设置视图的绝对位置。

时间:2021-08-21 08:37:04

Is it possible to set the absolute position of a view in Android? (I know that there is an AbsoluteLayout, but it's deprecated...)

是否可以在Android中设置视图的绝对位置?(我知道有一个绝对的尝试,但它是不赞成的…)

For example, if I have a 240x320px screen, how could I add an ImageView which is 20x20px such that its center is at the position (100,100)?

例如,如果我有一个240x320px的屏幕,我怎么能添加一个20x20px的ImageView,它的中心在这个位置(100,100)?

You can use RelativeLayout. Let's say you wanted a 30x40 ImageView at position (50,60) inside your layout. Somewhere in your activity:

您可以使用使用。假设你想在布局中放置一个30x40的ImageView(50,60)。在你的活动:

// Some existing RelativeLayout from your layout xml
RelativeLayout rl = (RelativeLayout) findViewById(R.id.my_relative_layout);

ImageView iv = new ImageView(this);

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);

More examples:

更多的例子:

Places two 30x40 ImageViews (one yellow, one red) at (50,60) and (80,90), respectively:

在(50,60)和(80,90)分别放置两个30x40图像视图(一个黄色,一个红色)和(80,90):

RelativeLayout rl = (RelativeLayout) findViewById(R.id.my_relative_layout);
ImageView iv;
RelativeLayout.LayoutParams params;

iv = new ImageView(this);
iv.setBackgroundColor(Color.YELLOW);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);

iv = new ImageView(this);
iv.setBackgroundColor(Color.RED);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 80;
params.topMargin = 90;
rl.addView(iv, params);

Places one 30x40 yellow ImageView at (50,60) and another 30x40 red ImageView <80,90> relative to the yellow ImageView:

在(50,60)处放置一个30x40黄色的ImageView,以及另一个30x40的红色ImageView <80,90>相对于黄色的ImageView:

RelativeLayout rl = (RelativeLayout) findViewById(R.id.my_relative_layout);
ImageView iv;
RelativeLayout.LayoutParams params;

int yellow_iv_id = 123; // Some arbitrary ID value.

iv = new ImageView(this);
iv.setId(yellow_iv_id);
iv.setBackgroundColor(Color.YELLOW);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);

iv = new ImageView(this);
iv.setBackgroundColor(Color.RED);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 80;
params.topMargin = 90;

// This line defines how params.leftMargin and params.topMargin are interpreted.
// In this case, "<80,90>" means <80,90> to the right of the yellow ImageView.
params.addRule(RelativeLayout.RIGHT_OF, yellow_iv_id);

rl.addView(iv, params);

In general, you can add a View in a specific position using a FrameLayout as container by specifying the leftMargin and topMargin attributes.

通常,您可以通过指定leftMargin和topMargin属性,在特定的位置添加视图,使用FrameLayout作为容器。

The following example will place a 20x20px ImageView at position (100,200) using a FrameLayout as fullscreen container:

下面的示例将使用FrameLayout作为fullscreen容器在position(100,200)处放置一个20x20px的ImageView (100,200):

XML

XML

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/root"
    android:background="#33AAFF"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
</FrameLayout>

Activity / Fragment / Custom view

活动/片段/自定义视图。

//...
FrameLayout root = (FrameLayout)findViewById(R.id.root);
ImageView img = new ImageView(this);
img.setBackgroundColor(Color.RED);
//..load something inside the ImageView, we just set the background color

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(20, 20);
params.leftMargin = 100;
params.topMargin  = 200;
root.addView(img, params);
//...

This will do the trick because margins can be used as absolute (X,Y) coordinates without a RelativeLayout:

这将会起作用,因为边距可以被用作绝对(X,Y)坐标,而不需要相对的:

设置视图的绝对位置。

Just to add to Andy Zhang's answer above, if you want to, you can give param to rl.addView, then make changes to it later, so:

如果你愿意的话,我想补充一下安迪·张的答案,你可以把param给rl。addView,然后对它进行修改,所以:

params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);

Could equally well be written as:

同样可以写成:

params = new RelativeLayout.LayoutParams(30, 40);
rl.addView(iv, params);
params.leftMargin = 50;
params.topMargin = 60;

So if you retain the params variable, you can change the layout of iv at any time after adding it to rl.

