如何通过单击按钮实现一些带有一些图像的小弹出窗口

当用户单击三个蓝点按钮时，我想要这样的弹出窗口。如何在android中实现这种类型的弹出视图。有图书馆可用吗？

您可以使用该库来实现您的目标

如果您要创建自定义类别，而不是使用以下类，则创建一个这样的自定义类别

public class TooltipWindow {

private static final int MSG_DISMISS_TOOLTIP = 100;
private Context ctx;
private PopupWindow tipWindow;
private View contentView;
private LayoutInflater inflater;

public TooltipWindow(Context ctx) {
    this.ctx = ctx;
    tipWindow = new PopupWindow(ctx);

    inflater = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    cOntentView= inflater.inflate(R.layout.tooltip_layout, null);
}

void showToolTip(View anchor) {

    tipWindow.setHeight(LayoutParams.WRAP_CONTENT);
    tipWindow.setWidth(LayoutParams.WRAP_CONTENT);

    tipWindow.setOutsideTouchable(true);
    tipWindow.setTouchable(true);
    tipWindow.setFocusable(true);
    tipWindow.setBackgroundDrawable(new BitmapDrawable());

    tipWindow.setContentView(contentView);

    int screen_pos[] = new int[2];
    // Get location of anchor view on screen
    anchor.getLocationOnScreen(screen_pos);

    // Get rect for anchor view
    Rect anchor_rect = new Rect(screen_pos[0], screen_pos[1], screen_pos[0]
            + anchor.getWidth(), screen_pos[1] + anchor.getHeight());

    // Call view measure to calculate how big your view should be.
    contentView.measure(LayoutParams.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT);

    int cOntentViewHeight= contentView.getMeasuredHeight();
    int cOntentViewWidth= contentView.getMeasuredWidth();
    // In this case , i dont need much calculation for x and y position of
    // tooltip
    // For cases if anchor is near screen border, you need to take care of
    // direction as well
    // to show left, right, above or below of anchor view
    int position_x = anchor_rect.centerX() - (contentViewWidth / 2);
    int position_y = anchor_rect.bottom - (anchor_rect.height() / 2);

    tipWindow.showAtLocation(anchor, Gravity.NO_GRAVITY, position_x, position_y);

    // send message to handler to dismiss tipWindow after X milliseconds
    handler.sendEmptyMessageDelayed(MSG_DISMISS_TOOLTIP, 4000);
}

boolean isTooltipShown() {
    if (tipWindow != null && tipWindow.isShowing())
        return true;
    return false;
}

void dismissTooltip() {
    if (tipWindow != null && tipWindow.isShowing())
        tipWindow.dismiss();
}

Handler handler = new Handler() {
    public void handleMessage(android.os.Message msg) {
        switch (msg.what) {
            case MSG_DISMISS_TOOLTIP:
                if (tipWindow != null && tipWindow.isShowing())
                    tipWindow.dismiss();
                break;
        }
    }

    ;
};

}

现在，为您的自定义布局（例如tooltip_layout）

像这样创建一个可绘制文件nav_up

现在像这样使用此工具提示

TooltipWindow tipWindow = new TooltipWindow(MainActivity.this);
 @Override
public void onClick(View v) {
    if (!tipWindow.isTooltipShown())
        tipWindow.showToolTip(v);
}
