Question

我必须实现一个看起来像这样的自定义对话框，并且应该有一个特殊的位置，比如我需要将它附加到某个组件。

你能不能给我一些实施想法？

我正在考虑覆盖现有的Android Dialog组件，但我不确定我是否可以像这样实现此功能。

非常感谢任何链接参考或想法。 enter image description here

Answer 1

您需要做的就是创建一个与任何其他布局完全相同的XML并对其进行充气。

final Dialog dialog = new Dialog(this);

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
//here is where you inflate your XML for the dialog
dialog.setContentView(R.layout.your_dialog_xml);

//now you can grab a reference to any component in your given xml like this
Button exampleButton = (Button) dialog.findViewById(R.id.my_xml_button);

//add any listeners etc.

//display your dialog
dialog.show();

Answer 2

创建一个类Dialog类的子类，并在其中设置setContentView的自定义视图，这将使您的代码更清晰。看到这里的样本

我有一个相同的要求，希望这会有所帮助。 ::

CUSTOM DIALOG CLASS

public class CustomDialogShape extends View {

public int startPointY,startPointX;
public int windowWidth; 
public int dialogWidth, dialogHeight;
public int leftTop, rightTop;
public CustomDialogShape(Context context) {
    super(context);
}

/**
 * 
 * @param XPos
 * @param YPos
 * @param windowWidth
 * @param dialogHeight
 * @param dialogWidth
 * Get the Click position, dialog dimension and window width from the parent window
 * calculate the co-ordinates to draw the custom dialog shape
 */
public void setDimension(int XPos, int YPos, int windowWidth, int dialogHeight, int dialogWidth) {
    this.startPointY = YPos;
    this.startPointX = XPos;
    this.windowWidth = windowWidth;
    this.dialogHeight = dialogHeight;
    this.dialogWidth = dialogWidth;

    if(startPointX <= (windowWidth/2)) {
        //Start Position is on the left half of the Screen
        if(startPointX < (dialogWidth/2)) {
            //Start position is on the leftmost end.
            leftTop = 10;
            rightTop = leftTop + dialogWidth;
        } else {
            leftTop = startPointX - (dialogWidth/2);
            rightTop = leftTop + dialogWidth;
        }
    } else {
        int rightSideRemaining = windowWidth - startPointX;
        if(rightSideRemaining < (dialogWidth/2)) {
            //Start position is on the leftmost end.
            rightTop = windowWidth - 10;
            leftTop = rightTop - dialogWidth;
        } else {
            rightTop = startPointX + (dialogWidth/2);
            leftTop = rightTop - dialogWidth;
        }
    }


}

public CustomDialogShape(Context context, AttributeSet at) {
    super(context, at);
}


/**
 * Fill and Stroke Color
 */
@Override 
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);

    // custom drawing code here
    // remember: y increases from top to bottom
    // x increases from left to right
    Paint paint = new Paint();
    paint.setColor(Color.BLACK);
    canvas.drawPath(drawCustomShape(startPointX, startPointY, leftTop, rightTop), paint);
    paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeWidth(3);
    paint.setColor(Color.GRAY);
    canvas.drawPath(drawCustomShape(startPointX, startPointY, leftTop, rightTop), paint);
}


private Path drawCustomShape(int startPointX, int startPointY, int leftTop, int rightTop) {
    Path pathFill = new Path();
    pathFill.moveTo(startPointX, startPointY);
    pathFill.lineTo(startPointX - 10, startPointY + 10);
    pathFill.lineTo(leftTop, startPointY + 10);
    pathFill.lineTo(leftTop, startPointY + 10 + dialogHeight);
    pathFill.lineTo(rightTop, startPointY + 10 + dialogHeight);
    pathFill.lineTo(rightTop, startPointY + 10);
    pathFill.lineTo(startPointX + 10, startPointY + 10);
    pathFill.lineTo(startPointX, startPointY);
    pathFill.close();
    return pathFill;
}

<强> MyLAYOUT.XML

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

<com.cablevision.optimum2.widget.CustomDialogShape

在我的代码中

                 Rect r = locateView(activity.findViewById(View_where_you_touch));


    float touchX= //get the touchx position by calculating through r.leftand r.right);              
            float touchY=r.bottom;
 final Dialog dialog = new Dialog(Ctxt,
                    android.R.style.Theme_Translucent_NoTitleBar);                                  

        dialog.getWindow().
setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);    
            dialog.setContentView(R.layout.MyLAYOUT);
            CustomDialogShape custom = (CustomDialogShape) chnSTBDialog
                    .findViewById(R.id.custom_shape);
                            custom.setDimension( touchX,  touchY, custom_shape_width,
                    custom_shape_height , totalwindowWidth));                

public static Rect locateView(View view) {
    Rect loc = new Rect();
    int[] location = new int[2];
    if (view == null) {
        Logging.e(TAG, "locateView", "View not found");
}

在myLAYOUT XML中我有自己的列表，您可以根据需要更改内容，就像它可以是线性布局一样。希望这有帮助

Answer 4

您可以构建如下自定义对话框：

Dialog mDialog; 

mDialog = new Dialog(YourActivityName.this);
            mDialog.setContentView(R.layout.checklist_navigatepop);//XML layout file
            mDialog.setTitle("Navigation alert");
            mDialog.setCancelable(true);
            mDialog.show();

            Button bt = (Button) mDialog.findViewById(R.id.button3);
            Button bt1 = (Button) mDialog.findViewById(R.id.button2);

            bt.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    onBackPressed();

                    mDialog.dismiss();
                }
            });

Answer 5

您不需要扩展Dialog类。

你需要这样的东西。

public Dialog buildDialog() {

Dialog messageDialog = new Dialog(context, android.R.style.Theme_Translucent);

messageDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

// Set your custom layout here.
messageDialog.setContentView(R.layout.dialog_wifi_disabled);

// Don't let the user cancel the dialog.
messageDialog.setCancelable(false);
messageDialog.setCanceledOnTouchOutside(false);

// You can get the views, like this.
TextView textView = (TextView) messageDialog.findViewById(R.id.your_view);

}