因此,如果您保留了params变量,您可以在添加到rl之后随时更改iv的布局。

A more cleaner and dynamic way without hardcoding any pixel values in the code.

一种更简洁、更动态的方法,无需在代码中硬编码任何像素值。

I wanted to position a dialog (which I inflate on the fly) exactly below a clicked button.

我想要定位一个对话框(我在飞行中充气)正好在一个点击按钮下面。

and solved it this way :

这样解决了:

    // get the yoffset of the position where your View has to be placed 
    final int yoffset = < calculate the position of the view >

    // position using top margin
    if(myView.getLayoutParams() instanceof MarginLayoutParams) {
        ((MarginLayoutParams) myView.getLayoutParams()).topMargin = yOffset;
    }

However you have to make sure the parent layout of myView is an instance of RelativeLayout.

但是,您必须确保myView的父布局是相对布局的实例。

more complete code :

更完整的代码:

    // identify the button
    final Button clickedButton = <... code to find the button here ...>

    // inflate the dialog - the following style preserves xml layout params
    final View floatingDialog = 
        this.getLayoutInflater().inflate(R.layout.floating_dialog,
            this.floatingDialogContainer, false);

    this.floatingDialogContainer.addView(floatingDialog);

    // get the buttons position
    final int[] buttonPos = new int[2];
    clickedButton.getLocationOnScreen(buttonPos);        
    final int yOffset =  buttonPos[1] + clickedButton.getHeight();

    // position using top margin
    if(floatingDialog.getLayoutParams() instanceof MarginLayoutParams) {
        ((MarginLayoutParams) floatingDialog.getLayoutParams()).topMargin = yOffset;
    }

This way you can still expect the target view to adjust to any layout parameters set using layout XML files, instead of hardcoding those pixels/dps in your Java code.

这样,您仍然可以期望目标视图根据布局XML文件对任何布局参数进行调整,而不是在Java代码中硬编码那些像素/dps。

My code for Xamarin, I am using FrameLayout for this purpose and following is my code:

我的Xamarin代码,我正在使用FrameLayout,下面是我的代码:

               List<object> content = new List<object>();

        object aWebView = new {ContentType="web",Width="300", Height = "300",X="10",Y="30",ContentUrl="http://www.google.com" };
        content.Add(aWebView);
        object aWebView2 = new { ContentType = "image", Width = "300", Height = "300", X = "20", Y = "40", ContentUrl = "https://www.nasa.gov/sites/default/files/styles/image_card_4x3_ratio/public/thumbnails/image/leisa_christmas_false_color.png?itok=Jxf0IlS4" };
        content.Add(aWebView2);
        FrameLayout myLayout = (FrameLayout)FindViewById(Resource.Id.frameLayout1);
        foreach (object item in content)
        {

            string contentType = item.GetType().GetProperty("ContentType").GetValue(item, null).ToString();
            FrameLayout.LayoutParams param = new FrameLayout.LayoutParams(Convert.ToInt32(item.GetType().GetProperty("Width").GetValue(item, null).ToString()), Convert.ToInt32(item.GetType().GetProperty("Height").GetValue(item, null).ToString()));
            param.LeftMargin = Convert.ToInt32(item.GetType().GetProperty("X").GetValue(item, null).ToString());
            param.TopMargin = Convert.ToInt32(item.GetType().GetProperty("Y").GetValue(item, null).ToString());

            switch (contentType) {
                case "web":{
                        WebView webview = new WebView(this);

                        //webview.hei;
                        myLayout.AddView(webview, param);
                        webview.SetWebViewClient(new WebViewClient());
                        webview.LoadUrl(item.GetType().GetProperty("ContentUrl").GetValue(item, null).ToString());

                        break;
                    }
                case "image":
                    {
                        ImageView imageview = new ImageView(this);

                        //webview.hei;
                        myLayout.AddView(imageview, param);
                        var imageBitmap =  GetImageBitmapFromUrl("https://www.nasa.gov/sites/default/files/styles/image_card_4x3_ratio/public/thumbnails/image/leisa_christmas_false_color.png?itok=Jxf0IlS4");
                        imageview.SetImageBitmap(imageBitmap);


                        break;
                    }

            }

        }

It was useful for me because I needed the property of view to overlap each other on basis of their appearance, e.g the views get stacked one above other.

