the dialog, use the lp.x and lp.y...
