android对话框活动位置

问题描述

我使用 android:theme="@android:style/Theme.Dialog" 创建了一个非最大化活动，使其看起来像一个对话框.我需要更改活动在屏幕上的位置，但我没有找到如何执行此操作...

I created an non-maximized activity using android:theme="@android:style/Theme.Dialog" to make it looks like a dialog. I need to change the position of the activity on screen but I didn't find how to do this...

推荐答案

要改变位置(主题设置为Theme.Dialog)，可以覆盖重力、大小和坐标活动装饰视图附加到窗口后的 LayoutParams.这是一个例子:

To change the position (with the theme set to Theme.Dialog), you can override the gravity, size and coordinates of the LayoutParams of your activity's decor view after it has been attached to the window. Here's an example:

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

    View view = getWindow().getDecorView();
    WindowManager.LayoutParams lp = (WindowManager.LayoutParams) view.getLayoutParams();
    lp.gravity = Gravity.LEFT | Gravity.TOP;
    lp.x = 10;
    lp.y = 10;
    lp.width = 300;
    lp.height = 300;
    getWindowManager().updateViewLayout(view, lp);
}