这对我很有用,因为我需要视图的属性在它们的外观的基础上相互重叠。这些视图叠加在一起。

Just in case it may help somebody, you may also try this animator ViewPropertyAnimator as below

如果它可以帮助某些人,您也可以尝试下面的animator ViewPropertyAnimator。

myView.animate().x(50f).y(100f);

myView.animate().translateX(pixelInScreen) 

Note: This pixel is not relative to the view. This pixel is the pixel position in the screen.

注意:这个像素与视图无关。这个像素就是屏幕上的像素位置。

Try below code to set view on specific location :-

尝试下面的代码来设置特定位置的视图:-。

            TextView textView = new TextView(getActivity());
            textView.setId(R.id.overflowCount);
            textView.setText(count + "");
            textView.setGravity(Gravity.CENTER);
            textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 12);
            textView.setTextColor(getActivity().getResources().getColor(R.color.white));
            textView.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    // to handle click 
                }
            });
            // set background 
            textView.setBackgroundResource(R.drawable.overflow_menu_badge_bg);

            // set apear

            textView.animate()
                    .scaleXBy(.15f)
                    .scaleYBy(.15f)
                    .setDuration(700)
                    .alpha(1)
                    .setInterpolator(new BounceInterpolator()).start();
            FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(
                    FrameLayout.LayoutParams.WRAP_CONTENT,
                    FrameLayout.LayoutParams.WRAP_CONTENT);
            layoutParams.topMargin = 100; // margin in pixels, not dps
            layoutParams.leftMargin = 100; // margin in pixels, not dps
            textView.setLayoutParams(layoutParams);

            // add into my parent view
            mainFrameLaout.addView(textView);

                        //webview.hei;
                        myLayout.AddView(webview, param);
                        webview.SetWebViewClient(new WebViewClient());
                        webview.LoadUrl(item.GetType().GetProperty("ContentUrl").GetValue(item, null).ToString());

                        break;
                    }
                case "image":
                    {
                        ImageView imageview = new ImageView(this);

                        //webview.hei;
                        myLayout.AddView(imageview, param);
                        var imageBitmap =  GetImageBitmapFromUrl("https://www.nasa.gov/sites/default/files/styles/image_card_4x3_ratio/public/thumbnails/image/leisa_christmas_false_color.png?itok=Jxf0IlS4");
                        imageview.SetImageBitmap(imageBitmap);


                        break;
                    }

            }

        }

It was useful for me because I needed the property of view to overlap each other on basis of their appearance, e.g the views get stacked one above other.

这对我很有用,因为我需要视图的属性在它们的外观的基础上相互重叠。这些视图叠加在一起。

Just in case it may help somebody, you may also try this animator ViewPropertyAnimator as below

如果它可以帮助某些人,您也可以尝试下面的animator ViewPropertyAnimator。

myView.animate().x(50f).y(100f);

myView.animate().translateX(pixelInScreen) 

Note: This pixel is not relative to the view. This pixel is the pixel position in the screen.

注意:这个像素与视图无关。这个像素就是屏幕上的像素位置。

Try below code to set view on specific location :-

尝试下面的代码来设置特定位置的视图:-。

            TextView textView = new TextView(getActivity());
            textView.setId(R.id.overflowCount);
            textView.setText(count + "");
            textView.setGravity(Gravity.CENTER);
            textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 12);
            textView.setTextColor(getActivity().getResources().getColor(R.color.white));
            textView.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    // to handle click 
                }
            });
            // set background 
            textView.setBackgroundResource(R.drawable.overflow_menu_badge_bg);

            // set apear

            textView.animate()
                    .scaleXBy(.15f)
                    .scaleYBy(.15f)
                    .setDuration(700)
                    .alpha(1)
                    .setInterpolator(new BounceInterpolator()).start();
            FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(
                    FrameLayout.LayoutParams.WRAP_CONTENT,
                    FrameLayout.LayoutParams.WRAP_CONTENT);
            layoutParams.topMargin = 100; // margin in pixels, not dps
            layoutParams.leftMargin = 100; // margin in pixels, not dps
            textView.setLayoutParams(layoutParams);

            // add into my parent view
            mainFrameLaout.addView(textView);
